Abstract:Technology-based SMEs are an important force in China"s economic development, and it is of great significance to study the Intellectual Property financing performance of SMEs for the development of enterprises. Taking 215 enterprises listed on the Star Market as a sample, this paper empirically examines the relationship between the innovation efficiency and equity financing performance of listed companies on the Star Market, and finds that: (1) the innovation efficiency positively affects the performance of intellectual property equity financing;(2) Through the heterogeneity test, it is found that enterprises with financing constraints, low degree of equity concentration, and enterprises with property rights that are non-state-owned have a significant relationship between innovation efficiency and performance of intellectual property equity financing; (3)Government subsidies play an intermediary role in the relationship between innovation efficiency and IP equity financing performance. In addition, on the basis of empirical research, corresponding countermeasures and suggestions are put forward to improve the performance of enterprise intellectual property equity financing.
