Purpose - This paper aims to analyze the difference of technological innovative pattern by industry. Research design and methodology - we try to identify the major factors which can exert an effective influence on actual innovation output, utilizing the result of Korean Innovation Survey. By doing so, this work can make a comparison with Pavitt (1984) and succeeding discussion on sectoral pattern of innovation Results - Analysis on major industry in Korea shows that there are substantial differences in terms of the source of innovation, organization-related factor, and appropriation mechanism among each industry, and differential strategy to be proper for the nature of each industry is needed. There is some variation within industries which deemed as same type of sector defined by Pavitt. Conclusions - This analysis call for elaborate analysis on sectoral pattern of innovation, considering the change and difference of innovative environment as well as differential business strategy and way to do innovate, which is proper considering the nature of innovative pattern in each industry for successful technological innovation in Korea. At the same time, proper policy measure considering the differential pattern of technological innovation is needed.

본 연구는 미국 내 다양한 지역들의 소비위험 분산의 결정요인을 실증적 접근을 통해 분석하고자 한다. 이를 위해 미국 내 8개 경제권역의 다양한 조합을 소비위험 분산 집단으로 간주하고 거시, 금융변수의 통제 하에 해당 소비위험 집단들의 산업구조 편차가 각 집단의 소비위험 분산에 미치는 영향을 살펴보고자 한다. 본 연구의 실증분석 결과에 따르면, 소비위험 집단내 산업구조 편차가 심할수록 해당 소비위험 집단의 자본시장 경로를 통한 소비위험 분산은 더욱 활발해지는 것으로 나타난다. 이러한 연구결과는 지역 간 경제통합에 있어서 산업구조가 이질적인 지역일수록 자본시장을 통한 소비위험 분산 집단을 형성하는 경향이 강하다는 사실을 암시한다. 또한 본 연구의 실증결과는 현재 진행되고 있는 FTA나 여타 경제통합 진행과정에서 보다 효율적인 경제통합 달성을 위해 회원 국가 혹은 지역의 산업구조가 고려되어야 함을 시사하고 있다.

Purpose - This work tries to analyze the transformation of sectoral innovation pattern as time goes by to enhance the understanding on sectoral innovative activities, particularly considering the change of the nature of knowledge, and the trend of convergence. Research design, data, and methodology - This work tries to identify main factors, which determine the output of technological innovation through the econometric analysis, utilizing the result of Korean Innovation Survey and find a stylized fact on the change of the innovation pattern. Result - As a result of estimation, some major elements show different effects for two discrete years, 2002 and 2010; in chemical industry the open information source and neutral basic research become more important with the appropriation mechanism such as patents, and in machinery industry, the importance of internal information has been getting decreased with rising importance of customers. Conclusion - This work presents that some elements show different effects for two discrete years. Among three major elements, the source of information and appropriation mechanism shows different features for both industries. This means that we should explicit consider the changing nature of innovative environment, which leads to and heavily influence whether the innovative activity would be effective or not when we design innovation strategy and innovation policy.

This paper empirically investigates potential factors that might affect firms' incentives to license out technology. The analysis is done with the help of a panel data set of observed licensing transactions involving U.S. public companies in high-technology industries. The important explanatory factors relate to the firm characteristics such as the company's stock of technological knowledge (patent stock). prior involvement in technology licensing. the company size, R&D intensity and capital expenditure. The results suggest that there seems to be significant inter-sectoral differences as well as similarities in determinants of the propensity to transfer technology through licensing agreements.

기울어진 자전축을 갖는 회전계에서, 일정한 각속도로 회전하는 동서풍이 있는 경우에 대해서 로스비하우어비츠 파동의 섹터모드(적도에 대한 반구 비대칭의 첫 번째 모드)와 균형을 이루는 지위고도장을 해석적으로 유도하였다. 균형장은 발산방정식으로부터 시간변화를 제거하고 라플라시안 연산자를 역산함으로써 구하였다. 역산은 비선형항의 계산과 포이슨 방정식의 해를 구하는 두 단계의 연산과정으로 이루어져 있다. 두 번째 단계에서, 구면조화함수로 표현되는 강제력의 항은 구면조화함수의 선형관계를 이용하였고, 그 이외의 항은 구면조화함수를 적분함으로써 구하였다. 균형장은 여섯 개의 동서파수 성분으로 표현됨이 드러났다. 본 연구에서 구한 균형장은 적도에 대하여 비대칭의 구조를 가지기 때문에, 대칭의 구조만을 가지는 것에 비하여 미분방정식의 수치해의 검종법으로서의 활용도가 높다. 일정한 각속도를 갖는 배경 동서풍이 지구의 자전각속도와 같거나 1/2에 해당하는 경우에는, 일부 동서파수 성분이 제거되는 것으로 나타났다. 이론적으로 구한 균형장은 정교한 수치모델을 통하여 구한 균형장과 거의 정확하게 같은 것으로 밝혀져, 이론적 해의 타당성이 입증되었다. 마지막으로, 로스비하우어비츠 파동의 섹터모드와 균형을 이루는 지위고도장의 안정성을 장기간시간적분을 통하여 살펴보았다.

In this paper, we examine the points of similarity and difference between Korea, Japan, and the USA in terms of the spin-off effects of space technology on cultural life. In Japan and the USA, spin-off effects of space development research by government funded research centers are diffusive while in Korea they are interruptive. Spin-offs of research results impact cultural life via technology transfer and commercialization in businesses. This is because the Korean aerospace industry has progressed largely based on an overall system, but the promotion of internal parts and sub-systems, which can trigger technological development and spin-off effects in manufacturing, has been neglected. In the case of the KARI, the government funded research center, we argue that it is necessary for KARI to devote more resources to transfer (or promote spin-offs of) space technology to small and medium-sized businesses and other industries.

The main objective of this research is to examine the spillover effects of technological knowledge from IT industry to other industrial sectors and, based on empirical findings, to draw policy implications and suggest policy directions. To this end, we divide IT industry into IT equipment and IT service, assuming that these two sub-sectors are considerably different each other in terms of technology knowledge flow. Other industries are classified into 17 different sectors based on the KSIC of 1990. As the proxy measure of technological knowledge, the notion of R&D stock is employed. The Input/output(I/O) Table is used to define the inter-industrial flow pattern and to draw the knowledge flow matrix. As the research methodology, cost function model is employed to gauge the spillover effects of technological knowledge of IT industry. Based on the results of analysis, it is found that the economic impact of technology diffusion also exhibits a different pattern between IT equipment and IT service. The diffusion of IT equipment tends to show labor-substitution effect whereas IT service displays labor-creation effect. This fact should be considered in devising industry, education, and labor policy. The expectations from this research are as follows. First, the sectoral pattern, difference between IT equipment and service in particular, identified from this research may shed light on the sector-specific policy direction. It is emphasized that a sector-specific approach, rather than an aggregate approach, is relevant for formulating IT policy. Second, it is expected that the importance of technology diffusion programs and policy measures are recognized among policy makers in IT industry.

The way to respond to climate change is divided into mitigation and adaptation. So far, the response of climate change has been focused on mitigation. The perception of response of climate change also has been focused on mitigation. However, climate change mitigation and adaptation should be highlighted in a comparable concept as a response to climate change. On the other hand, perception of the public on climate change affects the support or opposition of the general public about climate change-related policies. The purpose of this study is to assess awareness of the general public and stakeholders on the subject of climate change adaptation and to present a basis for a future national climate change adaptation policy. Questionnaire on awareness of climate change adaptation were composed of the climate change and climate change response (mitigation, adaptation) understanding and importance, the seriousness of climate change-related adverse climate event, the need for climate change adaptation measures, the degree of implementation, and the level of government effort for climate change response. Climate change adaptation-related awareness survey was conducted for the general public 1,011 people and stakeholders 101 people by telephone interviews. In this study, the perception survey has a difference in aspect of the contents and methodology. And We were able to present the three characteristics of the general public and stakeholders aware of the subject of climate change adaptation. First, the relative importance of climate change adaptation was relatively low. Second level of awareness about climate change response of the public was significantly lower than the stakeholders. Finally, the need to prepare the implementation of the sectoral level, the first adaptation measures was relatively low.
