외국인투자유치를 통해서 지역발전과 경제성장을 이루려는 목적으로 도입된 경제자유구역이 2003년 본격적으 로 도입된 지 20년이 넘었다. 그동안 경제자유구역 연구는 주로 정책적인 측면에서 이루어졌다. 경제자유구역에 실제로 투자한 외국인투자가 시각에서 한국의 경제자유구역이 어떻게 받아들여지고 있는가를 정확하게 평가하는 것이 필요하다. 이에 본 연구에서는 인천경제자유구역 송도지구에서 장기간에 걸쳐서 투자와 경영활동을 성공적으 로 수행하고 있는 4개의 외국인투자기업(삼성바이오로직스, 셀트리온, 얀센백신, 아이센스)에 대한 사례분석을 통 해서 경제자유구역에 대한 심도 있는 평가와 경제자유구역 발전을 위한 정책적 시사점을 도출하고 있다. 본 연구 에서는 더닝의 해외직접투자 절충이론 ‘OLI 프레임워크’를 적용하여 사례를 자세히 분석하고, 경제자유구역 관련 정 책적 시사점을 도출하였다. 본 연구 결과 외국인투자가의 다양한 기업특유우위(Ownership specific advantage) 를 확인할 수 있었고, 각 사례 기업이 중요하게 평가한 인천경제자유구역의 다양한 입지특유우위(Location specific advantage)도 파악할 수 있었다. 100% 지분율의 얀센백신 사례에서는 내부화우위(Internalization advantage) 를 확인할 수 있었으며, 소수지분으로 투자한 나머지 사례에서는 한국기업과 파트너가 되어 협력적 투자를 실행한 동기도 확인할 수 있었다. 본 사례연구 결과로 도출된 정책적 시사점은 첫째, 외국인투자유치에서 결정적인 역할을 한 양질의 토지를 확충할 경제자유구역 추가 지정, 둘째, 경제자유구역 내 외국기업 단독 또는 협력 등 다양한 방식의 연구개발 사업에 대한 지원을 확충 등이다.

This study analyzed whether there are mediating effects of government policies between the inputs and the economic performances of Korean bioenergy companies-this was accomplished by applying a mediating analysis by PROCESS Macro ver 2.16.3 (Hayes, 2013) based on a survey from the bioenergy companies. The analysis found that the increase in inputs of the Korean bioenergy companies affected the increase of performance through the government policies. In addition, comparing the mediating effects of detailed policies, this study found that said effects were greater in the order of RPS(Renewable Portfolio Standard) > the price variation of electricity = the obligation of greenhouse gas reduction > the changes in business scale based on RPS·RFS(Renewable Fuel Standard). However, it was found that the price variation of transportation fuels and RFS did not make a significant difference. There are two political implications of this study. First, to enhance the economic performance of bioenergy companies, the Korean government should keep the expanding trend of the current RPS. Second, the government needs to emphasize the importance of biofuels for transportation and make policies to develop related industries.

The study aims to analyze economic of biogas plant in transition of recognition that waste resources has become renewable energy. The traditional investment valuation method using the NPV or IRR has a limitation in a sense that uncertainty of the future is not reflected. Hence, the purpose of this paper is to assess the value of the business by taking advantage of the real option. Biogas plant simulation is applied to the case of Garak Market using the binomial options among a variety of real options. With this analysis, it is assessed that operational expand option is the largest of the value of the binomial options.

The production of bio-energy crops is a major research project in the emphasizing the “low carbon ․ green growth” strategy. For this, the possibility of the introduction of the new energy crops improve the agricultural income from farming must be diagnosed. This study describes the level of agricultural income per unit area by cropping system based on the income of crops in the field. Especially, we have chosen the southern part attracting the attention in the possible area of the bio-energy crop production. This study consists of five chapters. Chapter Ⅰ is the introduction. Chapter Ⅱ is on the status of the southern part cropping system and the analysis of the economic value. Chapter Ⅲ is on the economic value analysis introducing new bio-energy crops. Chapter Ⅳ is on the comparative analysis for the economic value of the croping system introducing new bio-energy crops. Chapter Ⅴ is the conclusion.

This study evaluated economic feasibility to find a method that can increase income of a rape farmer for biodiesel. Biodiesel is one of an important bioenergy that can be used to substitute diesel-fuel. A rape is useful not only for biodiesel, but also for a substitute of a barley. This study deals with the income and cost data of a rape farmer compare to that of a barley farmer. According to the result of economic evaluation from 2002 to 2006, the income of a rape farmer for biodeisel incurred a loss. However, this study showed that the income of a rape farmer would be approximately 80% of that of a barley farmer if a new variety of rape called ‘SUNMANG’ was growed. Also, biodiesel has various ancillary effects such as by-product, preservation of a scenery, reduction of CO2, etc. If the income of a rape farmer had ancillary effects, it would exceed the income of a barley farmer. As a result, we need to support ancillary effects of a rape to encourage a rape farmer for biodiesel.

The objective of this paper was to evaluate economic feasibility of biodiesel production. Biodiesel is a diesel-fuel replacement produced from domestic renewable resources such as vegetable oils. This paper deals mainly with the income and cost data to analyze economic feasibility of biodiesel. The income of a rape farmer for biodiesel was 206,894won/10a, and it’s similar to barley income. In addition a rape production for biodiesel have ancillary effect. Therefore we have to use direct payment for encouraging the production and use of biodiesel.
