The purpose of this study is to analyze the effect of the R&D subsidies by the government on the private firms' R&D investments in the Korean pharmaceutical industry, which are supposed to have positive effects on their economic performance. We also estimate the relationship between the private firms' R&D investments and firms' economic outcome. Empirical analysis is done by Error Component 2 Stage Least Squares(EC2SLS) estimation using 43 pharmaceutical firms' 8 years' panel data. The elasticity of the government R&D subsidies on the private R&D investments is 0.021%, which we cannot say 'efficient'. Also R&D investments have positive effects on the economic outcome of the pharmaceutical firms, as we expected. We propose several suggestions in the conclusion for the efficient way of government R&D subsidies to induce more private R&D investments.

An analysis of the railroad industry for R&D investments has been insufficient whereas there are lots of analysis of accumulation of technology, economic performances and ripple effects for macroscopic view and other industry of R&D investments. This study decided intellectual rights, patent, and paper as common indicators of scientific and technological performances for setting up performance targets through surveying and analysis of preceding study and verified a appropriateness of scientific and technological performances for railroad R&D 11 projects which were successfully finished. Preceding study has been set up performance targets by research investments as input, but this study made a performance target by model through a cross-sectional and residual analysis of performances of railroad R&D 11 Projects in applying research investments, capital investments, inner labor cost and inner labor cost per man and research time as inputs, and verified a validity and a empirical analysis through analysis of other project.

This article describes a methodology for evaluating huge aerospace R&D investments using the real options pricing method. Option pricing has been proposed as a useful approach for modeling investment in R&D. Two important features of R&D investments are that an R&D project takes time to complete and that the outcome of R&D investments is highly uncertain. This makes the analysis of R&D investments difficult. Traditional tools for project evaluation, like IRR or the NPV, are inadequate for coping with the high uncertainty. Hence, In this article I propose a log-transformed binomal lattice method, and it will show that option pricing might be an adequate framework for evaluating such types of aerospace investments.

This paper investigates the effects of various R&D investments on economic growth empirically. To this end, the relationships between various R&D investments and economic growth are analysed, and the rates of return of R&D investments are estimated. Furthermore, the effect of government R&D investment on private sector R&D investment, and the effect of social factors, which affect the relationship between the R&D inputs and economic growth, are analysed. Based on the results of this analysis, a simulation model is developed, which shows the relationship between R&D investments and economic growth rate; this model is verified by analysing the correlation between the actual and the estimated economic growth rate, using the data between 1981 and 1995 of eight selected countries. The validation results show that the simulation model has sufficient accuracy to be used for evaluating and proposing R&D policies for the countries for which appropriate data is available. However, the time-lag effect, which is naturally believed to exist between the R&D input and the economic growth, could not be analysed in a mathematical form, because of the lack of the data to establish this relationship. Thus, when estimating the relationship between them, the time-lag effect in this relationship was included implicitly by using the data of fifteen years.

본 연구의 목적은 국내 제조 산업의 R&D 투자가 산업의 제품경쟁력과 원가경쟁력의 증대를 통해 높여 수출에 미치는 영향을 살펴보는데 있다. 이를 위해 한국 제조업을 대상으로 20개 업종별로 2004년-2014년도의 자료를 이용해 실증분석 하였으며, 산업의 제품 경쟁력을 신제품 혁신역량과 품질경쟁력으로, 산업의 원가경쟁력을 노동생산성과 자본생산성으로 나누어 살펴보았다. 경로분석을 통해 검증한 분석결과는 다음과 같다. 첫째, 제조 산업의 R&D 투자가 증가 할수록 산업의 신제품 혁신역량, 품질경쟁력, 노동생산성, 자본생산성이 증가하였다. 둘째, R&D투자로 증대된 제조업의 품질경쟁력, 노동생산성, 자본생산성의 향상은 수출 증가에 긍정적인 영향을 미쳤다. 따라서 한국 제조 산업의 R&D 투자는 품질경쟁력과 원가경쟁력의 강화를 통해 산업의 수출 증대에 긍정적 효과를 미친다는 것을 확인하였다.

Considering the recent substantial increase in national research and development (R&D) budgets in the energy sector there has been increased Interest in the effectiveness of government R&D investments. We conducted a case study to calculate the allowable scale and effectiveness of R&D investment by calculating the direct performance improvement effect resulting from R&D investment as an economic value. Using conditions that existed prior to R&D investments as a reference, five cases in which performance improved due to R&D investments were compared and analyzed. The government's financial investment is increasing rapidly in line with the establishment of the national hydrogen roadmap. R&D is needed to enhance the current low technology readiness level of hydrogen fuel cells compared to solar and wind energy fields. Therefore, an R&D project to improve the performance of the fuel cell system was selected as this case study's subject. Using the results in this study, the allowable level of investment in the task unit of national R&D projects could be calculated. Moreover, it is advisable to provide a standard for rational decision making for new R&D investments since it is possible to determine investment priorities among a large number of candidates.

R&D 투자와 경제성장간의 관계에 대한 많은 기존 논의들은 R&D 투자가 경제성장에 대해 강한 양(+)의 관계가 존재함을 제시하고 있다. 그러나 투자와 성장사이의 강한 결합관계가 반드시 일방적 인과관계를 의미하는 것은 아니기 때문에 인과관계의 방향에 대한 보다 심층적인 연구가 필요하다. 특히 급변하는 안보환경 속에서 국방 R&D 투자가 증대되고 있음을 고려해 볼 때 국방 R&D 투자와 타 부문 R&D 투자 및 경제성장과의 결합관계에 대한 논의에 앞서 각 변수들 간의 인과관계에 대한 연구가 선행되어야 하나, 현재까지 국방 R&D 투자와 타 부문 간의 인과관계를 연구한 실적이 전무한 실정이다. 따라서 국방 R&D 투자와 다른 변수들과의 인과관계 분석을 통하여 국방 R&D 투자정책에 관한 정책적 시사점을 제시하였다는데 본 논문의 의미를 두고자 한다.

그동안 정부는 R&D투자의 성과 제고를 위해 R&D 시스템 내의 구조와 프로세스를 개선하는데 많은 노력을 기울여 왔다. 그러나 대내외 기술 환경이 급변하고 투자규모가 지속적으로 증가함에 따라, 정부 R&D 또한 다양한 외부자원의 활용을 통해서 규모의 수확을 이룰 수 있는 혁신적인 접근방법이 필요한 상황이다. 이러한 관점에서 '개방형 혁신'은 외부자원에 대한 흡수능력 (absorptive capacity)을 향상시키고, 다양한 혁신주체 간 협력과 참여를 제고시킬 수 있다는 점에서 '정부실패'의 가능성을 최소화 시킬 수 있다. 본 논문은 정부 R&D투자의 성과에 관한 선행연구와 정부정책을 평가하고, 개방형 혁신이 정부 R&D투자의 성과 제고에 기여할 수 있는 연계성을 보여주고 있다.

This paper examines the effects of intellectual property protection policies on upstream firms' R&D investments in order to derive policy implications in relation to the fostering of the intermediate goods industry. To that end, the dependence on import of intermediate goods and the degree of protection of intellectual property rights are introduced into the model to analyze the effects of R&D investments on the dependence on imports and the effects of intellectual property rights protection policies on the level of R&D investments in order and the social welfare effects are also checked. The policy implications derived in this paper, which used an oligopolistic market model with a vertical specialization structure, are as follows. As R&D investments expand, upstream firm begins to have price competitiveness, the dependence on import of intermediate goods by downstream firm decreases, and social welfare increases. That is, in order to strengthen the independence of the intermediate goods industry, R&D investments by upstream firm should be expanded, and to promote this, the government should strengthen the protection of intellectual property rights.

This study analyzes various factors affecting a firm's investments, focusing on both a firm's ownership structure and CEO's incentives. While previous empirical works focus on various financial data in order to test the Schumpeterian Hypotheses, this paper is using various ownership structure data as well as financial data. Empirical results show that the greater a firm's CEO has the company's own stock, the less he spends in R&D investments. The main empirical results of this study is in line with past empirical studies on various markets outside of Korea.
