目前我国家庭金融的发展并不充分，同时居民健康对股市的影响也在不断增强，尤其是在当前新冠疫情的冲击下，研究如何从居民健康的角度提高家庭参与股市具有重要意义。在这种情况下，基于2017 年中国家庭金融调查（CHFS）数据，研究居民健康对我国家庭参与股市的影响，在此基础上使用中介效应检验模型考察居民健康对我国家庭参与股市的影响机制，研究发现：居民健康在整体水平上能够显著促进家庭参与股市和投资股票比重，但男性和未婚居民的健康状况对家庭参与股市的促进效果更强，女性和已婚居民的健康状况则更益与提高家庭投资股票比重。此外，居民健康会通过金融素养和社会活动间接影响家庭参与股市和投资股票比重，但金融素养对参与股市和投资比重的中介效应均强于社会活动。以上结论为从居民健康的角度提高参与股市，促进家庭金融充分发展提供了一定的经验依据。

At present, the development of household finance in China is not sufficient, and the impact of residents health on the stock market is also increasing. Especially under the impact of COVID-19, it is of great significance to study how to improve the participation of households in the stock market from the perspective of residents'health. Based on the data of China Family Finance Survey (CHFS) in 2017, this paper studies the influence of residents health on Chinese families'participation in the stock market, and then examines the influence mechanism of residents' health on Chinese families'participation in the stock market by using the mediating effect test model.The results show that residents-health can significantly promote families-participation in the stock market and the proportion of investment stocks on the whole level; the health status of male and unmarried residents has a stronger effect on families'participation in the stock market, while the health status of female and married residents is more conducive to increasing the proportion of family investment stocks. In addition, residents'health will indirectly affect the proportion of families participating in the stock market and investing in stocks through financial literacy and social activities, but the mediating effect of financial is stronger than that of social activities. The above conclusions provide a certain empirical basis for improving the participation in the stock market and promoting the full development of family finance from the perspective of residents'health.
