Abstract: This paper constructs a green development evaluation index system based on DPSIR model, and explores its spatial network structure on the basis of measuring regional green development level. The results are as follows. (1) Green development is not balanced among regions. The level of green development in each region can be divided into four categories: mature type, rapid development type, gradual promotion type and early growth type. Economically developed regions are more likely to generate development advantages through “response + drive”, while resource-dependent and traditional industry-intensive regions lag behind in green development due to lack of innovation. (2) In the space network, inter-regional connectivity is strong and there is no strict hierarchical structure, which is conducive to promoting inter-regional cooperation and complementarity. However, the stability of the network is weak, and a high-quality regional cooperation pattern has not yet been formed. (3) Location factors, rather than capacity factors, are the key to whether a region can occupy an important position in the space network. Compared with regions at high levels of green development, regions at low levels of green development are more likely to produce spillover effects. The research results provide ideas for further promoting high-quality green development in China. On the one hand, all regions should pay attention to the coordinated development of DPSIR elements, open up the transformation channel of “policy-response-driving force”, excavate the driving path from productivity to “pressure reduction-state improvement-green welfare”, and explore the high-quality development path according to local conditions. On the other hand, it is necessary to break the barriers between regions, give play to the role of specific regional ties, stimulate the leading role of green areas, increase support for weak green areas, build a spatial pattern of green, low-carbon and high-quality development, and promote coordinated regional development.
