Abstract:Commercial insurance, as an effective supplement to social insurance, plays an important role in improving the multi-level medical security system, safeguarding and enhancing people’s livelihoods. Based on the data from China General Social Survey (2021), this paper constructs a binary Logit model through multi-collinearity testing to analyze the effect of environmental concerns on urban and rural Chinese residents’ participation in commercial insurance. The results show that environmental concerns have a remarkable effect on their participation. Furthermore, this paper examines the differential impact of environmental concerns on the participation of residents of different household registration types and health statuses in commercial medical insurance, and conducts robustness tests by replacing the Probit model. Mechanism analysis confirms that environmental governance perception plays a mediating role in the impact of environmental concerns on the participation of urban and rural residents in commercial medical insurance in China, and there is a moderating effect of environmental severity between the two. Based on empirical results, this study proposes to attach importance to public environmental education, encourage the public to protect the environment, enhance people’s awareness of risk prevention, and optimize and innovate the management of commercial medical insurance.
