长江经济带城市创新空间网络结构的时空特征及影响因素OA

This paper took 110 prefecture level cities in the Yangtze River Economic Belt as research objects,and studied the net-work structure and influencing factors of urban innovation space in the Yangtze River Economic Belt through gravity models,social net-work analysis,and other methods.The results showed that:① The density,strength,and degree of agglomeration of urban innovation spatial network connections in the Yangtze River Economic Belt continued to increase.② The spatial network structure of core innova-tive cities in the upper and middle reaches of the Yangtze River Economic Belt,such as Chengdu,Chongqing,Wuhan,and Changsha,tended to develop more closely,that is,to establish innovative connections with more cities.Cities such as Shanghai,Nanjing,Hangzhou,and Suzhou in the lower reaches of the Yangtze River Economic Belt tended to"develop towards strength" after establishing connections with other cities,that was,continuously enhancing the strength of innovation connections with other cities.③The internal correlation be-tween each sector was strong,and the spillover between sectors was weak.Sector three was a net overflow sector that had spillover effects on other sectors.However,the balance of reception and overflow in sectors two and four with broker status was relatively weak,mainly due to internal correlations.④The level of economic development,innovative operating environment,and government institutional orien-tation all had a significant impact on the innovation space network of the Yangtze River Economic Belt,and were important factors driv-ing the construction of an innovation highland.
