  • 본 연구는 기술혁신파급경로를 결정하는 국가 간 무역역할에 대한 실증적인 분석을 목적으로 한다 이 연구목적을 위하여, 최근 자료인 1980년부터 2003년까지 15개 OECD국가를 대상으로 자국의 기술혁신을 결정하는 중요한 변수로 알려진 자국 R&D축적 및 무역대상국의 R&D축적자료를 구축하였으며, 이를 무역지수인 쌍방간에 수출 및 수입량을 경제규모로 나눈 가중지수를 이용하여 유입된 R&D축적량을 구축하였다. 또한 대상변수들의 기술혁신파급역할에 대하여 최근 논의되고 있는 비정상적 패널기법을 이용하여 분석하였다. 최근 제안되고 있는 비정상적 패널기법을 이용하여 국제 간에 기술혁신파급경로를 분석한 결과를 간단하게 요약하면, 다음과 같다. 첫째, 분석대상변수들은 비정상성을 갖는 것으로 나타났다. 둘째, 그러나 장기적으로 분석대상변수들이 서로 균형상태를 나타내는 공적분관계에 있음을 알 수 있었다. 셋째, 국가 간에 기술혁신파급경로의 방향과 정도를 파악하기 위하여 패널 공적분계수를 추정하였으나, 설정함수형태에 따라서 여러 가지 상반된 실증결과가 나타났다. 따라서 기존 연구Coe et al., 1995, Keller, 1998, Kao, et al., 1999 그리고 Funk, 2001]의 분석결과 및 그 시사점들이 서로 다른 이유는 분석대상변수들의 선택차이뿐만 아니라, 기술혁신경로에 대한 설정함수형태에 따라서 서로 다른 분석결과가 나타날 수 있는 가능성을 보여준다. 본 연구에서 나타난 분석결과의 시사점을 보면, 국가 간에 기술혁신파급경로분석은 기술혁신파급을 결정하는 매개변수선정도 중요하지만, 결정된 설명변수들 사이에 어떤 기술혁신파급에 관한 연관관계가 존재하는지에 대한 실증분석 즉 파급경로분석도 매우 중요함을 보여준다. 이러한 파급경로분석에는 기존의 선형가정뿐만 아니라 비선형가정을 이용한 기술파급경로분석을 통한 시사점제안이 요구된다.관적인 시스템을 제공하는 것이다.가 생성된다. $M_{C}$에 CaC $l_2$를 첨가한 경우 $M_{C}$는 완전히 $M_{Cl}$ 로 전이를 하였다. $M_{Cl}$ 에 CaC $l_2$를 첨가하였을 경우에는 아무런 수화물의 변화는 발생하지 않았다. 따라서 CaS $O_4$.2$H_2O$를 CaC $O_3$및 CaC $l_2$와 반응시켰을 때의 AFm상의 안정성 순서는 $M_{S}$ < $M_{C}$< $M_{Cl}$ 로 된다.phy.

  • As the trade linkages and the financial relationship between China and Korea grow stronger, China's influence on Korea is also growing larger. Therefore, it is meaningful to examine key features of Chinese monetary policy operations and the current situation, and to analyze the transmission mechanism of China's monetary policy shocks onto the Korea economy. China's monetary policy shocks can have an impact on the Korea economy through the trade, financial and oil-price channels. In the trade channel, an expansionary Chinese monetary policy can increase Korea's exports of intermediate goods to China under the vertical trade structure, via the vertical trade integration effect. Meanwhile, the expenditure switching effect and the income demand effect show no statistical significance. In the financial and oil-price channels, expansionary Chinese monetary policy shocks can decrease the interest rate and increase both stock prices and the consumer price index in Korea through changes in global portfolio capital flows, interest rates, and raw material prices.

  • This study examines the degree of global co-movement & spillover effect among the housing price of ten major countries of OECD including Korea, based on the 3 hypothesis. The data used in this study is quarterly house price index of OECD countries from 1975 to 2012. VAR model is used to analyze the co-movement, and Granger causality methodology is used for the analysis of Spillover Effect. It is found that entire period of study is that the global house prices showed the co-movement, but the coefficient was weak. Since 2008 global financial crisis, the co-movement increased significantly and the adjusted R-square of this model increased 78% compared to the entire period (1975-2012). In general, all hypotheses in this study were significant, and the common shock hypothesis were most significant. In case of Korea, the degree of co-movement was weak compared to the other countries and spillover effect was independent since 2008.

  • This paper reviews the theoretical background of the entrepreneurship policy recently prevailing in Korea. First of all, we define the entrepreneurship policy as the one that the government increases the supply of the individual entrepreneurs with entrepreneurship and supports their venture creation activities by intervening the entrepreneurial process. We distinguish the entrepreneurship policy from the small and medium-sized enterprises policy and the venture firm policy. As for the legitimacy of the entrepreneurship policy, we introduce the market for entrepreneur, examine the factors resulting in the market failure, and argue the necessity and the principles of government intervention to the market. Based on the entrepreneurial process, we establish the framework of entrepreneurship policy and examine the transmission channels by the policy area. The channels are (1) demand side, (2) supply side, (3) decision-making of establishing a new firm, (4) resources obtaining. Lastly, according to the transmission channels, we classify various entrepreneurship policy tools being presently implemented by the Korean government. However, since this study is a exploratory economic analysis of entrepreneurship policy, the approach and contents of entrepreneurship policy can be varied according to the research agenda and policy intension.

  • The anatomical study of whole organ sections was used necessarily for understanding the histopathological anatomy, and routes of neoplastic spread. Ten whole-organ cancerous larynges were axially sectioned and its histopathologic findings were compared with the MRI findings. This study is designed to evaluate the anatomical relationships of the tumor to the laryngeal structure & possible spread of cancer of the larynx.

  • In this paper, we present a literature review of the mechanisms and methodology for technology spillover, in order to provide a theoretical and practical foundation for estimating the technology spillover effect of public funded R&D programs. Our research consists of four parts. First, we investigate what technology spillover is and how it works. Second, we review the methodology used to empirically measure technology spillover, with a view to understanding the advantages and disadvantages of each method. Third, we identify the gap between the spillover phenomenon and its estimated results, caused by the limitations of the methodology, and discuss the challenges in measuring technology spillover. Finally, we present several considerations to improve the measurement of technology spillover in the context of public funded R&D programs. Our paper provides policy makers and researchers with basic knowledge about technology spillover and helps them suitably evaluate the results obtained from the literature review. In addition, it contributes towards improving the existing methodology by recognizing the gap between the spillover phenomenon and the methodology.

  • Social-impact is getting more emphasized for the R&D program evaluation. Qualitative indicators such as 'Productive-interactions' and 'Social-impact of R&D' have been included for the evaluation criteria in USA, UK and Netherlands. Recently, Korean government also realizes importance of the social-impact, so 'Follow-up evalution' is launched in order to evaluate not only technical-impact but also social-impact. In this paper, possibilities and challenges of social-impact analysis are reviewed. Furthermore, successful cases from the leading overseas countries are benchmarked to have policy implications.

  • This paper develops a framework for analyzing the effectiveness of broadband network from the value chain view. The value chain of broadband network is composed of activities such as broadband network building, application/equipments development, information systems utilization. The effectiveness from the interaction between these activities are defined as the effectiveness of informatization(private and public sector) and the effectiveness of IT Industry(effects on production on inducement of broadband carriers, IT equipments and service market creation, online digital contents market creation). For testing its real-world applicability, a case study is performed on the broadband network of Korea and the effectiveness of the framework for analyzing the effectiveness of broadband network is demonstrated.

  • This paper investigates how oil price changes have an impact on the Korean manufacturing production activities. For this investigation, we use a structural VAR motel to estimate impulse response functions of industrial production, producer price and export price to an oil price increase over manufacturing industries. It finds that in most manufacturing industries, an oil price increase leads to decreases in industrial productions and domestic prices except energy intensive industries, but to increases in industrial export prices except non-metallic (26), computers and offic machinery (30), electronic components, radio, television and communication (32) industries. This result explains that an oil price increase makes negative impacts on the manufacturing production activities not only through demand slowdown in the domestic markets but also through supply contraction in the export markets.
