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。
From the perspective of new economic geography, this paper uses the panel data of 277 cities in our country from 2003 to 2013 to construct the spatial Dobbin model. By using three kinds of spatial weight matrixes such as distance decay, economic distance and inverse distance square, this paper tests the service industry and subdivision service industry The impact of agglomeration on technological progress in local and neighboring cities. Consistency of the three spatial weight matrices shows that: (1) Producer service and public service agglomeration have significantly promoted technological progress in urban areas in the region, while agglomeration of consumer service industries has inhibited technological progress; at the regional level, producer services The effect of agglomeration of public service industry on the technological progress in the eastern, central and western regions shows a U-shaped structure. (2) In terms of spillover effect, agglomeration of productive and public services in the western region shows significant spatial spillover effect on the technological progress of the neighboring cities. However, at the national level, the combined effect of positive spillover and agglomeration in the eastern and central regions Under the spillover effect is not obvious.
