Using a panel data set covering 19 Korean manufacturing sectors for the period 2009-2015, this paper investigates the extent to which industry characteristics affect the mode of entering foreign markets. The estimation results across various specifications show that firms prefer affiliate sales to export as firm heterogeneity increases, implying positive effects of productivity regarding foreign relative to domestic operations. The motive for overseas production is reinforced as economies of scale at the plant level decrease and economies of scale at the corporate level increase.

This study analyzed the effects of housing wealth on the balance accounts of elderly households with an age of over 60 facing the asset decumulation period, capitalizing upon an ordered logit model for the 2011 household finance survey data. Out of some variables representing personal and social characteristics, the age and waged worker variables had a positive effect, but the number of household, low education level, living in the apartment and capital region variables negatively affected the balance accounts of elderly households. Some variables reflecting economic wealth and financial strategies such as the attitude of risk-taking, ordinary income and the ratio of financial assets had a positive impact, but other variables such as DSR did a negative one on the balance accounts of the elderly households. The ownership of housing wealth variable positively, but the ratio of housing assets variable negatively affected the balance accounts of the elderly households, which could be derived from the duality of housing as both consumption goods and assets. However, the ownership of other real estates and the ratio of them in the total assets variables had a negative impact on the balance accounts of the elderly households. Furthermore, since the financial asset-debt ratio worsened the balance accounts of the elderly households with both housing and other real estates, it is implied that the purchase of real estates with excessive bank loans could make them dangerous.

This paper aims to analyze the characteristics of hotel REITs' performance and operation, and to examine their use for activating the hotel industries in Korea. The results of this study are as follows. First, hotel REITs underperformed average REITs and investment proportion of hotel REITs compared to total REITs has been curtailed after 1998. This is because performance of hotel REITs is sensitive to business fluctuations. Second, hotel REITs have mainly invested chain hotels, and shared their role with professional hotel management companies. Third, hotel REITs are to be useful for activating the hotel industries in Korea. In this context, major implications are presented to use healthcare REITs effectively.

지난 40년간 한국에서는 농업생산 특히 쌀 생산의 가속화를 위한 노력으로서 관계사업에 큰 비중을 두어 왔다. 따라서 관계건설과 농지개량에대한 투자는 괄목할 만큼 신장되어 1960년 대 이래 총투자액은 미화 61억달러에 달하고 있다. 그 결과 관계에 대한 잠자력과 관계면적은 크게 확장되어 지난 40여년간 순관계면적은 1945년의 188.200ha로부터 1988년의 195.750ha로 증가 되었으며 이 숫자는 한구구 총 수면적의 73%에 이르는 면적이다. 한국에는 농업수자원의 개발과 관리를 계획, 실시하는 임무가 부여된 국가기관이 있다. 그러나 이에 관련되는 국가수준의 기관이 하나이상이므로 관련되는 기관간의 통합이 문제로 제기되고 있다. 이러한 문제는 얼마간 인식디되고 있지만 아직도 심각하게 남아 있다. 농지개량조합 농촌근대화촉진법에 의하여 조직되고 운영되고 있다. 각 조합에서는 관계관리에 대한 정책, 관계수 분배계획 수자원관리 등을 담당하는 농민관계단체인 흥농계가 조직되고 있다. 농가수준에서의 관계개발 및 관리에 관련되는 문제점 및 주요쟁점은 다음과 같음을 확인할 수 있었다. 1. 관계조직 및 물 사용의 저효율 2. 몽리 구역내의 부과 합리화 및 징수방법 3. 수제의 부과 합리화 및 징수방법 4. 현재의 낡은 관계조직 5. 관계시설을 효율적으로 운영, 유지관리 하기위한 훈련된 인력 6. 관련 기관간의 통합 한국의 현 경제성장 단계에 비추어 볼 때 물의 수요와 수자원의 고갈이 증대되고 있으며 새로운 수자원 개발은 점점 어려워지고 또 고가이다. 따라서 더 이상의 발전을 위해서는 토지와 수자원의 효율적이고 경제적인 이용은 물론 현재 관계조직의 개선과 집중적인 관리가 강조 되어야할 것으로 생각된다.

자원고갈로 인해 국가적 사명을 투자되고 있는 대체에너지 개발은 현재 답보상태에 머물고 있다는 평가가 지배적이다. 고유가 시대 도래로 인해 에너지비용이 증가하고 대외적으론 기후변화협약시대가 다가오면서 국내 산업체에겐 대체에너지 개발보급은 절대절명의 과제로 떠오르고 있다. 이는 심야전력 보급에서 정책적인 문제를 드러내면서 더욱 절실히 요구되는 실정이다. 그럼에도 현재 대체에너지 개발보급은 그동안 기술개발에 치중해 보급에는 문제점을 들어내고 있는 상태다. 88년부터 2000년말까지 태양열, 연료전지 등 11개 분야에 1742억원이 투자되었다. 부문별 보급실적을 보면 태양열의 경우 태양열 온수기 18만 5천대와 급탄설비 3천대, 태양관의 경우 마라도등 12000개소에 약 4000kw, 풍력은 제주지역 등 17기를 보급, 약8000KW, 폐기물은 서울 경기 부산 등에 473기를 설치 가동중에 있다. 이 대체에너지의 현재 비중을 보면 폐기물이 $93.4{\%}$, 바이오 $3.3{\%}$, 태양열 $2.1{\%}$, 소수력 $0.8{\%}$등으로 나타났다. 현재 정부는 2003년까지 대체에너지 $2{\%}$보급을 목표로 하고 있다. 그러나 대체에너지는 산발적인 기술개발 과제추진으로 인해 특정분야의 전략적 개발 보급에 문제를 드러내는 등 회의적이다. 이와 함께 정부에만 매달려 있는 업계의 자립부족이 큰 문제점으로 지적되고 있다. 이러한 문제를 해결하기 위해선 현재의 개발과 보급의 괴리를 해결할 보완책을 제시하고, 정부는 기술성 경제성 시장성을 동시에 고려하는 체계적인 계획을 세워야 한다.

Using the inter-industry tables over the period 2010-2013 published by the Bank of Korea, this paper attempts to uncover the national economic role of the marine environmental industries through the estimation of their market size and value-added, and to analyze their economic effects through inter-industry analysis. The results show that the market size of the marine environmental industries has increased from 1.34 trillion won in 2010 to 1.97 trillion won in 2013 and their share in total national output went up from 0.04 % in 2010 to 0.05 % in 2013. Moreover, the value-added of the marine environmental industries, 618.5 billion won in 2010, amounted to 841.5 billion won in 2013 and their proportion in total national value-added has grown from 0.05 % in 2010 to 0.06 % in 2013. Three findings emerge to be used demand-driven model from the inter-industry analysis. First, the production-inducing effect of 1.0 won production or investment in the marine environmental industries has decreased from 1.8845 won in 2010 to 1.8115 won in 2013. Second, the value-added creation effect of that has declined from 0.7680 won in 2010 to 0.7063 in 2013. Third, the employment-inducing effect of 1.0 billion won production or investment in the marine environmental industries has went down from 10.17 people in 2010 to 9.18 people in 2013. In short, the market size and value-added of the marine environmental industries show an increasing trend, but their economic effects reveal a diminishing trend.

High-cell-density cultivation of Ralstonia eutopha KHB 8862 by fed-batch fermentation in a 200 l pilot plant was carried out for the mass production of poly(3-hydroxybutyrate) (PHB). After 80 h of cultivation, the dry cell weight (DCW), PHB concentration, and PHB yield from fructose syrup reached 168 g/l, 74%DCW, and 0.27 (w/w), respectively, resulting in a productivity of 1.6 g of PHB/L/h. Based on these results, the PHB production cost from bacterial fermentation was analyzed and economic evaluation was performed. In the case of new investment being implemented or not, the production cost of PHB was US$ 3.15/kg and US$ 2.41/kg, respectively. PHB productivity and PHB yield on a carbon substrate were both important factors to be optimized. The increase of PHB yield on a carbon sources significantly decreased the PHB production cost but the increase in productivity had a relatively slight effect on the decrease in PHB production cost because the cost of carbon sources (37%) for PHB was larger in proportion to total cost than the depreciation cost (17%). These results suggest that the increased PHB yield from carbon sources and the development of new cheaper substrates would be more effective in decreasing PHB production cost than the increase in productivity. It was demonstrated that PHB is not in competition with consumable plastics such as PET in present market. Therefore, it is essential to lower production cost to be used as a bulk product and desirable to develop new application fields for PHB such as biomedical and cosmeceuticals.

The study analyzed the financial determinants of corporate R&D intensity that require more attention from academics and practitioners in the Korean capital market. Domestic small and medium enterprises (SMEs) may face with developing substitutes by making more R&D investments in scale and scope, given the unprecedented economic conditions such as the limitation of importing core components and materials from other nation(s). KOSDAQ-listed SMEs were selected as sample data, whose R&D expenditures may be less than those of large firms during the post-global financial turmoil period (2010~2018). Static panel data model was applied, along with Tobit and stepwise regression models, for examining the validity of results. Logit, probit, and complementary log-log regressions were also employed for a relative analysis. R&D expenditures in the prior year, the interaction effect between the previous R&D intensity and high-tech sector, firm size, and growth rate were significant to determine R&D intensity. Moreover, a majority of explanatory variables were found to change between the years 2011 and 2018, while time-lagged effects between the R&D intensity and growth rate exist. Results of the study are expected to be used for future research to detect optimal levels of R&D expenditures for the value maximization of SMEs.

R&D (Research and Development) investment by companies and the government continues to increase, and the total R&D expenditure of public and private sectors in 2021 reached KRW 102 trillion, and the ratio of R&D investment to GDP was 4.96%. It ranks second in the world after Israel. This study analyzes the current status of the domestic R&D service industry and the research and development (R&D) innovation ecosystem based on the business activity survey data of the National Statistical Office in terms of improving R&D productivity of domestic R&D investment that has exceeded 100 trillion won, and analyzes the global R&D service industry and analyzes the global research service industry and R&D service Industry support government policy As a result of the analysis, in the domestic R&D ecosystem, the R&D outsourcing demand of service companies is rapidly increasing, compared to the stagnant R&D outsourcing demand of traditional manufacturing companies. In order to respond to these changing demands for technological innovation, this study suggests balanced support for R&D outsourcing for manufacturing and service companies, expansion of domestic R&D outsourcing, establishment of R&D outsourcing strategies specialized for the service industry, establishment of an open R&D ecosystem, and innovation in connection with materials/parts/equipment strategies.
