摘　　要：基于成渝城市群16个区域2010—2018年绿色发展相关指标数据,采用超效率SBM模型测算绿色发展效率水平,进而运用社会网络分析方法分析成渝地区双城经济圈区域绿色发展效率的空间网络关联特征和空间结构.研究结果表明:成渝地区双城经济圈整体绿色发展效率水平受成渝非双圈区域影响较大,其变动趋势呈现阶段性“V”型波动,且区域间空间关联突破了地理邻近效应和行政边界效应,呈现出广泛复杂的空间关联网络和结构形态.然而,不同区域间绿色发展效率“你中有我,我中有你”的空间关联紧密度不高,绿色发展效率的空间关联有待进一步加强;不同区域在空间关联网络中呈现出不同的节点网络关联度,从而拥有截然不同的权力;成渝地区双城经济圈绿色发展效率的空间关联存在4个子群,各子群的空间关联具有明显的“俱乐部”效应,不同区域在子群间及子群内部关联关系中扮演着不同的中间人角色,从而具有不同地位和作用.Based on the related green development index data of 16 regions in the Dual-city Economic Circle of Chengdu-Chongqing Region from 2010 to 2018,this paper uses super efficiency SBM model to measure the green development efficiency level,and then uses social network analysis method to analyze the spatial network correlation characteristics and spatial structure of green development efficiency in the Dual-city Economic Circle of Chengdu-Chongqing Region.The results are shown as follows:The overall green development efficiency level of the Dual-city Economic Circle of Chengdu-Chongqing Region is greatly affected by non-Chengdu-Chongqing dual circle regions,and its change trend takes a phased“V”type fluctuation.The spatial correlation between regions breaks through the geographical proximity effect and administrative boundary effect,and presents a wide and complex spatial correlation network and structural form.However,the spatial correlation of“mutual integration”among different regions is not high,and the spatial correlation of green development efficiency needs to be further strengthened,and the different regions have different degrees of node network association in the spatial association network,so much so that they have different powers.There are four subgroups in the spatial correlation of green development efficiency in the Dual-city Economic Circle of Chengdu-Chongqing Region,and the spatial correlation of each subgroup has obvious“club”effect.Different regions play different intermediary roles in the relationship between subgroups and within subgroups,thus having different positions and roles.
