Spatial Correlation of Eco-efficiency of Construction Land in Urban Agglomeration in the Middle Reaches of the Yangtze River Considering Carbon Emission
Based on the data of 28 cities in urban agglomera-tion in the middle reaches of the Yangtze River,taking carbon emissions as unexpected output,we use super slack based measure model to calculate the eco-efficiency of urban con-struction land in this urban agglomeration from 2010 to 2016,and use social network model to analyze the spatial correlation and formation mechanism of the eco-efficiency of the urban con-struction land.The results show that the overall eco-efficiency of this urban agglomeration is low,its network structure is strong in the south and weak in the north,and the spatial corre-lation needs to be strengthened.The differences of urban eco-nomic development level and population size are the main driving factors.Therefore,improving the network relation-ship of land eco-efficiency of the urban construction land in ur-ban clusters is essential for the green development of urban clusters to further improve the population agglomeration scale and economic development level of core cities,unify emission standards,strengthen industrial cooperation among cities,and achieve collaborative emission reduction.
