Abstract：Based on the data of Chinese A-share listed companies, this study uses the multi-time point difference in difference method to test the effect of national intellectual property advantage enterprises identification on the enterprises market value. It shows that national intellectual property advantage enterprises identification significantly improves the enterprises market value, which is mainly achieved by increasing equity financing, promoting technological innovation and reducing the institutional transaction costs. According to the sub-sample regression, the value enhancement effect of national intellectual property advantage enterprises identification is more obvious in non-state-owned enterprises, growing enterprises and areas with higher intellectual property protection level. Further analysis shows that the national intellectual property advantage enterprises identification has significant industrial demonstration effect. In addition, compared with the national intellectual property demonstration city construction, national intellectual property advantage enterprises identification has a more significant effect on the enterprises market value, and the two policies have produced the synergistic effect.
