This article suggests a methodology to decide the priority of investment project for venture business under the dynamic circumstance. By the Monte Carlo procedure on the probability distribution of cost and revenue, the model simulates the investment project to estimate profit ratio and risk. The profit ratio is calculated on the yearly basis for the relative comparison. The project risk is calculated as semi-variance under the target yield. After sufficient simulations in this fashion for several projects, the efficient projects with more profit and less risk are selected by the dominance principle. Then the regression equation of the selected projects is produced to find the relative value of the projects. The relative value is obtained through dividing the raw profit ratio by the estimated one on the equation. This value shows the degree to which the simulated project yields over the equation. The priority of investment is decided by this value. An examplary venture business of chemical development for semi-conductor is presented as a case study.

본고는 1991~2003년의 기간중 우리나라 상장 제조업의 기업별 자료를 이용하여 불확실성과 투자의 관계에 대한 부분적인 검증을 시도하였다. 실증분석 결과 외환위기 이후의 기간에서만 불확실성이 투자에 영향을 미친 것으로 나타났으며, 또한 외환위기 이후의 기간중에서도 재무건전성이 낮은 기업에서 불확실성의 영향이 강하게 추정되었다. 이러한 분석결과는 외환위기 이후 기업의 위험기피성향이 증가하였으며 기업경영이 보수화되어 왔음을 시사하고 있다. 한편 외환위기 이전에는 투자와 현금흐름 사이에 높은 상관관계가 추정된 데 비하여, 외환위기 이후에는 이러한 상관관계가 발견되지 않아 투자자금의 공급과 관련된 금융제약이 투자에 미치는 영향은 상대적으로 약화되었음을 의미하고 있다.

This paper aims to determine factors causing the stagnation of Korean firms' fixed investment after the global financial crisis, using panel data for the period of 1999-2016. Fixed investment remained sensitive to cash flow and Tobin's q although their effects decreased after the global financial crisis. A decreasing trend of cash flow and an increase in Tobin's q since the early 2000's imply that the worsening cash flow was a major factor behind the sluggish investment after the crisis. Meanwhile, debt-equity ratio remained significant for non-chaebol affiliated firms, reflecting disparity in access to external financing. Volatility of stock returns also became insignificant after the crisis, casting doubt on the argument that uncertainty was a major factor contributing to the decline of fixed investment. Analysis of financial investment confirmed the significant effect of cash flow, larger than that on financial investment than on fixed investment. In particular, debt repayment and other financial investment, except share repurchase, were sensitive to cash flow. However, the substitution of fixed investment by financial investment is a consequence, rather than a cause of declining fixed investment.

Purpose: The purpose of this paper is to empirically investigate the relationship between government subsidies and research and development (R&D) investment of animal husbandry companies in China. The moderating effects of firm size, debt ratio, and firm profitability on this relationship are also examined. Research design, data and methodology: The analysis is based on 14 animal husbandry companies listed on the Shanghai and Shenzhen stock exchanges over the period of 2012-2016. Data are obtained from the China Stock Market & Accounting Research (CSMAR) database and the RESSET database, and multiple regression analysis is utilized with the aid of Stata. Results: The empirical results show that government subsidies can promote R&D investment of animal husbandry companies in China. In addition, firm size, debt ratio, and firm profitability have positive moderating effects on the relationship between government subsidies and R&D investment. Conclusions: Based on the results, the paper concludes that government subsidies play an important role in the process of R&D of China's animal husbandry companies. This paper recommends that managers of animal husbandry companies should enhance the utilization efficiency of government subsidies and put great emphasis on R&D investment. The policymakers should implement more incentives to encourage animal husbandry companies to invest more in R&D.

In order to expand its entry into not only the domestic construction market but also overseas global markets, it is necessary to secure technological competitiveness, and as a fundamental measure, it is necessary to increase the proportion of R&D investment and establish and revitalize R&D organizations. Therefore, the purpose of this study is to analyze construction sales and construction R&D investment for global construction companies in Korea and Japan, derive implications, and provide basic data for government policy establishment and global construction company strategy establishment. As a result of analyzing R&D investments in construction companies in Korea and Japan, it can be seen that Japanese construction companies have higher R&D investment costs compared to sales compared to Korea. In particular, the proportion of R&D investment continues to increase year-on-year, strengthening global competitiveness due to technology development. In addition, Japanese construction companies have established a technology research institute to discover and conduct future R&D research such as advanced IT, disaster prevention, and environment.

The objective of this study is to review the methodology of economic analysis of fishing ports by examining the economical feasibilities of a national fishing port (Jeongja Port) in Ulsan. This study utilized market value evaluation method to measure the benefits and costs related to the development of ports. The benefit variables are income effects resulting from the developments while the cost variables are sum of construction costs and maintenance costs. The income effects are measured in two ways: (1) income from individual project resulting from the developments, (2) the income effects by utilizing investment multipliers. The results shows that the BC ratio (Benefits/Costs) of Jeongja port by using (1) income from individual project resulting from the developments was 1.07 while the BC ratio by using (2) the income effects by utilizing investment multipliers was 1.10 due to a relative short period of useful life for investment multipliers. However, the income variable utilizing investment multipliers is more sensitive to the period of duration than the income variable from individual project.
