Evolution of Science and Technology Innovation Network Among Cities from the Perspective of Patent Cooperation—Take Xi'an as an Example
From the perspective of patent cooperation,this paper studies Xi'an participation in the national innovation network.On the basis of combing relevant literature,through Innojoy patent database,this paper selects and downloads the patent data of Xi'an from 2011 to 2021.Based on the patent cooperation data of Xi'an in the past decade,this paper builds the national scientific and technological innovation network of 2011-2021,and on this basis,uses the growth quantity analysis and function multicenter iterative analysis of the past decade,analyzes the evolution trend of Xi'an network to explore its position in participating in the national science and technology innovation network.Research has found that:(1)Xi'an has played a relatively important role in the national science and technology innovation network,with its main innovation connection areas not only concentrated in other provincial capital cities,but also a considerable portion concentrated in cities within the province.(2)There are significant differences in the strength and breadth of technological innovation connections between Xi'an City and 15 other cities in the country,as well as different emphasis on the quality and direction of cooperation patents between cities.(3)In the national science and technology innovation network,each city exhibits a multicenter high and low distribution characteristics.At present,Xi'an is in a relatively small core position,and is already classified as"marginalized"among the top 10 cities.There is a significant gap in the strength of science and technology innovation connections with the top few cities,and there are still many links that need to be improved.(4)Trend of patent cooperation between Xi'an and cities within the province has become more obvious.However,there are still many shortcomings that need to be improved in comparison with domestic first tier cities and new first tier cities,and the trend characteristics of development and evolution are not clear enough.The innovation status of patents in Xi'an has constantly improved,and the growth rate is also constantly increasing.However,looking to the country,patent data in Xi'an still has the characteristics of extensive quantity but not in-depth content,diversified coverage but not detailed research fields.Compared with other cities in the country,there is a significant gap in the strength of its technological innovation connections.
