공공투자사업평가 시 사회적할인율의 높고 낮음에 따라 비용 편익분석의 결과가 상이하다는 점에서 적정 수치는 매우 중요한 요소이다. 그리고 사회적할인율의 개념을 무엇으로 적용하는 것이 합리적인지에 대한 많은 논란과 연구가 현재까지 진행되고 있다. 본 연구에서는 사회적할인율의 개념을 크게 세 가지 사회적 시간선호율, 사회적 투자수익률 그리고 이 둘을 가중평균 한 값으로 구분하였다. 추정방법으로는 사회적 시간선호율의 경우 소비이자율과 Pearce and Ulph식을 사용하였고, 사회적 투자수익률은 민간 총 자본 수익률을 사용하였다. 그리고 가중평균은 투자의 잠재가격을 이용한 Squire, L., Herman G. van der Tak식과 공공투자와 대치되는 민간투자와 민간 소비지출비율을 이용하여 추정하였다. 본 연구에서는 현재 시점의 사회적할인율을 추정하기 위해 연대구분을 1990년대, 2000년~2003년, 2004년~2008년으로 각각 구분한 후, 과거 한국개발연구원에서 제시된 1999년 7.5%, 2004년 6.5%, 그리고 2007년~현재 5.5%와 각각 비교하였다. 추정결과는 1990년대 6.6~10.7%, 2000년~2003년 4.0~7.0%, 2004년~2008년 2.4~3.9%로 각각 추정되었다. 현재 공공투자 사업평가에 사용되고 있는 사회적할인율 5.5%는 본 연구의 추정결과 보다 약1.6~3.1% 높은 것으로 나타났다. IMF이후 급격하게 하락한 소비이자율은 계속적으로 낮아지고 있고 앞으로도 지속될 것으로 예측하고 있다. 따라서 공공투자 사업의 목적인 현 세대부터 장래세대까지 모두를 고려한 사회적 자원의 재분배를 실현시키기 위해 선 현재의 사회적할인율은 점차 하향조정할 필요가 있다.

The objectives of this study are to investigate the relationship between the growth of the horticultural sector and horticultural research and extension and to examine the socioeconomic returns to investment on research and extension in Korean horticulture. Data for horticultural production values, producer price indices and research and extension budgets for horticultural sector from 1965 to 1998 are collected from various sources. Multi-variate time series analysis technique with vector auto-regression model and Akino-Hayami Formula were employed for the analysis. This study finds (1) horticultural production responds about seven years later to the horticultural research investment shock. the magnitude of the impacts increases to a peak in seventeen years from the initial expenditures and then declines slowly thereafter until twenty years. and this peak gives a tip that horticultural research impact lasts much longer than grain's or agriculture's: (2) the social surplus from research investment benefits more to the consumer rather than to the horticultural producer: (3) B/C ratios in horticultural research are quite high with the range of 9 to 55 from 1965 to 1998. but these have been decreased since the early 1990s: (4) the socioeconomic returns to horticultural research is quite high with 56 percents of internal rate of return. It remains to be analyzed returns to investment on extension in horticulture because of no statistic significance in this study.

PURPOSES: This study is to suggest the Contribution of Road Capital in Industry and Optimal Level of Road Investment in South Korea METHODS: Based on the literature review, This research is empirically estimated using disaggregate and disaggregated data composed of 10-sectors covering the entire korea economy for the period 1970~2000. The relevant policy questions addressed in this report are : cost reduction and Scale elasticities of road, effect of road capital stock on demand for labor, capital and materials, marginal effect of road, industry TFP growth decomposition, Net Social Rates of Returns, optimal of road capital. RESULTS : The marginal benefits of the road capital at the industry level were calculated using the estimated cost elasticities. Demand for the road capital services varies across industries as do the marginal effects. The marginal benefits are positive for the principal industries. This suggests that for these industries the existing stock of road capital may be under supplied. CONCLUSIONS: This results emerges is that the ratio of the optimum to actual road capital, measured by road, was high at beginning of the period 1970s and declined 1990s. There appears to be evidence of under-investment in road capital. That is continuous and premeditated investment for road which lead to saving time and finance.

This paper selects 100 IT companies listed on the Shenzhen Stock Exchange from 2016 to 2020, and the public announcement in Hwajung collects ESG integrated ratings and grades for each sector and empirically verifies the relationship between ESG ratings and stock returns. Huazheng ESG level data and QIANZHAN database Using corporate financial data, a total of 500 samples were selected through correlation analysis and linear regression analysis with SPSS23 to analyze the effect of ESG on Return. As a result of the analysis, first, the impact on stock returns was found to be a significant positive (+) value for ESG integrated ratings and ratings by E (environment), S (social), and G (governance) sectors, confirming that ESG ratings have a positive mold of corporate stock returns. Currently, the world's major economies have proposed sustainable development strategies and "carbon neutral" goals. Development strategies are very consistent with ESG concepts, and companies that agree and execute ESG concepts may have higher ratings than other companies in the same industry, resulting in certain evaluation premiums. In addition, capital market performance in recent years shows that companies with ESG concepts or "carbon neutrality" concepts are generally considered to have higher growth potential and stronger anti-risk capabilities in the market. For listed companies, they should focus on ESG investment, improve ESG performance, and actively disclose related information to investors. Improving ESG performance should deliver positive information to society, enhance corporate image, increase market confidence in the future development of listed companies, and positively improve corporate value to actively increase financial, financial, trading, and other aspects of negotiation.

This study is aimed to analyze investment effects of fisheries R&D projects of the National Fisheries Research and Development Institute(NFRDI). In the analysis, Granger causal relations between R&D investment and fisheries production are tested. In addition, time-lag effects of fisheries R&D investment are estimated with an impulse response analysis and investment effects of R&D projects are estimated by changes of social surplus. Results indicate that there exists an Granger-causality between R&D investment and fisheries production and fisheries production responds to the fisheries R&D shock about three years after the initial shock. The magnitudes of the impacts increase until a peak is reached 5~7 years and the impacts decline to zero after 25 years. As investment effects, it is shown that the internal rate of returns of fisheries R&D investment is 55.2%.

ESG 투자가 금융시장의 대세이자 상식으로 부상하고 있다. ESG 투자는 기업의 재무실적 이외에 환경, 사회, 거버넌스 등 비재무적 요소를 투자의사결정에 반영하여 장기적 관점에서 사회의 지속가능성과 투자수익을 동시에 추구하는 투자방식이다. 본 연구는 일반적으로 알고 있던 ESG 투자의 특징이 코로나19를 계기로 어떻게 변화하고 있는지를 환경, 사회, 거버넌스 관점에서 살펴보았다. 이후 코로나19가 유가증권시장에 부정적 요인으로 작용하였는지 여부를 VAR 모델을 활용하여 규명하였다. 동시에 미국과 한국의 ESG 인덱스와 벤치마크를 수익성과 변동성 관점에서 분석하여 ESG 투자가 팬데믹 국면에서도 유효한 전략임을 확인하였다. 본 연구 결과는 팬데믹 이후에도 ESG 투자의 중요성이 변함없을 것이라는 점을 시사한다. 동시에 경영자들이 수동적 ESG 경영을 지양하고 지식경영을 토대로 한 전략적 ESG 경영에 나서야함을 시사한다.

임팩트 투자는 사회적 가치와 재무적 이익을 동시에 추구하는 소셜벤처에 대한 투자로, 재무적 수익을 창출하는 동시에 다양한 사회문제를 혁신적으로 해결하는 데 중점을 둔다. 국내 임팩트 투자 생태계는 정부 및 공공기관의 주도 하에 성장하였으며, 2021년 운용자산 기준 총 7,000억원으로 3년만에 3.5배 증가하였다. 이러한 양적 성장과 함께 질적 성장을 견인하기 위하여 벤처투자와 구분되는 임팩트 투자에 대한 연구가 필요한 시점이다. 이에 본 연구는 임팩트 투자만의 차별화되는 영향요인을 실증 분석하는 것을 목적으로 하였다. 먼저 선행연구 고찰을 통해 투자 결정에 영향을 미치는 요인을 확인하고 임팩트 투자사 대표 및 심사역 11명을 대상으로 델파이 조사를 수행하여 주요 요인을 도출하였다. 이후 임팩트 투자 심사역 10명을 대상으로 AHP 조사를 실시하여 중요도 우선순위를 확인하였다. 상위 요인의 중요도는 시장>창업가(팀)>제품·서비스>재무의 순서로 높게 나타났으며, 세부요인의 중요도는 '시장의 경쟁강도 및 진입장벽>신시장 창출 가능성>시장성장 및 확장 가능성>팀의 전문성 및 역량>제품·서비스의 차별성 및 경쟁력'의 순서로 나타났다. 연구 결과, 선행연구에서 밝힌 벤처투자 결정요인과 다르게 임팩트 투자는 시장 관련 요인을 중요하게 평가하고 특히 투자 결정 시점에서 소셜벤처의 사회적 가치 보다 비즈니스 모델의 지속가능성과 수익을 중요하게 고려한다는 점을 확인하였다.

Due to the paradigm shift in fashion industry, its contribution to social activities and social enterprises' practice of ethical fashion has been on the rise lately. The surveillance and regulations of international community have increased in light of the betterment of working conditions and protection of the rights, and corporate social responsibility has been emphasized through consumers' interest in ethical consumption. In this regard, the fashion social enterprises' responsible and ethical management can both boost the trust in business and value-added. The study aims to propose feasible methods by exploring ways to induce support from central and local governments, which will lead to the activation of future fashion social enterprises and paradigms shift of consumers's perception and value. The sustainability of social enterprises requires management line or policies that consider social, environmental, economic, and political aspects of virtuous cycle, differentiated internally or externally. Fashion social enterprises also need ethic management and social responsibility management that are distinctive from general fashion enterprises. Thus, they will not be sustainable or differentiated unless entrepreneurial faith and role is not clear. Education and continuous promotion including upcycling are critical to build consumer base as they can make consumers spend ethically and recognize social enterprises. In addition, social education and public relations need to take place in order to internalize consumer pattern. The goal of sustainable corporate social activity is to change the awareness and become social investment that returns some profits to the society as members in line with reviewing corporate image. This can lead to establishing the foundation of securing a big comsumer market and winning the trust of the consumer's through corporate social responsibility and investment.

Open access is a paradigm whereby the electronic versions of scholarly publications are made freely accessible without any restrictions. It is actively promoted globally and is also promoted domestically in accordance with this global trend. However, there is a growing need to evaluate existing activities and to seek policies for the steady spread of open access. This study examines the necessity of switching to a national repository from existing institutional repositories through policy direction analysis of open repositories. We examined domestic open access policies by analysing various overseas cases and the situation in South Korea. Finally, we determined the validity of investment in a national repository by analysing its social and economic impacts using the modified Solow-Swan model. The main parameters for applying the modified Solow-Swan model were estimated, and the domestic research and development expenditure was predicted via a regression method. Then, we applied a range of rate of returns to research and development (10% to 50%) to various scenarios and examined the effects of increasing accessibility and efficiency by 1% to 10%. We found that the implementation of a national open access repository in South Korea would have a substantial impact (to the tune of 147 billion won), without considering the potential costs of such a repository. Based on the estimates of the social and economic impact of a national repository, the implementation of a national open access repository in South Korea is economically viable. Besides having beneficial social and economic impacts, a national repository is expected to enhance awareness of open access among Korean researchers and institutions.
