The vigorous development of the sharing economy has helped China's market economy to make steady progress. The sharing of social idle resources has greatly improved the utilization rate of resources. However, the imperfection of the corresponding legal system makes the legal status of the sharing economy unclear, and the lack of regulatory measures leads to its disorderly development and the waste of a large number of resources, which also brings considerable legal risks to the supply and demand sides of the sharing economy. As a new economic model, the sharing economy still lacks corresponding laws and regulations in terms of laws, so it is prone to legal risks. Therefore, it is necessary to analyze the legal risks existing in the sharing economy and put forward reasonable prevention suggestions in order to promote the development and growth of the sharing economy model.
