본 연구에서는 산업의 혁신패턴이 기술체제에 좌우된다는 산업별 혁신체제론적 접근에 따라 산업의 기술체제 특성이 지식전파와 혁신성과에 미치는 영향을 분석하였다. 과학기술정책연구원의 "2008년 기술혁신활동조사: 제조업"DB 자료를 이용하여 기술체제에 따라 산업을 분류하고 계량모형을 이용해 지식외부성의 원천과 지식전파가 유발하는 기술혁신을 산업별로 분석하였는데, 주요결과는 다음과 같다. 첫째 특수적 암묵적 지식기반 산업에서는 일반적 명목적 지식기반 산업과 달리 기업의 혁신성과가 입지특성으로부터 영향을 받는 것으로 나타났으며, 고기술-특수적 암묵적 지식기반 산업에서는 연구개발자본이 풍부한 지역, 저기술-특수적 암묵적 지식기반 산업에서는 동종산업의 집적도가 높은 지역에 입지한 기업일수록 제품혁신이 활발하였다. 둘째 제품혁신을 선도적 혁신과 추종적 혁신으로 구분하여 지식전파가 유발하는 혁신수준을 산업별로 알아보았는데, 저기술산업에서는 외부로부터 전파된 지식이 선도적 혁신과 추종적 혁신을 유발하고 고기술산업에서는 추종적 혁신만 유발하는 것으로 나타났다. 이와 같은 분석결과로부터 지식외부성의 원천과 지식전파가 유발하는 기술혁신의 수준은 산업의 기술체제에 따라 다르며, 지역산업 클러스터정책은 산업의 기술체제 특성을 감안해 모색할 필요가 있다는 함의를 얻고 있다.

Firms prefer in some specific conditions cooperative R&D to non-cooperative for developing technology. Previous studies on the conditions show firms want to choose cost-sharing type of cooperative R&D (the CS-RJV) rather than non-cooperative one when target technology is either 'relatively easy'or 'relatively difficult', and to join multiple-research type of cooperation (the MR-RJV) than to compete each other if technology is only 'relatively easy'. However, by introducing technological spillover as well as difficult of technology, only if there shown that this seemingly contrasted phenomenon almost disappears : the MR-RJV can i3e also preferred by firms even in case of 'relatively difficult'technology only if there exists some extent of a technological spillover.

This study evaluates the economic impact of product innovation by using firm-level data from the Community Innovation Survey conducted in Japan. It accounts for possible technological spillover from innovation activities and examines the extent to which new-to-market product innovations contribute to firm performance. Econometric analysis using a simultaneous equation model reveals that new-to-market product innovation is likely to increase a firm's sales without cannibalizing those of existing products and generate more technological spillover to other firms. Moreover, such innovation is more likely to emerge from firms collaborating with academic institutions. The paper concludes by discussing policy implications of these findings as well as points to the importance of cross-country comparison between Korea and Japan.

Using patent and firm-level panel data for 1982-2001, this study investigates spillover effects of patents and the strengthening of intellectual property rights on Productivity and Innovation. As well as we consider the effect of intra-industry spillovers, we extend the effect to inter-industry spillovers which implies the effects of IT industries on non-IT industries. The empirical results are summarized as follows. First, allowing for firm-level variables, market competition and technological spillovers, the strengthening of intellectual property rights does not play a significant role on innovative activities. Second, while innovative activities of domestic firms affect significantly firms' innovative activities, those of foreign firms do not. Third, innovative activities of IT industries as inter-industry spillovers play a significant role on innovative activities and labor productivities of domestic firms.

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.

This paper aims to develop a conceptual framework for determinants of spillover effects of FDI on technology innovation of Vietnamese enterprises. The research proposes a logistic regression model for assessing how enterprises' ability to implement technological innovation is affected by the presence of FDI enterprises as well as other factors that show the change through the indirect influence of FDI such as the size of the enterprise, the type of enterprise, and the skill level of the labor force or its research and development activities. Five forms of technology innovation are considered: improving production process; product quality improvement; product expansion; expanding business activities into a new field of production; and changing business activities into a new field of production. General Statistics Office of Vietnam provided survey data to collect information from 3,166 enterprises in the manufacturing and processing industry in Hanoi, which were valid for analysis. The results show that all variables of enterprise type, size, R&D, and industry have a positive impact on the selection of one of the innovation forms. Several recommendations are further suggested to take advantage of the positive effects and minimizing the negative effects of FDI for technological innovation of Vietnamese enterprises.

Technological innovation generates products, services, and processes that can disrupt existing industries and lead to the emergence of new fields. Distributed ledger technology, or blockchain, offers novel transparency, security, and anonymity characteristics in transaction data that may disrupt existing industries. However, research attention has largely examined its application to finance. Less is known of any broader applications, particularly in Industry 4.0. This study investigates academic research publications on blockchain and predicts emerging industries using academia-industry dynamics. This study adopts latent Dirichlet allocation and dynamic topic models to analyze large text data with a high capacity for dimensionality reduction. Prior studies confirm that research contributes to technological innovation through spillover, including products, processes, and services. This study predicts emerging industries that will likely incorporate blockchain technology using insights from the knowledge structure of publications.

The study empirically examines the horizontal spillover effects of foreign direct investment (FDI) on the productivity of Indian pharmaceutical firms. Robust least squares and the Generalized Method of Moments estimators are applied for the firm-level panel data of Indian pharmaceutical companies whose shares were traded on the National Stock Exchange (NSE) and Bombay Stock Exchange (BSE). The information was collected from the Centre for Monitoring Indian Economy (CMIE) Prowess database from 2015 to 2019. Based on the regularity in data availability, the sample firms are limited to 112 companies, 100 of which are domestic firms and 12 international firms. Firms with more than 10 percent foreign equity are classified as FDI firms, while those with less than that are classified as domestic firms. Estimation results show that foreign ownership does not contribute to the productivity of domestic firms. Due to increased competition, the Indian pharmaceutical companies with foreign equity participation are not more productive than local ones. Moreover, the findings reveal a negative and insignificant horizontal spillover effect from FDI on the productivity of domestic enterprises. The absence of horizontal spillovers may be attributable to foreign enterprises' ability to prevent technological outflow to competitors in the same industry.

이 연구는 국가경쟁력을 향상시키는 조건으로서 기술창업의 역할에 대해 분석한다. 기업가의 지식확산이론(Knowledge Spillover Theory of Entrepreneurship)을 기반으로, 국가 내 기술기반 창업의 비중이 국가경쟁력을 높이는 데 어떠한 영향을 주는지 분석한다. 또한 국가경제개발 단계 측면에서 혁신주도형경제(Innovation-driven economy)에 해당되는 경우 국가경쟁력에 미치는 기술창업의 영향력이 어떻게 조절되는지 살펴본다. 2011년부터 2014년까지 83개 국가의 기술창업, 국가경쟁력지수, 경제개발단계 등의 데이터를 기반으로 분석한 결과, 국가 내 기술창업비율은 국가경쟁력과 U자형 관계를 가진다는 점을 확인했다. 또한 국가 발전단계 상 혁신주도형경제에 해당되는 국가의 경우 이 관계는 강화되는 방향으로 조절되는 점을 확인했다. 이 연구는 기술 기반의 창업 비율이 증가할수록 국가경쟁력에 무조건 긍정적 영향을 미치지 않으며 상황과 조건이 잘 맞아야 함을 강조한다.
