Research on the Structure Evolution and Influence Factors of Collaborative Innovation Units Network in Chengdu-Chongqing Economic Circle
Based on the joint patent application data of Chengdu-Chongqing Economic Circle from 2010 to 2020,this paper examines the structural evolution characteristics of the collaborative innovation units network,and empirically tests its influencing factors by using QAP regression analysis.The results show that the collaborative innovation units network of Chengdu-Chongqing Economic Circle has the characteristics of small world and shows good toughness and self-stability.The internal distribution of the network is uneven,universities occupy the central position of the network,and the proportion of enterprise units in the network nodes is the highest.However,compared with the breadth of collaborative innovation,enterprises emphasize the depth of collaborative innovation.Geographical proximity has a positive impact on the establishment and strength of collaborative innovation relations.Cross regional collaborative innovation between Sichuan and Chongqing still needs to be deepened.Compared with the cooperation mode between universities and enterprises,the probability and intensity of collaborative innovation between universities and colleges,and between universities and scientific research institutions are higher,and the probability of collaborative innovation between enterprises and enterprises,and between enterprises and scientific research institutions is lower.It is necessary to improve the key role played by enterprises in the innovation system,enhance the collaborative innovation capacity of Chengdu-Chongqing Economic Circle,and promote the deep integration of the innovation chain,industrial chain,capital chain and talent chain.
