Abstract:In order to further and deeply reveal the spillover path and formation mechanism of the spatial correlation of the Beijing-Tianjin-Hebei incubation industry, this paper takes 13 cities in the Beijing-Tianjin-Hebei region as samples, and uses the modified gravity model to construct the spatial correlation network of the incubation industry. The characteristics of network structure and spatial clustering are analyzed from the perspectives of overall network, individual network, and block division, and the influencing factors of the formation of spatial associations are investigated with the help of QAP regression method. The results show that the spatial linkage potential of core cities and secondary cities in the Beijing-Tianjin-Hebei region increases year by year, and decreases in gradient, there is an obvious imbalance in the status and function of the network structure, and the network structure forms net income, net spillover, and different functional sections of brokers; factors such as geographical proximity, economic development, talent investment, and technological level have affected the formation of spatial correlations. Therefore, local government of the Beijing-Tianjin-Hebei region should deeply grasp the unbalanced development pattern of that the core functional area incubation industry in the Beijing-Tianjin-Hebei region is significantly stronger than in the marginal areas of Hebei, implement differentiated development mode of incubation industry according to local conditions based on the functional characteristics of each plate of the spatial correlation network.
