There are myriad researches on risk-sharing, benefit distribution, asset securitization, and capital structure of PPP projects these days. In this paper, we provide analysis and discussion for the research methods of selected literature which applied the most used method for measuring the optimal capital structure of public-private-partnership projects. By analyzing these studies, we can identify the potential problems of present research methods, and we can also provide research suggestions for future researchers to promote and enhance their research methods of optimal capital structure of public-private-partnership projects and make the methods more practicable and reality-adaptive.
