Does Health Insurance Lead to Improvement of Health Status Among Chinese Rural Adults? Evidence From the China Family Panel Studies

The purpose of this study is to examine the causal relationship between the New Rural Cooperative Medical Scheme (NRCMS) and health status among Chinese rural adults. The data were drawn from China Family Panel Studies performed in 2016, involving 2,093 rural adults. Furthermore, this study employed k-nearest neighbor matching out of propensity score matching (PSM) to investigate the impact of NRCMS on health status among rural adults. Moreover, radius matching, kernel matching, and nearest-neighbor matching within caliper out of PSM were adopted to conduct sensitivity analyses. This study demonstrates that NRCMS enrollment has had a significant and positive effect on the self-assessed and mental health of rural adults, and the health effect shows significant age and income disparities. Moreover, the positive health effect may result from 2 channels, including the increase of health services utilization and the fact that adults with NRCMS are more likely to seek health care in lower-level medical institutions.
