INTRODUCTION

Tills article presents a model of three development stages that shows how industrial te4,hnology develops over time and how the characteristics of international transfer of technology, the pro0uction process structure, and local~ ;irms' inr:ovation strategic:; evolve in response to the changing competitive

env~ronntent in an industrializing coutry, Korea. Fechnological change is known to have bc,'n a major determinant of nationai~ deve|opment. In industri,:lized economies, many studies ~,ve shown that more than 50 percept of lorg ~etm economic grewth ~,tems from technological changes which improve productivity or lead to new pr,,-cacts, processes or industries [7]. Fo; this reason, the question otter~ raised is how can science and technology, which appear to be the key to development ir~ the

more advanced countries, be effectively used tor economic and socl.al development in the less developec regions of the world. Previous studies have :3ugh+ to answer many important questions related to

science and technology and their role in the development of less developed countries. These studies ma3 be roughly classified into two categories. Studies

in the first categot3' are on science and technology and their role in the development of LDCs. They are mainly concerned with the development and role

of the local scientific community, the role of education, and effects of science and technology policy on industrial development. Moravcsik [17] lists al- mosl 500 publications on v:,rious aspects of tllis issue. Studies in the second

category are concerned with the ir:ternational trartsfe, of technology to LDCs; that is, the rove of multination, al firms in technology tran ,~, the problems associ,)t~d with importation and at, aptation of foreign te.':hnology, and the role of lo,,:al R&D institutions. Steele [24] lists over 200 studies in this ar,~a.

This study is a dis:,nct departure from the previous studi~, in that it ,everses

the approach, looking at the level of firms to identify the pa.~,ml of when ar,~ why local !:'irms acquire ~breign technologies, how they assimilate ant! improve importec technology to strengthen their competitiveness in a changing environment, and wheh government programs and other external factors affect the pro,ces.~, of technological change in firms. This approach is useful and important, ~incz government uses a variety of programs within tile general frameworI~ c7 their industrial policies in ,order to i"quence the process of ted~,nologic~l cha1~ge at the firm level. Similarly, I: oth m~ldnatic, nal comp,.

.hies that supply forei~l technologies and local R&D institutions d- ch help

local firms import, adapt and improv such technologies also interact prima- ally at the level of fi~m~.

This a~ ~ic]e first presents an three-stage raodel of whea and hew local firr s in a LDC import and implement, assimilate, and improve foreign '.echnologies in response to the ch~,uging competitive environment. This mc)del is ba~ed on the primary data collected from 31 consume: and industrial electronic products manufacturel:s and the secondary data on the electronics i~.dustry in Korea. The applicability ~" the model o other industri,~ ~ sectors in Korea and other countries is then discussed. Finzlb, the article o,fers a set of propositions that can be ~esearched in future ir . :her industries in other developing countries.

Korea is one of the mos" rapidly indt,strializing countrL's in the world. Its GDP increased at the annual rat ~ of over 10% between 1965 and 1975, one of the highest growth rates. Its manufacturing secte; has grown during the same period with the annual rate of 22.4%, noticeably faster than the economic growth in general I26].

The electronics industry in Korea in which this study w,,s undertaken is the fastest growing industry in Korea. Since I966, the industry produc,ion volume has grown more than 50% every ye~Lr. Ey'ports have increased more than

100 times flom 1966 to 1975 and the number of firms has increased frvm 70 to 457 duri:ag the same period. Of these 457, 102 firms produced the end products in ~975 [6]. The 31 firms were ~;elected from these 102 firms on the basis of 'chunk' sampling techniques so as lo have representative ~amplings on

an a .~riori I:asls through multi-stages (see [14] for the sampling techniq~ae). Fir~v~ covered in this study produce TV sets, radio, stereo sets. tape recor-

eact product production in the electronic~ industry in 1975.

~qTAGES OF DEVELOPMENF OF INDUSTRIAL TECHNOLOGY: A MOi~EL

This study does not include wh ~lly-owned foreign subsidiaries, zts they, parti- cularly off-shore assem ~ ly q~,..,, behave differently from national and joint- venture firms.*

in recent decades :Icveloping countries have employed various efforts at industrialization. The N:~,S's ad l,,.c panel of the Board on Science and Techno- logy describes tb. ~ general pattern of development for these countries in the fifllowing terms:

Tl~e principal industriaPzation strategy of most LDCs during the early postwar years is ~aid ~,.', have been import substitution; domestic production, under the shelter of a high tariff wall and ustally under monopoly conditions, cf goods that w ~.re formerly imported. By the end .ff the lC~60s, export promotion as a strategy for development had become a full partner of, if not a replacement for, import substitution. This change increased I_DC interest in strengthening the technological capabilities of local enterprise - exporters must sell a: competitive prices. A basic reason for fostering indigenous RD&E is to. combine engineering skills, which are becoming more plentiful in the LDCs, with first hand knowledge ,~f local productive capabilities and social customs and both local and foreign product requirements [19].

Like many other developin:g countries. Korea has e~:lployed this pattern of industrialization [25]. "i'he electronics industry was initially established in response to a market opport~Jnity created and protecte t by a government im-

Manufacturing subsidiaries of foreign corporations have a high dependence on their parent companies for prodact design and production tec!miques. For example, off- shore assembly soosidiaries perform no more than asse~nbly operation of foreign components and parts for reexport purpos,~. In this cas,, ~. products and theft components and proOuction processes are developed by parent companies. Even foreign subsidiaries that manufactt~re products for local markets perform no more than adaptive engineering of product design and prodvction techniques developed b., p~rent companies to local conditions as viewed ne'~essary by the latter. In contrast, local firms evolve in their technological capabilities from implementation, to assi- maation, and to improvement of foreign teclmologies [ 1, 2, 10].

port sub.stitution policy. In most cases, product design and production tech. nologies had to be importec!t from overseas. Production at this stage was mere- ly an assembly operation ,~f foreign components and parts, and the firm's

technological concern was essentially for the implementation of a production operation. There were few indigenous efforts to undertake technological change in products and processes due to the lack of both technological capability and market incentive..; to bring about ci~ange. As product design and production techniques transferred from overseas were successfully implemented at several firms, technical knowhow was quickly diffused within the country, resulting in an increased number of firms com- peting in the same marke~:. AccumaLated exnerience in product design and production provided a basis for limi~r:ed indigel:ous efforts for the assimilation of foreign technologies. Finally, assimilation of fo~ eign technology and increased market competition together with increasing c:~pability of local scientific and et~gineering personnel led 1~o the g~adual imp,ovement of foreign technology. Product improvement and cost reduction became an important b::sis for competitio~ not only in the domestic market but also in international markets which became ir- creasingly important. Indii;enous ef~'orts for technological change became important to improve products and to increase productivity, leading to a relatively more efficient, integrated and la~,~. 7 production system. In shorl, there seem to be three salient stages in the development of industrial

technology in the electronics ir~.iu'~tr'y in Korea: Implementation, AssimiL~- t~on~ and Improvement, nameo f c the predonfinant t echnol~ca l task ~f each stage. These three stages will b,, ~ exan~i,aed in more de~ail.

ported from abroad in the first year of production. This was also true in the

case of other electronic pro~lucts introduc,:d during the same period. Simple

parts were quickly prod~ced localIy as the finished products created the mar..

ket for tt'e parts industry; ho~vever, ~-oore ~'.ompiicated pat 's were imported

fro~., overseas. The prodaction process patt~::rn was inefficient because of low labor costs and

little cost pressure in the l:,rotected market. No data are available tbr the

1960s, but low labor cost is evident in a study conducted in 1970 which

found that hbor costs accounted for only 5.1% of toto.i costs o f a 19" black

and white TV set, which requires a relatively labo, in~ e.nsive assembly opera-

tion [9]. This implies low labor costs relative to other input faclors, possibly

suggesting that low labor pro:luctivity may not be problematic to manufac-

turers in this stage. The ana~!¢sis of data collected iin this stqdy fiom 31 pro-

ductive traits shows that c,perations technol,_~,y rigidity of Hickson et al. [8] * is positively correlated (r = 0.36, p <'. 0.05) with indigenous technologi-

cal capabifity.** The operations technology rieidity refers to the degree of ri- g~dity wiI:hin the production process whereby inputs are converted into out-

puts. A high degree of rigidity indicates a system-like, efficient process, while

a low degree of rigidity indicates a loose!y org::nize0, ineflic~ent process. The indigenous technological capability refers to the degree of i~digenous capabi-

lity of local firms ~ developing new products and is significantly related to the age of the productive umts tinder study (r = 0.50,p < 0.001), indicatiqg

that those at the early stagt have !ow indig, r, ous technological capability and

Thus, the indige~ous technc, logica! ":apab~lity was used h~ this st'ady as a .~ur-

rogate to measure technological d.:velopment stage~. To recapRulate, the

above relatiolzship indicates ~a,: productive units ~t this stage tend to have

more loosely organized, inefficient production processes thaa those in the

text.* The degree of influence on technological change was theh related to the degree of indigenous technological capability in an attempt to identify how a set of external influences change over different stages of industrial technology development. Thus, an inverse correlation, as shown in table 1, indicates environmental subco,~ponents that are perceived influential in technological change by productive anits at the early stage of technological development, while a positive correlation indicates those subcomponents that are perceived influential by productive units at the later stage of development. G,avernment and multinational ~irms were important sources of external influence on technological development in this stage. Table 1 shows that indigenous technological capability is inversely related to import and export policy, government incentives for technological change, law material suppliers. equipment suppliers, and technology suppliers. It indicates that these environmental subcomponents wer perceived as significantly affecting technological change in products and processes by productive units with a low deglee of indigenous technological capability at the implementation stage. In other words, government policy was a major influence in this stage in two ways: first, the t-ansfer of foreign technology establishing the industry occured when the government implement;.~d import substitution and market pr.r~lecti- on policies and second, various government incentive programs were atso perceived as important stimuli for technological change by industry. And multinational firms played an important role in establishing the industry as suppliers of technology, technical personnel, capital, equipment and compcment parts.

ASSIMILATION

Once product design and production tecnnologies transferred from overseas were successl{'ully implemented at several productive units, ,~;uch technologies were quickly diffused within the country. Fig. 1 shows tha', by 1975, 14 productive units ~,ere in the black and white TV market. 11 in the radio communication eqt~ipment market, and 10 in the electronic cMculator market. However, those productive units that entered the marke" later were not established through the international tran.~;fer of 'packaged' technology, but

Duncan [3], m his study of the external environment for manufacturing and R&I) organizations in the U.S., suggests, as the task environment, five. • components: customers, suppliers, competitors, socio-pditical, and technological. Each component has several subcomponems with the total of 13 altogether. The rationale for 20 subcomponents in this study can be found in [12].

through the transfer of local entrepre~~eurial and technical personnel from ex- isting productive units. 10 out of the 14 TV producers, six out of 11 radio communication equipment producers and 6 out of 10 etectroni,z calculator makers are in this category. The mobility of experienced technic,'d personnel was evidently the major mechanism for the diffusion of production technology within the country. When several productive units (established either through the i~ternational transt;er of technology or through its diffusion within the country) produced a similar product within the same market, the result was noticeable competition ~mong them. Under such conditions ea,,+h productive unit diversified its product to satisfy the needs of the different segments of the market on one hand and to obtain a bigger share of the ma:ket on the othcr hand. For in- stanc~'., productive units that began TV production in the mid-1960s entered the market with one or two" different 19" triodels. By 1970, five producers carried 18 different kinds of 19" sets in addition to 9", I6", ![7" and 23" modells [10]. Product diversification became the prevailing marketing strategy during this stage. This pattern of competitive strategy required indigenous efforts for the assi-

milatfon of foreign technologies in order to produce differentiated products. At the same time, competition, not only in the domestic marl:et but also in the i~Lternational market which was becoming increasingly important, led to more pressure to reduce costs by the manwfacturers. While the foreign experts workin:~ in the recipient productive units played an important role in the short-term implemelltation of imp(>rted technology in the first stage, local technical pe~'sonnel trained at the technology supplier firms played an important role in t':e asshnilation of foreign t:'chnology, and produJct and process development. "lechnical emphasi~ in this sl age was placed upon engineering and limited development (E&DI, rather than research. The f!inished product Lqdustry created a local market for the Farts industrie,.

Local components and parts manufacturing units emerged ,,vi+hin or outside the finished product manufacturers in response to the local demand, many throu?,h the int:~.rnational transfer of production tec!mology. :~esistors, capacitors and speakers were locally manufactured soon after AM r:~dio sets were first assembled locally. TV picture tubes and tuners were first n',a~]e in Korea thlough tlae international transfer of production technology four years after black and white TV sets were first assembled. A+ shown in fig. ], the pa+t substitution rate for TV sets rose from less than 30% in 1966 tc 50% by 1909 and to over 90% by 1975. A similar pattern was also observeci, as shown in fig.3, in electronic calculators, radio communication eqtfipnv:nt and other p~oducts.

Like the finished product industry, the rapid development of the local part industry can be largely attributed to the government's import subs:~" .,tion policy. The government ,~ncouraged l ucal fi,ms to develop ;~ supplier base by providing credit at preferential interest rates. More importantly, imports were only allowed if the user provided evidence of inferior or insufficient local supply. These measures have prompted finished product producers t¢~ integra- te backwardly or to assist local suppliers to assure themselves of a reliable source of supply at competitive prices. In short, the emergence of tile local parts industry was a ,characteristic of the Assimilation stage or the finished product. Tile growth of the electronics industry also provided a stimulus for the developn:ent of industrial machinery and mz~chine tool industries. Equipment al~d machine tools previously imported were gradually substituted

by local prodv.cts. On the basis or local market experience and in response to stimuli from OEM~; (original equipment manufacturers) and other overseas buyers, and to incentives of the g¢ vernment export promotion policy, many pr3ductive units developed export markets. The government played a majo~ role in the export expansion. Tt, e Electronics Industry Promotion L~iw of 1969 was aimed at develop:ng the indusUy as an export oriented industry. Long term loan at low ioterest rates, duty free for production maclthlery, accelerated depreciation.

and overseas marketing research service were among governn~ent programs that were designed to facilitate export expar, sion. That is, export promotion

was g];adually emphasized not only as an individual productive unit's growth strategy but also as a national po~ic.v. Fig. 4 shows the increase in the percen-

tage of exports to the total pro:lu,:tion of selected electronic products between 1965 and 1975.'For examT~le, while TV ptoduclion increased from

10,000 sets in 1966 to over 1 milh.:,n sets in 1975, tile percentage of exports

to the total TV production rose t rom 2% in 1968 to over 50% in 1975

(5,1 l) .

But not all exports grew from production to saisfy local demands. Some ne~

products were introduced in this stage in response to tile o~erseas market de-

mand before a sizeable local market ,,as created. For example, previous ex-

port experience and trade contacts established earlie led to tile production of

electronic calculators in Korea solely in response to the growing uverseas market demand. The local market for this oroduct developed slowly as seen in

fig. 4. Tape recorder and electronic digital watch production also showed a si-

milar pattern. In summary, once the elecuonics industry was established and

general production technology was widely diffused and accumulated, export markets became not only a source of stimulus for further development of the

izidustry in ~terms of size and technology, but also a source of stimulus for the develc,.pmem of new product lines solely for overseas markets.

Development of fltdt, strial technology 267

What are tqe external sources that influence the pattern in this stage? As ira- petted tecmologies were diffused and competition Built up in the local as well as the international market, sources of external influences for technological change in products and plocesses gradually shifted from those of government and multinational firms to those of cons',mers, distributors, and competitors. Table 1 shows that indigenous technological capab'lity is positively re-

lated to domestic distributors, domestic consumers, domestic fund suppl,~ers, local and everseas competitors, and competitors for supply. It indicates that these environmental subcomponents were perceived as significantly affecting technological change in products and processes by productive units with a high degree of indigenous technological capability. In other words, caanging needs of domestic consumers, custom orders of overseas distributors and original equipment manufacturers became important sources of stimulus for new product design and development at this and subsequent stages. New products introduced by competitors in and outside the country also became an important source of new ideas in this stage. However, none of the technological subcomponents was a significant source of external influence. This is not sur- prising. Since technology for products (e.g., radio, TV. low price stereo sets, calculators, watches, communication and broadcasting equipment, and simple testing instruments) produced in this inaustry and their processes was widely and generally known, new technological advances in and outside the country, higt- technological capability available at local R&D institutions, or systemati-

cally indexed information on recent technological development were not sig nificantly related to imitative changes in the industry.

and to finance increased imports, export expansion of locally manufaclured products was an impo:rtant alternative avail~.ble for obtaining tile necessary foreign exchange to settle the international balance of p~tyr~euts. For this reason, export p~omotign has become a national economic development polic,: for Korea. This forced productive units to enhance their competitiveness in international markets through imitation of more sophisticated foreign pro- duets and improvement of foreign ~l:echnology. This is what is currently taking place in some product lines in the Korean electronics industry. Although specific 'unpackaged' technologies may be imported from abroad, local RD&E (research, development and engireering) efforts have also become a necessary course of action for local industry not only to improve imported technology, but also to implement their own novd ideas. Thus, re- .search as well as development and engineering gradually became im.portant in this stage. No reliable data .ire awafiable on the ~ndustry wide R&D budget, but productive units under this study showed substantial R&D efforts. 21 out of the 31 pr,~ductive units had a s,zparate k&D departmev, t. These 51 organizations reported an average of 5.28 product changes per year in the past five years. ~ r e complete coverage of ~he innovativeh~:s of the=,: organizatic,ls i~ presented in another report [ 13].

As indicated previausly by the positiw. • correlatior~ between operations tecJ~nology rigidi:y and indigenous t~chnological capability, production processes which were gener',dly inefficient in the earlier stages had to gradually become mort~ efficient and integrated. Many productive units at- tempted to introduce industrial engineering aud production management techniques to rationalize production processes. Fig. 5 shows the production scale increase of the electr,,aics industry between 1961] and 1975. The average annu~l production value per productive unit mcrea.,;ed almost four times from US$5.8 million in 1970 to IJS$22.4 milli:,n in 19';'5, Productivity per worker all~o increased, as shown in fig. 2, about 2.3 tl,ues from US$3,600 in 1970"to US$8,340 in 1'975 [11]. Furtherm~bre, successful assimilation of foreigji technology throug~a accumulated experience in prod:~ction and product design and limited efforts in local R&:D activity led to the application of imported technologies to different product lines. For instance, a productive unit which impoarte~ foreign technologies to produce radio communication equipment designed a custom-ordered electronic quality control device for the government's cigarette plants.

Techno- logies lbr SSB (single side band) transreceiver and fish finde~s were applied to the production of broadcasting transmitters ot various frequency bands and powers and to radar [15l. Electronic calculator technology a,~d the technical assistance of local applieu research institutes are currently leading to the es- tablishment of minicomputer and microprocessor production in Korea. That is, not all the product line~ went tic, rough the Impleme-,*ation stage no:ed earlier. Assimilation of various foreigr, technolagies, increasing capability of local scientific and teclmica! personnel and loca: P.&D efforts provided a basis for general technological deveiopment of the industry and for introduction of more st~ptdstit, ated product lines without transfer of foreign technology. Exlernal influx, aces that we~'e increasingly importanz in the Assimilation stage became, as indicated in table 1, the most ~mportant sources of stimuli for technological change in this s~age. Changing needs of consumers or users and i,~forrnation from distributors provided crucial market information that led to the creation t~f new prodJct ideas. The competitor's inn;Jvative behavior caused many other firms to follow and adopt sh'nilar technologies.

Development of industrial technology 271

lead Korea to a position where its te :hnological capabili:y will b,e a challenge. to other industrialized countries in the world.

What were initial cor~dFions that made this pattern of development possible in Korea? Several factors seem to have played a signiticant role in the initial stage. Major factors include, among other things, the government's develop-

ment policy, availability of local ertrepreneurs and skdled technicians and engineers. An aggressive and balanced government development strategy that

started with import substitution poicy created a protected local market by restricting imports and provided various incentive programs to induc~: import substitution productions. There wele lecal entrepreneurs who knew how to

put foreign capilal and technology and local human resources together to exploit a new bu?iness opportunitie:, in the protected market. There was also an abundant supply of highly skilkd labor force, that quickl?/ learned and assimilated prodl~ct design and production techniques. That is, aggressive investmenls in education during the postwar period provided an important base for the subs~quent industrialization process. The evidence also indicates that there is a high correlation in the 19th century between educational indices and the .,;peed w!lh which ildividual Western c~untries were able to adopt and modiiy Britain's new indushial technology [22]. It was also the local technical and entrepreneurial c:~pability that facilitated Japan's industrial development.

APPLiCABI LITV OF THE MODEL

The three-stage raodel developed above is on the basis of consumer and irJdus- trial electronics equipment manufac:uring industry in Korea. However, eviderce indicates that tae model also describes the development pattern of technology at least in such industries as electrical appliances, agri-

cultural machiner)~ and automobile ndustries in Korea. For instance, tilt' :tutomobile indust :y was first started in 1962 as an assembly operation of se~r,~-a:,sembled Japanese cars. The automobile assembly industry created a market ft~r the autoparts industry,* and import substitution of component part, has reached 38% in 1969, 62% in ~972 and 95% in 1975 [11,21]. With t roduction md design experience accumulated during this period and The d :velopment of the ;ocal autoparts indust~y, together will: the government's au omobile irldustry promotion programs, the automobile in-

The autoparts industry existed, in .~maller scale, even before 1960 to r,leet the in- creashag replacement demand for Lmported milita:y vehicles and t.,vilian motor vehicles rebuilt from military equipment [28].

272 t~. K h n

dustry introduced in 1974 the first car designed and manufactured in Korea. Furthermor,,', both the autoparts and automobile industries have recently expanded their markets to overseas. Taking all the evidence together, it can be tentatively concluded that the model may apply to many industries whose production requires a large number of components and parts.

r

The appli:ability of the model to process, parts or raw material industries remains to be seen. However, evidence indicates that chemical, pharmaceutical, steel, and ,,;ynthetic fiber" industries were anso established through the international tr~nsfer of production processes, product specifications, production knowhow, technical personnel and raw material. The growth of these industries led to the emergence of raw material and machinery industries. Subse- quent facil:ity expansion and improvement were carried out by local engineers and technicians with local equipment. Furthermore, successful assimilation of imported technology later led to the production of more sophisticated products without foreign assistance. Is the model also applicable to industries in other countries? Several studies conducted in other countries for different purposes provide u,,eful evidence. lndt~strialization in Japan evolved through a similar pattern. ~,t the national level, Shishido [23] divided the 100 year history of industrialization in Jalzan into four steps: (1) the primitive stage which fully relied on impo~:ed technology and foreign engineers, (2) the transfer of industr,~al activity from the government to private sectors, (3) the assimilation of imported technology,, and (4) the catching-up process to a,Jvanced countries. The industriai technology in the 1860s and onwards w~s wholly dependent on technology imported from Europe and North America. Technologies imported included not only 'plant, machinery and raw 1~aterial, but also foreign engineers and craf~:smen.

In the case of tex'tiles, ~he Japanese government est~b~.shed the first textile mill in 1872 with French technology and enginecrs. Such technology was dif fused quitdy within the country. By 1880, Japal,ese technicians experienced in the government plant were able to play :l pivotal role in establishing private spinnir~:g mills [23]. The expansion of the textile iudustry resulted in the emergence of the spinning machine industry in Japan The autoraobile industry in Japan also grew through a similar ! rt~cess. AI- tho~agh aitempts were made to develop military trt~cks after British and French models, the automobile industry in Japan can I:,e said to have started with an assembly operation of American Ford and GM passenger c:~rs in the 1920s. As:~,imilation of foreign automobile technology througJ~ product design ~nd prodttction experience led Japan to introduce its own ,uodel 11 years later [2711. Through the process of assimilation and improvement Japan be-

came one of the leading auto~ob,3e exporters in the world. Japan's post-war technologicz! recovery was also due to imported technology. Ozawa [20] noted that Japan 'icensed a great number of foreign technologies. Then, its export competitiveness during the 1950s stemmed from a successt'ul assimilation of foreign technology. And in the 1960s, further expansion of exports through enhanced competitiveness sprang from the improvement of acq:fired technologies tl-rough original research. To a certain extent, the United States aiso went through a similar pattern a century ago. The U.S. reverser the sequence of research, development and er, - gineering (RD&E); that is, iI started with practical technologies imo.rted from European countries, ant then slowly evolved into the present position of being able to afford subst~mtial research [19]. For example, the U.S. imported steam engine technology from the Great Britain in the late 18tl~ century. But through assimilatioa of British technology, American mechanical skills were well developed by the 1830s ~nd did not need to rely upon o~ imi- tate British models and techniques [22]. Baranson [!] also observed :hat Brazilian firms (excluding foreign subsidiaries) began manufacturing with assembly and packing operations and eventually extended into more intricate operations. Engineering was the initiating portion of the RD&E (researci~, development and engineering) spectrum read- ing gradually to more advance t development and research efforts.

DISCUSSION

This article provides a skeletal description of the development pattern of industri',d tecimology as it appe~ rs to have taken place in productive uaits in the electronics industry tn K )rea. It also provides similar evidence in other industries in Korea and other co,11tries. Many variables both at the industry' and national levels may, however, account for variations in the developmewl pattern o:" industrial! technology in different countries. The characteristics of production technology and market structure may be sources of variation aL: the

industry level Policy on expt)rt promotion and foreign inve,~tment, the avail- abi,ity of local entrepreneurs, the capability of the local scientific and engineering personnel, and the availability of natural resources may be important sources of variation at the national level. Nevertheless, the g, eneral pattern of development of industrial technology that proceeds from implementation of imported technology to assi,,~zilation and eventually to improvement the~:eof in order to strengthen competitiveness is evident in the history of manufac-

27'4 L. Kirn

turing industries in different countries. More definite conclusions as to what parameters determine what variations, however, require empirical investigati-

ons in cLifferent industries and in different LDCs. As mentioned earlier, this study is a distinct departure from previous studies. It provides a new framework and a base for formulating several tentative propositions, that can be researched in future, on the development process of in- dustria]~ technology in different LDCs. These propositions include: -New productive units are established through the transfer of foreign technology in the early period (called Implementation stage) and through the mobility of local technical and entrepreneurial personnel in the intermec7 ate period (called Assimilation stage). -Implementation of imported foreign tech'aology is most frequently perceived as an important technical task in the Implementation stage, assimila-

tion in the Assimilation stage, and improvement in the Improvement stage. -International transfer of technology occurs predominantly in the 'packaged' mode in the Implementation stage and in the 'unpackaged' mode in the Assi- milatie,n and Improvement stages. --International transfer of technology is a more frequent source of the generation of new technology than contractual research with local R&D institutions or internal R&D efforts in the lrrple~entation stage, wlfile internal R&D effort is a more frequent source them others in the Improvement stage. --Government measlJres to epsure local market protection (e.g., import substitution, control on foreign investment, etc.) are perceived as a most important source of stimulus for the generation t~,f a new technology in the Implementa- tion s~age, while government measares to ensure markcl co.npetition (e.g., export pron,otion, and anti-mon,~poly) are perceived as a most important source of stimulus in the Assimilat,,m and Improvement stages. -Hurr~an resources in greatest demand for the gene~tion of a new technology are foreign technical experts dispatched to the recipient productive units in ~the Implementation stage, local technical personnel trained at the supplier firm in the Assimilation stage, an,t local scientific and engineering persom el in the Improvement stage. -Larvae firms that have pre~rious trade com~ections 're more likely to generate

a new technology through the international transfer of techn~ I,~gy in the Im- plementation stage, while small firms ~ith technical entrepreneurs are more likel~ to generate a new technology th:t-ough itlternal efforts ill the Improve- ment stage.

-The degree of export orientation is positively related to the generation of new ~technology.

-An important role of local ,~&D institutions is consultation in the Imp!e-

mentation stage, adaptive Jevelopment in the Assimilation stage, and R&D in ~.he Improvement stage. - Diffusion of technology s predominantly through the international transfer of technology in the Implementation stage and through the mobility of local technical personnel between firms in the Assimilation and Improvement stages. -Production process technology is inefficient in the Implementation stage and becomes relatively m ~re efficient in the Assimilation and Improvement stages in response to increasing labor cost pressure.

-Multinational companies that supply capital, raw materials, and technology and Government ire the t',redominant sources of external h~fluence on tech-

nological change in the Implementation stage, while customers and competitors are in the Assimilatior and Improvement stages. -Emphasis of local efforts is on engineering (E) in the Implementation ~;tage, development ,and engineering (D&E) in the Assimilation stage, and research, development and engineering (RD&E) in the Improvement stage. -Comt~onents and parts are mostly foreign in the Implementation stage and

mostly local in the Improvement stage. Most of variables in the above propositions can be measured through e~.:ami- nation of records of government agencies, trade association, banks, and other secondary data sources and through interviews with managers. Three stages of technology development can be measured by either one of two surrogate nlcasures: part substitutien rate and indigenous technological capability. The study of Nabseth and R:,y [18] may be useful to developing a measure for diffusion of technology. In conclusion, the model '!~resented in this study explains the process of f!irm's behavior in a LDC in imlrorting, adapting, assimilating, a~d improving foreign technologies in response to the changing competitive environment and how internal and external factors affect this process. If the model becomes ger~er- alizable tluough subsequent research in differew, industries in different ,::oar~- tries at a similar development stage, it will provide usefu]l implication:~; not only for policy makers and managers of comparable countries, but also for those of other developing countries which attempt to follow the same path and for those of advanced countries in formulating interr~ational scienct:~ ax: :~

tethnology policy.
