服务业集聚与城市技术进步

Service agglomeration and urban technology development

本文从新经济地理学角度,利用2003-2013年我国277个城市面板数据,构建空间杜宾模型,通过距离衰减、经济距离和逆距离平方三种空间权重矩阵,检验了服务业及细分服务业集聚对于本地和临近城市技术进步的影响。三种空间权重矩阵一致表明:(1)生产性服务业、公共服务业集聚显著促进了本地区城市技术进步,而消费性服务业集聚抑制了技术进步;从地区层面来看,生产性服务业、公共服务业集聚对东部、中部、西部技术进步的集聚效应呈U型结构。(2)在空间溢出效应上,西部地区生产性和公共服务业集聚对临近城市技术进步显示了显著的空间溢出效应,但全国层面、东部地区和中部地区在正向溢出和集聚阴影的共同作用下,空间溢出效应不明显。

Based on urban panel data from 2003 to 2013 in China,This paper estimates a spatial Durbin model to examine the relationship between service sector including its sub-sectors and urban technology development. The results are robust to three different spatial weight matrixes and indicate as follows. Firstly,producer service and public service agglomeration can significantly promote local urban technology development,while consumer service agglomeration inhibits technology development. From the view of region,the agglomeration effects of producer service and public service manifest a U-shaped structure. Secondly,producer and public service agglomeration show obvious spatial spillover effects in western regional. On account of positive spillover effects and agglomeration shadows,spatial spillover effect is not obvious in national level,eastern region and central region.
