The supervision of commercial insurance is an important part of financial supervision. For a long time, there are many studies on the banking and securities regulatory system in China, and the research system is more perfect. However, there is little research on the issues related to the regulation of commercial insurance. This is not consistent with the systematic importance of the insurance institutions in the financial system, and is not consistent with the increasing economic status of the insurance industry in the national economy. Therefore, the actual situation of domestic insurance supervision is studied. The experience of insurance supervision in developed countries is used for reference. The basic concept and necessity of commercial insurance regulation are explained. The basis and significance of the regulatory system of commercial insurance are analyzed. Finally, the path of perfecting China's commercial insurance supervision system is proposed.
