摘　　要：提高城市发展质量是现阶段经济高质量发展的应有之义,中国城镇化进程中的城市蔓延已成为影响城市高质量发展的重要因素。本文利用2004—2017年中国285个地级及其以上城市面板数据,实证考察了城市蔓延与绿色全要素生产率之间异质性关系。研究发现:①城市适度蔓延对绿色全要素生产率起显著提升作用,蔓延过度则呈现抑制效应或者影响不明显;②就人口集聚的区域差异而言,城市蔓延对东部地区促进作用突出,而对中西部地区更多表现出抑制效应;③此外,随着经济超过最优集聚区间,两者之间的反方向关联变为同向关系,进一步发现,两者之间显著存在基于制造业集聚的“倒U型”门槛效应,而在服务业集聚程度较高的城市,城市蔓延的促进效应并不显著。本文深化了对城市蔓延影响城市绿色发展基本规律的认识和理解,为城市高质量发展的“顶层设计”提供了有益的参考,对中国正在推进的以中心城市引领城市群和新型城镇化战略也有着启示意义。Improving the quality of urban development is the essence of high-quality economic development at the present stage.Urban sprawl in the process of urbanization in China has become an important factor that affects the quality of urban development.Using panel data of 285 cities in China from 2004 to 2017,this study empirically investigated the heterogeneous relationship between urban sprawl and green total factor productivity.The research found that:(1)Moderate urban sprawl improved green total factor productivity,while excessive urban sprawl inhibited or did not significantly affect green total factor productivity;(2)Considering regional differences of population agglomeration,urban sprawl had a prominent promoting effect on green total factor productivity in the eastern region,while having more inhibitory effects on the central and western regions;(3)As the economy exceeded the optimal agglomeration thresholds,the inverse correlation became a co-directional relationship.Furthermore,there was a significant inverted U-shaped threshold effect based on manufacturing agglomeration.However,in cities with a higher degree of service industry agglomeration,the promotional effect of urban sprawl is not significant.This study deepens the understanding of the basic pattern of urban sprawl affecting green development of cities.It provides a beneficial reference for the top-level design of high-quality urban development and is of significance for China’s promotion of leading urban agglomeration with central cities and new urbanization strategy.
