Abstract: Based on the 2016 Green Development Index of 31 provinces in China jointly issued by four ministries,this paper applies the gravitational model and social network analysis method to comprehensively analyze the spatial correlation and spillover effect of China’s inter-provincial green development.The findings show that the spatial correlation of China’s inter-provincial green development has remarkable accessibility,stability and non-equilibrium.There is a close connection and significant spillover effect between provinces or plates;the eastern provinces are mainly net income segments,having more close relevance between each other;the central and western provinces are mainly net spillover plates.The center of green development is mainly concentrated in the eastern regions,which receive more spillovers and constantly attract the inflow of green development elements and resources,exerting greater impact on the green development of the related provinces.Each province has significant differences in geographical location,ecological environment endowment,technological innovation,urbanization level and environmental regulations,etc.,that has jointly promoted the formation of inter-provincial correlation and spillover effect of green development.We should establish the green development concept of spatial integration,give full play to regional correlation and spillover effects,make differential regional policies,and form green development pattern of regional equilibrium and synergy.

Key words: green development, gravitational model, social network analysis, spatial correlation, spillover effect
