This paper empirically examines whether and how inward foreign direct investment (FDI) affected industrial productivity in Korea during the 2000-2016 period, based on dynamic panel data of inflow FDI on an arrival basis from 427 manufacturing industries. The paper adds to the literature by analyzing whether both technology spillovers and industrial restructuring from inward FDI can differ according to industrial characteristics such as capital intensity, imported intermediate inputs, and tariffs. The empirical results show that the overall effects of inward FDI on total factor productivity (TFP) were statistically insignificant in general. However, the positive effects of inward FDI on productivity became statistically significant for industries with lower tariffs. Capital intensity were not involved in the relationship between inward FDI and productivity. Thus, the paper highlights that the results in previous studies with inward FDI on a notification basis were overestimated and inward FDI policies in Korea should focus on channels such as trade liberalization and the redistribution of production factors rather than capital accumulation.

Given the substantial industrial and economic contributions of university start-ups, a growing number of studies have adopted the ecosystem perspectives to systematically explain creating start-ups in universities. Despite the huge theoretical potential, few studies have analyzed the complex, complimentary interactions of the core components in the university entrepreneurship ecosystems (UEEs). Addressing the limitation, this research not only discusses the role of the core ecosystem components, such as patents, entrepreneurship education, and student entrepreneurship clubs, but also analyzes their discrete and complimentary effects on the productivity of UEEs. Based on a national survey of universities, this study shows that all the core components have a positive effect on the ecosystem productivity. More importantly, this study investigated the complimentary relationships among components and tested the moderation effects of both the entrepreneurship education and the student clubs on the relationship between the patents and the productivity of UEEs. The analysis results show that the student clubs intensify the patents' positive effect on the productivity of UEEs. The research results could provide the crucial policy insights for the successful design of UEEs.

This paper investigates the effects of China's participation in global value chains (GVC) on the productivities focusing on the manufacturing industries. In this study, several indicators of participation in global value chains were used. These include GVC participation, forward GVC participation, backward GVC participation and GVC position index. In particular, we used the data obtained from 18 manufacturing industries in China during 15 years from 2000 to 2014. The main results of the analysis are as follows. First, the higher the degree of total participation in GVC, the higher the productivity. This means that with the increase in exports and imports of intermediate goods, productivity has increased through technology spillover effects or competition effects, and so on. Second, the backward participation does not increase the productivities significantly while forward participation leads higher productivity. Third, the productivity improvement effects of GVC participation was larger in the high-tech industries than in the low-tech industries. These results show that GVC participation was helpful for the economic growth of China and the efforts for moving toward upstream production stage in GVC is necessary for the improvement of international competitiveness in Chinese manufacturing industry.

This study determines whether or not firms can achieve high productivity growth through external technology acquisition. It also identifies the key factors affecting adopting firms' productivity growth by employing the Malmquist productivity index (MPI) methodology, which features computational ease, low data dependency, and decomposition of productivity growth into technical efficiency change and technical change. Results showed that the effects of productivity growth arising from technology transfer became stronger over time. Moreover, patent transfer guaranteed firms' productivity growth, but no evidence was found that factors such as age and size could increase productivity. Finally, cultural similarity could be another factor conditioning the effectiveness of technology transfer in the productivity of adopting firms.

The importance of information technology (IT) has been emphasized in developing countries recently. Despite the importance of the topic area of the productivity of IT in developing countries, the literature to date is relatively sparse. The findings of almost all these studies are based on data collected in developed countries. Few studies have been conducted to validate these results and to see if they are still applicable in developing countries. This study tries to investigate the effects of IT investment on productivity in the electronics industry of China, which is a representative developing country, with production function model. The results show that there is a positive impact of IT investment on productivity in China similar to previous studies in developed countries.

본 연구는 1991년~2005년의 기간 동안 한국 특허청에 출원된 내국인 특허의 공동발명자료를 이용해 네트워크 특성 변수들의 '연도별 x 발명자별' 패널 자료를 구축하고, 이 자료를 사용하여 발명자 네트워크의 특성변수들이 발명자의 특허생산성에 미치는 효과를 패널 회귀분석하였으며, 다음과 같은 결과를 얻었다. 첫째 네트워크상의 강한 연계는 발명자 생산성에 정(+)의 효과를 미치는 것으로 나타났다. 둘째, 네트워크내 중심에 있는 발명자일수록 특허생산성이 높았다. 셋째, 네트워크의 기술적 다양성은 발명자의 특허생산성을 높이는 요인이다. 넷째, 발명자 네트워크의 질이 좋을수록 그 네트워크에 속한 발명자의 특허생산성이 높아진다. 다섯째, 네트워크의 크기가 클수록 네트워크내 발명자의 특허생산성이 높다. 여섯째, 네트워크에만 의존하는 발명자의 특허생산성은 상대적으로 낮았지만, 네트워크에 속하지 않은 발명자의 특허생산성은 오히려 높았다. 일곱째, 네트워크 변수들의 효과는 지역별로 차이가 있다. 여덟째, 지리적 경계가 약화되고 있지만, 네트워크 효과의 지역적 차이는 줄어들지 않고 있다.

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.

A genetic improvement program in Korea was implemented to improve the performance of Hanwoo cattle by generating livestock with genetically desirable economic characteristics. In particular, in response to external changes, such as the expansion of Free Trade Agreement (FTA), the livestock genetic improvement program has increased farm income by improving the productivity and quality of Hanwoo cattle. Using production cost data from Statistics Korea, the total input and output indices of Hanwoo feeding cattle from 2008 - 2021 were estimated and the growth and productivity changes were analyzed. The productivity change measures results were used to estimate the cumulative effects of the Hanwoo genetic improvement program on quality improvement, another purpose of the program, using a finite distributed lag model. The average annual increase in output (market weight) of Hanwoo was 0.9%. However, total input increased by 1.6%, resulting in a 0.6% decline in total factor productivity. In contrast, the Hanwoo genetic improvement program contributed significantly to the production of high quality beef, rather than contributing to improved productivity of the cattle. Hanwoo carcass weight, which is used as a performance indicator for the livestock genetic improvement program, has significantly improved and is projected to increase at a slower rate. The collective findings indicate the need for new performance indicators that can comprehensively indicate the performance of the genetic improvement of Hanwoo.
