空间视角下生产性服务业集聚对城市土地集约利用的影响研究

The Impacts of Productive Services Agglomeration on the Intensity of Urban Land Use from the Spatial Perspective

研究目的:从空间视角研究生产性服务业集聚对中国城市土地集约利用的决定作用,为新型城镇化建设进程中合理安排城市产业布局、促进土地利用方式转变、实现城市经济和土地集约利用协同发展提供新思路。研究方法:空间计量分析法。研究结果:中国城市间生产性服务业集聚和土地集约利用在地理分布上具有显著空间关联性;全国层面,生产性服务业通过专业化集聚、多样化集聚产生的技术外溢效应和集聚规模产生的规模经济效应显著提高了城市土地集约利用水平;分板块层面,生产性服务业多样化集聚和集聚规模对城市土地集约利用的正向效应呈现东、中、东北、西部板块依次递减现象,而专业化集聚对城市土地集约利用的技术外溢效应在西部地区更明显。研究结论:提升生产性服务业集聚水平、促进产业结构优化和人口集聚有利于中国城市集约利用土地资源。

The purpose of this study is to investigate the effect of productive services clustering on the intensity of urban land use in China from the spatial perspective, it is significant to provide suggestion for government to arrange reasonable industrial layout, to promote the conversion of urban land use, and to achieve collaborative development of urban economy and land intensive use in the process of new urbanization in China. Methods of principal component analysis and spatial econometrics analysis were employed. The results indicate that： 1）it exists significant spatial association between the productive services agglomeration and intensive urban land use;2）on the national level, there are significantly positive effects of productive services agglomeration on the intensive urban land use through the technology spillover effect by specialized agglomeration, diversification agglomeration and the economies of scale by agglomeration scale;3）on the regional level, the positive effects of diversification agglomeration and agglomeration scale on the eastern, central, northeast and west areas present a phenomenon in descending order, moreover, the technology spillover effect of specialized agglomeration is more evident in the west than that in the other three regions of China. The paper concludes that enhancing the level of productive services clustering, optimizing the industrial structure, and promoting population agglomeration are all helpful to the intensity of urban land use in China.
