Does Participating in New Rural Cooperative Medical Insurance Change Catastrophic Health Expenditure? Evidence from the China Household Income Project.

A primary goal of the New Rural Cooperative Medical Insurance (NRCMI) is to provide financial protection against health care costs and alleviate the financial burdens of rural residents in China. This article examines whether NRCMI participation impacted the incidence of catastrophic health expenditure (CHE) among middle-aged and older adults (45 years old and above). The analysis utilized data from the 2007 China Household Income Project survey in rural areas and an instrumental variable estimation method in Anhui and Sichuan provinces, which exhibited heterogeneity in the NRCMI implementation schedule. The results show that NRCMI participation was not associated with changes in the CHE incidence among families. The finding is consistent with the prior literature using quasi-experimental study designs. This study provides empirical evidence for policymakers, highlighting that the impact of NRCMI participation on financial protections is limited despite its extensive population coverage. The limited effects are probably due to the low reimbursement rate and increased utilization of expensive health care services.
