我国建筑业经济增长的空间分异及驱动因素分析

Spatial Differentiation and Its Driving Factors Analysis of Economic Growth in China Construction Industry

基于2005—2017年我国省域面板数据,运用空间探索性数据分析方法和地理探测器法,分析了我国建筑业经济增长的空间分异格局及驱动因素。结果表明:全国建筑业经济增长具有明显的空间正相关性和较强的区域集聚性,并且这种集聚呈“U”型变化;各区域建筑业经济增长存在显著的空间异质性,且区域差异有扩大趋势;在各类驱动因素中,经济生产总值、利用外资额和从业人员数量等对建筑业经济增长的空间分异有较大的影响,且所有驱动因素的作用力差距逐渐缩小;基础设施投资等驱动因素对建筑业经济增长空间分异具有多重叠加交互作用。

Based on the provincial panel data from 2005 to 2017,this paper uses spatial exploratory data analysis and geographic detection methods to analyze the spatial differentiation and driving factors of economic growth in the construction industry.The results show that:economic growth in the national construction industry has obvious spatial positive correlation and strong regional agglomeration,and this agglomeration has a“U”-type change trend;there is significant spatial heterogeneity in economic growth of the construction industry in various regions,and regional differences have an expanding trend;among the various driving factors,GDP,FDI and the number of employees have a greater impact on the spatial differentiation of economic growth in the construction industry,and the gap between the forces of all drivers is gradually narrowing;drivers such as infrastructure investment have multiple overlapping interactions on the spatial differentiation of economic growth in the construction industry.
