摘要
本文利用中国工业企业数据库和中国海关数据库的匹配数据,系统考察了城市群空间功能分工对企业出口增加值的影响。研究发现,城市群空间功能分工对企业出口增加值的影响存在U形特征,即在城市群空间功能分工的初期,较高的城市间交易成本倾向于抑制企业出口增加值;进入成熟阶段以后,企业通过嵌入城市群网络,在规模借用效应和功能借用效应下,偏向于提高出口增加值。本文测算结果显示,中国大约有四分之一城市群已经进入拐点的右侧。进一步研究发现,规模借用效应和功能借用效应仅仅是在小城市企业与大城市的互动中显著,且功能借用效应大于规模借用效应。由此,本文提出突破城市间的行政区划界线,将城市群作为区域经济治理的基本空间单元,加强中心城市的集聚能力,发挥中心城市对小城市企业的辐射作用,提高企业出口增加值。
This paper,based on the matching data of China Industry Business Performance Data and China Customs Database,examines the impact of the spatial function division of urban agglomeration on the value added of firms’exports,which proves to be U-shaped.Specifically,higher inter-city transaction costs tend to suppress the export value of firms in the early stage of spatial function division;and after entering the mature stage,firms can increase the value added of exports under the borrowed size effect and borrowed function effect.The research results show that about one-quarter of China's urban agglomerations have entered the right side of the inflection point.In addition,further research finds that borrowed size effect and borrowed function effect are significant only in the interaction of firms in small cities with large cities,and the borrowed function effect is greater.Therefore,this paper proposes to break the boundaries of administrative divisions between cities,and use urban agglomerations as the basic spatial unit of regional economic governance to strengthen the agglomeration capacity of central cities.By this means,we can give full play to the radiating effect of central cities on firms in small cities,reveal the deep level of interactive integration between cities and firms in small cities,and increase the value added of firms’exports.
