This Article analyzes the structure of Global Infra Fund(GIF) to explore related issues, and suggests possible improvements thereof. GIF was implemented for the purpose of reviving construction companies suffering from recess of the South Korean construction market, by investing in infrastructure projects funded by overseas through public private investment fund(PPIF). GIF, however, has encountered numerous difficulties including failure to secure private investors. Regarding this issue, this Article points out the following issues: ① use of borrowing funds(leverage), ② issues caused by failure to borrow funds, ③ and issues caused by failure to provide securities for the funds. Resolving the issues above is expected to revitalizing inducement of private investments, facilitation of project implementation, improvement of project cash flow, enhancement of dividend rate and risk distribution. Since GIF is a fund created for policy purposes, a special case provision needs to be introduced into the Enforcement Decree of the Financial Investment Services and Capital Markets Act, to improve GIF in a flexible way.
