Abstract The essence of patent system is to determine the ownership of intellectual property rights. Basing on the first and second batch of patent insurance policies, which were be seen as a quasi natural test, with the help of the data of listed companies from 2008-2017, the impact of patent enforcement insurance on the innovative behavior is tested by the DID method. The research found that: Patent enforcement insurance has strengthened the protection of intellectual property rights, which can significantly promote the innovation enthusiasm of the listed companies and increase the innovation investment; Patent enforcement insurance can significantly increase the patent application and patent authorization of the listed companies. Further research has found that the statedowned property, the faster the process of marketization and the complete the legal system, the more significant the incentive effect of the patent enforcement insurance can be promoted. After the sensitivity test and instrumental variable method are applied to control the endogeneity, the above conclusions are still valid. The research shows that strengthening the construction of patent protection system is of great significance for promoting the innovation of listed companies.
