This paper starts out by reviewing the literature that in different ways utilizes patent data as a output of R&D investment. The main focus, however, is an analysis of time-lag between R&D input and output. To achieve this research objective, the basic data associated with the R&D input(expenditure, researchers) and output(patent, utilities) for the past 15 years, from 1980 to 1994, in the areas of electrical-electronic, mechanical and chemical industries have been collected. And the raw output data were altered it to objective data using Laspeyres approach and analyzed using multiple regression analysis, especially stepwise regression analysis. The result of this study can be summarized as follows: a) The time-lag between R&D input and output is from 1 to 4 years. This result is equal to the research conclusion of the existing foreign studies. b) It was found that the time-lag of patents was longer than of utility models. c) It was showed that the time-lag of electrical-electronic, mechanical industry was longer than the chemical one.

This paper is aimed at analyzing the effect of Information Technology (IT) investment on the output growth and Total Factor Productivity (TFP) of Korean stock industry. Data on 24 stock firms for the eleven years (1991-2001) are used for the analysis. It is identified that there are both direct and indirect impacts of IT investment of the Korean stock industry on output growth. The total effect on output growth is 1.34 percentage point per year, which divided into a direct effect of investment in IT on the output growth is 1.97 and an indirect effect on the TFP is -0.63 percentage points per year. Results show that IT investment cannot contribute to increased stock industry productivity. Therefore, the Korean stock industry has not benefited from increased investment on IT in increasing productivity, implying the so-called productivity paradox has existed during the period.

This paper starts out by reviewing the literature that in different ways utilizes patent data as an output of Research ＆ Development (R&D) investment. The main focus, however, is an analysis of time-lag between industrial R&D input and its output. To achieve this research's purpose, the basic data associated with the industrial R&D input (expenditure, researchers) and output (applied patent and utilities) for the past 15 years, from 1980 to 1994, in the areas of electrical-electronic, mechanical and chemical industries have been collected. And the raw input data were altered into real flow data (but stock data) using Laspeyres approach and analyzed using multiple regression analysis, especially stepwise regression analysis. The result of this study can be summarized as follows: a) The time-lag; between industrial R&D input and its output is within 1 to 3 years. b) The time-lag: of patents was longer than that of utility models. c) The time-lag: in electrical-electronic, chemical industry was longer than that of the mechanical industry.

Competitiveness of a nation can be explained by the concept of national innovation systems(NIS). As components of NIS, industry clusters become the issue in analysing innovative activity of an economy. Innovative clusters can be identified by the innovation survey or other economic activity data. Input-output Table was used widely as a tool for quantitative analysis, This paper classifies seven clusters in Korean industry based on inter-industries trade of intermediary goods and services, Maximizing procedure method is used in analysing input-output table. Identified clusters are Textiles/chemicals, Construction/Material, Instrument/Equipment, Automobile, Services, Energy, and Agriculture/Food cluster, Among these clusters, some different characteristics in R&D portfolios are detected. R&D investment characteristics of each cluster give us significant implications in understanding innovative dynamics of Korean industry.

본 연구는 정부 R&D보조금의 정책적 효과를 규명하기 위해 투입, 관리, 후속, 인지부가성이 산출부가성에 미치는 영향을 규명한다. 또한 투입, 관리, 후속, 인지부가성과 산출부가성의 관계에 대해 정부 R&D보조금 수혜 경험의 조절효과를 분석한다. 실증분석을 위해 연구개발특구 입주기업 중 연구개발특구육성사업에 참여한 경험이 있는 기업을 대상으로 설문조사를 시행하여 수집한 126개 기업의 응답 자료를 분석하였다. 분석결과 투입, 관리, 후속, 인지부가성과 산출부가성의 관계는 모두 긍정적 효과가 있는 것으로 확인되었고, R&D보조금 수혜경험의 조절효과에서는 투입효과성(R&D보조금 ${\times}$ 투입부가성)과 인지효과성(R&D보조금 ${\times}$ 인지부가성)에서 긍정적인 조절효과를 확인하였다. 추가적으로, 종업수가 많을수록, 업력이 낮을수록, NT와 ST산업에서, 첨단기술기업일수록 산출부가성에 긍정적인 영향을 끼치는 것으로 나타났다. 본 연구를 통해 그 동안 국내에서 진행되지 않았던 미시적 관점의 행동부가성에 대한 실증을 실시하여 국내 혁신클러스터 단위에서 투입 행동부가성과 산출부가성관의 관계, R&D보조금 수혜경험의 조절효과를 새롭게 규명하였다.

The explosion in creation and utilization of IP including Patent since 1980s has been regarded as typical trend affecting the environment for technological innovation. Korea also has shown massive creation of IP. These stimulate the focused interest on the effectiveness of IP for protecting the innovation output. We try to analyze the determinants of this effectiveness in Korean manufacturing sector in terms of the charactenstics of firm's innovation strategy. It is shown that, for protection for product innovation, as being larger, and as having made innovation, the IP protection is regarded as effective, and firms making cooperative R&D have a higher possibility of using IP protection. And larger firms give a higher recognition to effectiveness of IP protection irrespective of the types of innovation such as product innovation and process innovation.

The research shows how the technological change of 'Information and Communication Technology' (ICT) is accompanied with the usage change. It aims to provide a better conceptualization with empirical findings about the fact that the technological development of ICT is a convergence process of ICT factors with the usage of ICT moving from a limited coverage toward a general-purpose. The research adapts a descriptive methodology on a historical matter and demonstrates how it can be conducted through analytical description of Input-Output tables (I/O) the over periods. The case is about the UK with sequential I/O during 1970s- 90s.

본 논문에서는 소자 결합 구조를 통해 발진전력이 합쳐지는 회로를 이용한 저전압, 고효율 Q-band MIMIC 발진기를 제안한다. 0.1 ㎛ GaAs PHEMTS와 CPW 전송라인을 사용하여 제안된 구조의 발진기를 성공적으로 집적화하였다. 제작된 발진기는 34.56 ㎓ 주파수에서 2.6 ㏈m의 출력 전력일때 19 %의 높은 효율특성을 가졌다. 이때 회로에 인가된 전압은 2.2 V로 현재까지 Q-band에서 발표된 발진기보다 낮은 구동전압 특성을 얻었다. 또한 최대 출력 전력은 34.56 ㎓ 주파수에서 6.7 ㏈m을 얻었다.
