This study analyzes whether the network characteristics lead to differences in innovation performance between inventors, using the case of Samsung Electronics and Hyundai Motor Company which have applied for the most patents in the electronics and automobile industries while showing significant differences in the degree of collaborative invention. The more inventors an inventor is connected with in the network, the higher innovation performance is achieved. While existing literature addressed intra- / interindustry, and intra- / inter- group spillovers at the organizational level, this study extends this discussion to the inventor level. This study newly introduces spillover pools from network components and then constructs spillover pools in three dimensions of the group, the industry, and the network component. The study analyzes the effects of each spillover pool on invention performance of an individual inventor and compares the effects between spillover pools. At the inventor level, the innovative effects of spillover pools were confirmed. The results of this study suggest that the inventor's network characteristics and spillover pools can be used to predict the inventor's innovation performance.

어느 국가를 막론하고 전략기획과 경제적 파급효과의 평가 모두 공공연구 프로젝트를 효율적으로 관리하기 위해 이루어져야만 한다. 기획과 평가는 공공연구에 있어 핵심 관심사가 되어 이러한 활동을 증가하게 만들었고, 기업에 대한 관심도 커지게 되었다. 처음에는 공공연구의 특성과 결과에 대한 정보교환과 효과적인 관리를 위한 도구로 경제적 파급효과 연구를 수행했으나 지금은 연구개발 투자에 대한 결과의 타당성 확보의 중요한 자료로 활용되고 있어 이에 대한 관심은 점증하고 있다. 본 연구에서는 주로 미국의 NIST(National Institute of Standards and Technology)에서 개발하여 적용되고 있는 CEM(Counter-factual Evaluation Model : 가상현실 평가모형)을 소개하고 이를 실제 공공연구과제에 적용하여 경제적 파급효과를 분석하였다.

This study is to investigate the expenditure patterns that was generated by visitors who attended The Korean Music Wave Festival and analyze economic impact derived from that event. The target is the foreign visitors who attended '2011 Incheon Korean Music Wave'. Total of 407 questionnaires were collected. The collected data were analyzed to produce spending patterns using Tobit models. Also, tourism multipliers were employed to identify the economic impact. This results show that expenditure determinants such as demographic variables and satisfaction as independent variables are significant in estimating visitors' expenditures. Also, In addition economic impact derived from direct spending was substantially over committed cost. Accordingly, this result can contribute to providing basic information for marketing strategy that generates the economic effect on the destination. Moreover, the result can be utilized when establishing the strategy that can maximize the economic impact based on the spending patterns.

Recent efforts of government to improve economic performance and increase employment through industrial convergence are being promoted actively. However, unfortunately, we have little of quantitative study on the following questions; (1) what is the rate of industrial convergence progressed?, and (2) what is the rate of total effects of industrial convergence spreaded?, and (3) which is the No. 1 industry in the magnitude of inductive effect of industrial convergence? In this study, we have measured and analyzed quantitatively the following questions using patent citation; (1) how is industrial convergence progressed?, and (2) how much has industrial convergence a effect on all industry?, and (3) what is the rate of the inductive effect of industrial convergence? In doing so, decision about industrial convergence has been made using patent citation and the effect of industrial convergence is drawn from convergence I/O table which made by patent citation.

The media industry is becoming more important around the world and there are changes over this industry. Therefore this is the time that the economic impacts is needed about media industry. This study attempts to examine the economic impacts of the media industry using an inter-industry analysis. Specifically, the study investigates production-inducing effect, value added inducing effect and employ-inducing effect of the media industry based on demand-driven model and the study deals with supply shortage effect and sectoral price effect of the media industry by using supply-driven model and Leontief price model. The results of this analyses are presented; 0.5461 won in production-inducing effect, 0.3143 won in value added inducing effect when 1 won is produced by media industry, 5.0459 persons in employ-inducing effect when 1 billion won is produced, 1 won of supply shortage in this industry results 0.7353 won in supply shortage effect which affect the other industries. Sectoral price effect is 0.2389% due to the 10% increase of price.

The government is planning to expand the bio-gas supply as a method for mitigating greenhouse gas emissions to deal with climate change. By means of a policy instrument, the government is considering an introduction of the Renewable Fuel Standard (RFS) whose targets include bio-gas. This paper attempts to look into the economic effects of expanding the bio-gas supply by applying an input-output (I-O) analysis using a 2011 I-O table. The bio-gas supply sector consists of liquefied petroleum gas supply sector and city gas supply sector, based on the tenets of introducing the RFS. The production-inducing effect, value-added creation effect, and employment-inducing effect of the bio-gas sector are analyzed. The supply shortage effect and the price pervasive effect are also investigated. The results show that the production or investment of 1.0 won in the bio-gas supply sector induces the production of 1.0539 won and the value-added of 0.1998 won in the national economy. Moreover, the production or investment of 1.0 billion won, supply shortage of 1.0 won, and a price increase of 10.0% in the bio-gas supply sector touch off the employment of 0.5279 person, 1.6229 won, and an increase in overall price level by 0.0183%, respectively.

This paper considers the technology spillover effects on industries by analyzing patents. Registered patents in the United States from Korea in 1990 and 1995 are compared by quantity of registrations as well as patent analysis indices, namely, cites per patent, technology cycle time and science linkage. Several regression models between these indices as predictor variables and the value added of an industry as a dependent variable were investigated. The results show that the value added of an industry positively correlates to the number of patent registrations and cites per patent.

Many countries are committed to absorb foreign direct investments (FDIs). One of the strong motivations is the improvement of innovative capability through the technology spillover of FDI firms. The effect of FDI technology spillover has been widely researched not only on country level, but industry level. With the evolution of globalization and global sourcing of multinational companies, it is necessary to reexamine the relationship between innovation ability of an industry and spillover effect of FDI. This paper investigates the technology spillover effect of FDI on the innovation of Chinese firms. We gathered the data of 34 industries form various sources of Chinese government and the time span is 2001-2008. By using industry level panel data, we set panel data analysis model. In the model, there are two explanatory variables: backward and foreward integration. The analysis result shows that technology spillover of FDI has significant effect on the innovation of foreward integration FDI.

This paper attempts to conduct a comparative analysis on the economic effects of integrated-energy and manufactured gas supply sectors. To this end, an input-output (I-O) analysis is applied using most recently published 2011 I-O table. In particular, the two sectors are specified as exogeneous to identify the economic effects on own and other sectors. Production-inducing effect, value-added creation effect, and employment-inducing effect are quantified based on demand-driven model. Supply shortage effect and price pervasive effect are analyzed employing supply-driven model and Leontief price model, respectively. The results show that production-inducing effect, value-added creation effect, and employment-inducing effect of integrated-energy and manufactured gas supply sectors are estimated to be 1.5461 vs. 1.0297, 0.4759 vs. 0.1941, and 2.2885 vs. 0.4053 respectively. Price pervasive effects of the 10% increase in integrated-energy and manufactured gas supply sectors are computed to be 0.0127% and 0.1585%, respectively. This information can be utilized in forecasting the economic effects of introducing integrated-energy or manufactured gas as a heating source and the impacts of a rise in price of integrated-energy or manufactured gas on price level of other sectors.
