This paper test the relationship among determinants of environmental investments, level of environmental investments, eco-efficiency (carbon productivity). The results show that profitability, leverage and R&D costs have a negative impact on environmental investments, and controlling ownership have a positive impact on environmental investments as well as environmental protection costs. The analysis also show that firms increasing environmental investments are able to gain superior environmental performance ($CO_2$ emission), but are negatively relationship with financial performance. Finally, the findings prove that differences exist in the relationship between determinants and effect of environmental investments when grouped by industry characteristics.

The sensitivity of investment with respect to cash flow is positive in imperfect financial markets. Using a switching regression model, cash flow sensitivity of investments in chaebol firms and large firms appears to be higher. Also, investments are found to be more responsive to cash flow during monetary contraction periods. These findings imply that monetary policy works through a credit channel. Furthermore, it appears that monetary policy exerts distributional effects as well as aggregate effects on that firms are unevenly affected by monetary changes.

The purpose of this paper is to find the desirable R&D policies in defense area by analyzing causality between GDP and R&D investments in government, private, defense sectors. We have five variables which are composed of GDP, total R&D investment, R&D investments in government, private and defense sectors to figure out the causality between R&D investment in defense sector and other components. In the course of analysis on causality, we took the unit root test of variables to prevent spurious regression. Also we need to take cointegration test about non-stationary variables before the causality test. According to these test results, we took the causality test using ECM(Error Correction Model) for the models which have cointegrating relations. And we took ordinary Granger causality test for model which doesn't have a long-run stationary relationship. As a result of the causality test, it was shown that there exists the long-nu causality to GDP and R&D investments in government and private sectors from other variables. However, there doesn't exist the causality to defense R&D investment from other variables. We found that there doesn't exist the causality between R&D investments in defense and private sectors, and that they are independent.

Energy is an essential element in economic activity and people's lives, an important resource used by various industries, and the financialization of commodity markets has led to the growing importance of crude oil turning into the same asset as other assets. Accordingly, studies analyzing the correlation between energy prices and investor sentiment explain that investor sentiment affects oil prices through economic factors and speculation. In this study, we wanted to analyze whether the impact of the most representative changes in oil prices affects investor decision making, affecting investor sentiment, and applying wavelet consistency analysis to determine how energy prices relate to investor sentiment. Studies show that policies should be focused on policy and market changes because energy prices differ by time scale and investment sentiment should be more influential in the long term than in the short term.

The purpose of this study is to examine the valuation models and valuation factors for the valuation of real estates. In Korea, the weak market conditions prevented investors from the sound investing the real estates. To develop the real estate investment market, we need the information of sale prices, volume, vacancy rates, and regulatory policies to the various types, and areas of the real estates. In addition, we have to develop the indirect investing methods such as REITs.

최근 전세계적으로 신재생에너지에 대한 관심과 투자가 증폭되고 있으며, 우리나라에서도 그 간의 지속적인 연구개발 지원에 힘입어 국산기술 확보 및 산업화가 점차적으로 이루어지고 있는 것으로 분석되고 있다. 더욱이 신정부에서는 국정지표인 녹생성장의 실현방안으로 신재생에너지에 대한 지원을 대폭 확대하고 있어 관련 기술개발 투자도 지속적으로 확대될 것으로 보인다. 본 고에서는 이러한 국내 신재생에너지 기술개발 관련 정책 및 기술개발 동향에 대하여 알아보고, 특히 급속한 성장세 속에 2008년 전세계 태양전지생산량이 7.9GW1) 에 달한 태양광 분야는 우리나라가 강점을 갖고 있는 반도체, LCD 기술과 유사하여 국내의 축적된 기술과 인프라를 활용할 경우 조기에 세계수준의 기술력을 확보할 것으로 기대되고 있으며, 정부에서는 태양광 분야를 수출전략산업화 하기위해 집중적인 투자에 나서고 있다. 이러한 상황에서 그간의 기술개발 현황, 실적 및 향후 전망 등에 대하여 살펴보고자 한다.

The significance of SMEs (small and medium-sized enterprises) is gradually highlighted as we have entered the age of "New Normal." The South Korean government support these enterprises to boost economic growth and create more jobs. It also releases numerous policies such as national R&D projects and expanding tax incentive services particularly aiming at promoting dramatic investment in R&D and technological innovation. There is a sharp contrast regarding the efficiency of direct or indirect supports for encouraging R&D investment launched by SMEs depending on researchers. However, there has been little attempt to explore the optimal combination of two policy tools. Amid promoting affiliated governmental departments in charge of SMEs policies and constantly growing R&D investment, it is an appropriate time to discuss the medium and long-term direction for the optimal policy mix of direct and indirect supports. In this study, the author obtained 32 relevant studies published earlier in the domestic journals, explored literatures more systematically, and further conducted a meta-analysis. It is dedicated to summarizing relevant controversies and organizes them empirically beyond merely verifying whether policy support stimulates private R&D investment by SMEs. The meta-analysis showed that it would be effective to support as tax for large enterprises, while subsidiary support for SMEs. However, indirect support needs to be progressively increased as direct support primarily accounts for the entire R&D support for South Korean SMEs.

The Government provides a financial assistance to stimulate firm R&D and innovation activities. Previous papers on the impact of public subsidies on firm R&D investments mainly had a focus on an individual policy tool regardless of potential impacts of other policy instruments. This study addresses this gap by examining the effects of policy mix regarding a subsidy and a tax credit. The empirical analyses from fixed effect model using Survey on Technology of SMEs 2015-2017 revealed valuable points. First, policy mix induces more R&D investment of SMEs, which in turn, shows a complementary relationship between two instruments. Second, even if impact of tax credit controlled, subsidy is positively associated with SMEs R&D investment. These findings justify policy mix interventions to promote SME R&D activity. Moreover, grants can be applied as a more useful policy tool for SMEs that are constrained by resources and capabilities.

시멘트업계를 비롯한 건설자재업계는 2013년 건설투자가 정책효과 등에 힘입어 일시적으로 증가함에 따라 출하량이 소폭이나마 회복되는 모습을 보였다. 그러나 건설투자의 회복세가 다시 2014년에 크게 둔화될 것으로 전망됨에 따라 2014년 시멘트업계의 상황은 개선되기 쉽지 않을 것으로 보인다. 이 글에서는 2014년 건설경기에 영향을 미칠 주요 쟁점요인과 아울러 2014년 국내 건설수주 및 건설투자를 전망하고 시사점에 대해 살펴본다.

선박은 해운시장에서 가장 중요한 자산이다. 이러한 선박투자에는 대규모 자본조달이 필요하며 시황 및 경기분석을 통해 고점투자를 방지하고 조달비용을 절감하는 것이 중요하며 이러한 결정이 투자 성패를 좌우한다. 본 논문은 K평균 군집화분석을 이용하여 그리스 선주와 한국 선주의 선박투자행태를 분류하고자 한다. 분석의 결과로 선박투자의 주요 요인들을 식별하여 기업차원의 선박투자의 벤티마크 투자전략을 수립하는데 기여하고자 하며 정책적 차원에서 선박투자에 필요한 전략에 대한 시사점을 도출하고자 한다.
