Spatial interaction network structure and its influence on new energy enterprise technological innovation capability: Evidence from China

Improving the new energy enterprise technological innovation capability can effectively protect the ecology of the environment and reduce the consumption of resources. Based on the gravity model and the quadratic assignment procedure analysis method, this paper builds the spatial interaction network of new energy enterprise technology innovation capability. In this paper, we analyse the structural characteristics of the spatial interaction network and explore the main factors that influence it. The results show that the spatial interaction network of new energy enterprise technological innovation capability is robust. The network relations are closely linked, and there is no strict grade in this spatial interaction network. There are both centralization and marginalization trends in this network, and the block division is obvious. In addition, if there is proper reception, transmission capability, economic distance, and geographical distance are the main factors that can impact the interaction strength of this network. According to empirical research results, the relevant policy recommendations for promoting the new energy enterprise technology innovation capability are proposed. The policy recommendations include establishing the new energy technology innovation exchange platform, formulating regional development policies for the new energy enterprise, and improving the regional investment financing mechanism of the new energy enterprise.
