摘　　要：中心-外围城市间污染控排效应的空间发散引致了减排“孤岛”现象的发生,制约了区域绿色高质量发展。基于中心-外围空间结构构建污染控排空间效应理论模型,从城市间生产活动的规模报酬异质性视角解释减排“孤岛”的形成动因,结合2003—2016年中国279个地级市的面板数据,利用空间网络分析和空间计量模型对理论演绎结果进行实证检验。研究结果表明:在规模报酬递增的作用下,单位污染物排放的产出水平随着城市中心度的提升而提升,中心城市控排效应更为明显,减排“孤岛”由此形成;城市控排效应空间正相关,城市中心度越高,其受到其他城市正向空间溢出的效果就越显著,减排“孤岛”被进一步强化;中心-外围城市间的主导产业异质性及由此产生的产业关联是控排效应空间发散的根本原因。因此,需要接受仅凭经济系统内在力量难以自动弥合中心-外围城市减排“鸿沟”的基本现实。但是,可以从推动外围城市绿色产业转型、加速中心城市绿色技术溢出、提升中心-外围城市经济合作等角度优化政策供给,最大限度推进排污强度的相对收敛。The spatial divergence of pollution control and emission effects between central and peripheral cities has led to the occurrence of emission reduction“islands”,which restricts the high-quality development of regional green development.Based on the center-periphery spatial structure,a theoretical model of pollution control and emission spatial effects is constructed to explain the reasons for the formation of emission reduction“islands”from the perspective of heterogeneity in scale returns of production activities between cities.Combined with the panel data from 279 prefecture level cities in China from 2003 to 2016,this paper makes use of spatial network analysis and spatial econometric models to provide empirical tests for the theoretical deduction results.The findings show that under the effect of increasing returns to scale,the output level of unit pollutant emissions increases with the increase of urban centrality,and the emission control effect of the central cities is more obvious,leading to the formation of emission reduction“islands”.The spatial urban emission control effect is positively correlated,the higher the centrality of the city,the more significant its positive spatial spillover effect from other cities;and the“island”of emission reduction is further strengthened.The heterogeneity of the dominant industries between central and peripheral cities and the resulting industrial associations are the fundamental reasons for the spatial divergence of emission control effects.Therefore,it is necessary to accept the basic reality that it is difficult to automatically bridge the emission reduction gap between central and peripheral cities solely based on the internal strength of the economic system.However,policy supply can be optimized from the perspectives of promoting the transformation of green industries in the peripheral cities,accelerating the spillover of green technologies from the central cities,and enhancing the economic cooperation between central and peripheral cities,in order t
