Research Review on Equity in Basic Medical Insurance

Abstract

This study focuses on the equity of basic medical insurance. Through reviewing a large number of relevant literatures, the theoretical sources, measurement methods and empirical research on equity in basic medical insurance are summarized. The study found that scholars currently conduct research on the equity of basic medical insurance mainly from the two theories of welfare economics and social justice theory. Scholars generally use the concentration index, the level index, and the regression method to measure the equity of basic medical insurance. Many empirical studies have shown that basic medical insurance improves the level of health care and health on the one hand, but on the other hand it widens the fair gap between the insured and the non-insured. This paper concluded that the current equity of basic medical insurance still has certain limitations, and future research can progress toward related research. I hope this study can provide a reference for improving health and equity.
