이 논문은 Carlsson and Stanklewicz(1991)가 창안한 기술시스템(technological systems)의 개념을 한국과 스웨덴의 산업용로봇에 적용하여, 양자를 비교 분석하고자 하였다. 먼저 기술시스템의 개념을 재구축하고, 동태적인 측면에서 시스템의 진화과정을 보강한 다음, 한국과 스웨덴의 산업용로봇에 대한 기존 연구를 활용하여 양 기술시스템의 중요한 특징들을 비교하고 그 성과를 측정하였다. 한국과 스웨덴에 있어서 산업용로봇 기술시스템의 진화과정은 공히 미국, 일본 등 기술선도국을 모방하는 입장에 있었음에도 불구하고 '학습기간'이 20여 년 이상 소요됨을 보여주었다. 뿐만 아니라 양 시스템의 진화과정. 특히 태동기(embryo stage)에 있어서 정부의 역할이 매우 컸던 것으로 분석되었다. 그러나 기술시스템의 구성요소인 산업네트워크, 기술하부구조, 그리고 제도적하부구조 면에서 강약점 및 특징의 차이가 있음을 발견하였다. 기술시스템의 동태적 성과면에서는 한국의 경우가 스웨덴의 경우보다 상대적으로 더 우월한 것으로 평가되었다. 이는 스웨덴 시스템에서는 초기에 우위를 누렸던 기계, 전기, 그리고 메카트로닉스 기술의 우위와 사용자 능력이 점차 약화되어온 반면에 한국의 시스템은 기술하부구조 등이 취약하였지만 해외시스템과의 연계, 재벌 내에서의 기업간 연계, 산학연 협동, 그리고 지역내 연계 등 시스템내의 연계성이 기술적으로 취약한 부분을 보전해 주었기 때문인 것으로 분석되었다. 따라서 어느 한 기술시스템이 자생적으로 생명력을 이어가기 위해서는 시스템 구성요소의 개별적 형성 및 발전보다는 구성요소간 그리고 시스템내의 다양한 활동주체들의 상호작용과 연계성이 중요함을 강조하였다.

In this paper we： (1) analyze the relationship among public R＆D investment, private R＆D investment, and GDP by employing the Clangor causality test; (2) examine if there is any country-specific pattern in the relationship by testing the cases of Korea, the U.S. and Japan. We found some common results for the above countries as follows： (i) GDP causes Public R＆D, not vice versa; (ii) Private R＆D causes GDP; and (iii) Public R＆D does not cause Private R＆D. For the bivariate model of GDP and total R＆D, the results show the existence of one-way causality running from total R＆D to GDP f3r both U.S. and Japan. We also found bidirectional causal relationship between GDP and total R＆D for Korea, which could be interpreted as a typical pattern for newly industrialized countries.

Evaluating the sources of economic output is obviously important, and numerous attempts have been made to judge the impact of many different factors on economic output. It is widely accepted that high-technology(HT) is one of the important factors in economic output. This paper empirically explores the impacts of HT exports on economic output using a cross-county analysis based on data from 89 countries for the year 1988-2000. To this end, several versions of the neoclassical growth models, explicitly including HT exports, are estimated. Subject to the appropriate caveats, the results provide further support for several key conclusions of the former studies - investment in physical capital, population growth, and the human capital are important in accounting fer economic output across countries. More importantly, it is concluded that HT exports significantly contribute to economic output. Interestingly, the conclusion is valid f3r developing countries, but not far developed countries.

본 연구는 대덕벨리 벤처기업들의 현황 분석을 목적으로, 벤처 기업들의 CEO들을 대상으로 설문조사를 실시하였다. 이를 토대로 의미미분법을 적용하여 심층 분석해 본 결과, 대덕벨리의 벤처기업들은 대체로 자금조달, 마케팅 전략, 그리고 네트워크에 문제가 있는 것으로 나타났다. 특히, 제한된 자금조달 원천, R＆D에 치중한 기업 전략, 낮은 산학 연간 협력구도가 핵심 현안문제로 제기 되었다.

This paper tried to evaluate an economic analysis about research and development far areas of renewable resource in Korea. To evaluate this validity, we tried to calculate the spillover effect of R＆D investment through input-output table. In the first stage of spillover effect, we simply calculate the rate of return on R＆D investment for renewable energy resources in Korea through the input-output model, which can calculate the value added as well as output based upon the price of 2000 year. According to the first stage calculation, the rate of return on R＆B investment in solar heat is higher than any other renewable energy. In the second stage we tried to calculate the second round of spill over effect, which derives from the additional amount of supply of renewable resources due to the R＆D investment. The overall evaluation of R＆D invesment including the first stage as well as second stage spillover effect shows that bio-energy and waste energy generate 14 times as well as 2.5 times in the rate of return respectively.

This paper examines the change of innovation practices in the Korean industry which is entering into the 'post catching-up regime'. In catching-up regime, the technological loaming practices of Korean firms could be characterized as the assimilation and improvement of foreign technologies through crisis construction and time pressure. Crisis construction and time pressure were the important factors enhancing the intensity of technological teaming and shaping the way of doing imitative innovation. But the innovation patterns of firm are changing. The new ways of doing innovation are emerging in Korean mobile phone industry which is becoming a world leader： the emphasis on the importance of technological planning, the enhancement of collaborative networks among related firms, the toleration on the failure and the effort to acquire core technologies. Though Korean firms have not developed enough capabilities to create basic core technologies, they can develop their competitiveness through creative combination of technologies and are approaching the world frontier.

In year 2003, the Daedeok Science Town(DST) has celebrated its 30 years of anniversary and achievement in science and technology development. However, there is a criticism that DST has not played its expected role in Korea's National Innovation System. Recognizing this criticism, the development of DST was evaluated in the perspective of innovation cluster. The research shows that DST has been following the downstream path of evolution - from S＆T development to business development - and is in the early stage of R＆D-driven Innovation Cluster. Not only the development factors of DST innovation cluster were identified but the DST was compared with other internationally recognized innovation clusters. Finally, it is suggested that the business related functions should receive due attention in innovation cluster policy.

The importance of maritime sector in Korea has been increasingly recognized in recent days. As the country enters the $\ulcorner$new ocean era$\lrcorner$ the oceans are often regarded as holding the keys to solve the problems of modem industry associated with changing environment as well as changing societies and national politics. This paper attempts to address the national maritime R＆D policies and their relative importances. In the methodology, Saaty's analytic hierarchy process model is used to evaluate and rank the selected maritime R＆D projects which have a wide range of characteristics and policy implications. The criteria used for policy evaluation relates specifically to the Korea's evaluation needs and culture, and those criteria are weighted according to their relative importance as perceived by the maritime R＆D specialists.

There are many new technologies developed these days and the companies try to assess their technologies in order to either get financial supports or verify how valuable they are. However, since not only so many innovative technologies have been developed, but also the areas are very diverse, it becomes really difficult to value the technologies by the conservative technology valuation systems. Especially, in the energy technology area, it is much harder because energy technology is mainly used for public purposes and there have not been many experiences of valuing technologies. In this paper, the objective and systematic technology valuation system tool for energy technology will be suggested and investigated.

이동망의 착신접속서비스는 각국에서 bottleneck 서비스로 인식하고 규제당국에서 원가에 근거하여 규제하고 있다. 원가에 의한 규제 방식으로 과거에는 회계자료를 근거로 한 역사적 원가가 사용되어 왔으나 최근에는 유선망의 경우처럼 bottom-up 방식의 장기증분원가(Long Run Incremental Cost ： LRIC)를 적용하는 사례가 증가하고 있다. LUC를 산정하기 위해서는 공학적인 기준에 따라 이동망을 설계하여 정확한 망 구성요소별 소요량을 측정하고 이를 투자비로 전환하는 작업이 필요하다. 유선망의 경우는 LRIC산정을 위한 망 설계방법론이 비교적 잘 확립되어 있으나, 이동망의 경우는 망 설계 및 망 구성요소별 소요량 산정방법론에 대한 연구가 부족한 실정이다. 본 고에서는bottom-up방식의 이동망 LRIC산정관련 해외 사례를 살펴보고 국내 실정에 적합한 이동망 설계 방법과 망 구성 요소별 소요량 산정 방법론을 제시해보고자 한다.

As the high-speed internet access market steadily nears its maturity phase, growth is quickly tapering off and competition, intensifying. As a result telecommunications companies are at present faced with the urgent need to evolve away from a growth model based on continuous acquisition of new subscribers. The recent convergence of telecommunication and broadcasting has come about precisely at this transitional period in the telecommunications market, and is perceived by the industry both as a new business opportunity and as a threat. TV-based VOD(Video on Demand), for one, is able to attract new customers desiring multimedia services of superior quality and to lock-in existing customers. Meanwhile, the latest evolution in network development is brightening the market prospect for TV-based VOD. The service has now hit the market, deployed over VDSL networks - a next-generation high-speed internet - and advanced cable modem networks, delivering high-definition DVD-quality videos. TV-based VOD is a service whose deployment is closely linked to the evolution of subscriber networks. According to the forecast produced by the present study, based on the forecast on the post-ADSL market and a survey conducted on VOD, as post-ADSL subscribers increase from 1.53 million in 2003 to 4.44 million in 2004, and 9.87 million in 2006, the percentage of post-ADSL subscribers with intention to also subscribe to a VOD service is expected to rise from 16% to 34% in 2006. Accordingly, VOD subscribers are estimated to increase from 0.24 million in 2003 to 0.98 million in 2004 and to 3.35 million in 2006.
