The greed of investors has been cited as one of the principal causes of the global financial crisis, and the importance of ethical investment has been increasing, and social interest and demand for socially responsible investment (SRI) are also increasing. Socially responsible investment or sustainable investment aims to create sustainable profits of companies through long-term investment, and decides the investment intention in consideration of the corporate environment, society, and governance (ESG) factors as well as traditional financial analysis in the process of valuation and construction of investment universe. In light of this situation, this study analyzes the cases of SRI of domestic and foreign pension funds. After careful investigation of the cases of major SRI, we found that they are trying to maintain responsible investment as a sustainable investment, and they are gradually expanding the scale. Besides, the brief analysis of nominal return and risk-adjusted return of the domestic responsible investment funds indicates negative returns overall both in nominal return and risk-adjusted return. The results mainly rely on the recent sluggishness of the domestic stock market. However, if we extend the time horizon for about three years, some SRI funds’performance becomes positive. Finally, based on the case and empirical analyses, this study proposes the following directions for SRI; 1) Creating an investment environment that focuses on the intrinsic value of the company through system maintenance and system establishment for gradual expansion and implementation of SRI; 3) Development of a theme index and creation of an ESG specialized fund; 4) Need to strengthen qualitative evaluation in the ESG performance evaluation and overall performance evaluation of the pension funds; 5) In order to expand and revitalize the overall SRI, it is necessary to support academic and industrial research. It is expected that these suggestions can shed light on setting the direction of policy related to SRIs in the future.
