Abstract: As an important part of Chinas innovation system,universities innovation level plays an important role in promoting the development of social innovation in China.The university science and technology park integrates enterprises,universities,and the government into an industry university research cooperation system,which provides the possibility for the spillover and reproduction of university innovation output.The study of university science and technology parks on university innovation output will be beneficial for understanding the mechanism of university innovation output.Using a multi-period double difference model to evaluate the impact of university science and technology parks on the output of university patent innovation,it finds firstly,national university science and technology parks can promote a 31% increase in invention patents among participating universities.Secondly,national university science and technology parks in the eastern region can better promote the growth of invention patents in universities,while national university science and technology parks in the central and western regions cannot significantly affect patent changes in universities.Thirdly,only science and engineering universities can be influenced by the National University Science Park and exhibit a growth effect in invention patents.Fourthly,after universities participate in the National University Science and Technology Park,ordinary universities have a higher increase in patent output compared to high-level universities.Fifth,further analysis reveals that the growth of university patents participating in national university science and technology parks is also conducive to the transfer of patents by universities.The above results indicate that the mechanism of the role of university science and technology parks in universities needs to be viewed and planned rationally in order to achieve a win-win situation between Universities and university science and technology parks.
