This paper uses data from the China Health and Nutrition Survey (CHNS) to study the impact of market integration on residents' health. The empirical results based on the probit model show that market integration has a significant dampening effect on resident incidence. For every one-unit increase in the degree of market integration, the probability of residents becoming sick decreases by approximately 1.45%. Moreover, after a series of robustness tests, the conclusion is still valid. This study further analyses the potential mechanism and finds that the promotion of market integration can improve the medical conditions available to residents, optimize the nutritional indices of residents, and reduce labor load of residents, thus improving their health. The results of the heterogeneity test show that there are certain differences in the impact of market integration on the health level of residents of different genders, ages and income classes. At the same time, this study also verifies that there is a synergistic effect between internet penetration and market integration.
本文使用中国健康与营养调查（CHNS）的数据来研究市场一体化对居民健康的影响。基于概率单位模型的实证结果表明，市场一体化对居民发病率有显著的抑制作用。市场一体化程度每提高一个单位，居民生病的概率约降低1.45%。此外，经过一系列稳健性检验后，该结论仍然成立。本研究进一步分析了潜在机制，发现市场一体化的推进可以改善居民可获得的医疗条件，优化居民的营养指标，并减轻居民的劳动负担，从而改善他们的健康状况。异质性检验结果表明，市场一体化对不同性别、年龄和收入阶层居民健康水平的影响存在一定差异。同时，本研究还验证了互联网普及率与市场一体化之间存在协同效应。
