Spatial Structure of China’s Green Development Efficiency: A Perspective Based on Social Network Analysis

Clarifying the spatial correlation network structure of green development efficiency (GDE) is great significance for realizing coordinated and sustainable in China. By constructing evaluation index system GDE, this study used super epsilon-based measure (EBM) model that considers undesirable output to GDE China from 2000 2018, based on which characteristics influencing factors were analyzed using social analysis (SNA) a geographical detector. The results indicated that: (1) as whole remained relatively stable, there was significant spillover effect between provinces; demonstrated complex dense characteristics, closeness stability gradually increased. However, strict hierarchical still existed. (2) eastern coastal provinces exhibited effects connectivity functions, while northeastern central-western are located at edges network. (3) divided into leader subgroup, bridge subgroup net benefit with no isolated subgroup. (4) economic level, urbanization financial have decisive impact formation
