整合多部门经济模型、偏离份额分析和空间自相关等方法模型,分析了1996—2014年徐州都市圈产业结构转型对经济增长贡献的时空异质性特征,并揭示了驱动经济增长的产业作用。结果表明:徐州都市圈产业结构转型对经济增长贡献呈减弱之势,且空间相对差异呈拉大之势;产业结构转型的经济增长效应呈现由市区向外围递减的核心边缘型空间格局,与中心城市产业结构层次高而外围县域低的空间分布具有一致性;空间关联上,HH型县域逐渐向豫东、皖北地区集中,LL型县域逐渐向京沪铁路线以东地区集聚,第二产业是驱动整个都市圈空间两极分化的主要动因;核心区域第二、三产业的结构推动效应在降低而竞争优势增强,而外围地区第三产业的结构推动效应在增强而竞争优势在减弱,产业结构合理化更益于外围经济增长。
This paper analyzes the spatial and temporal heterogeneity of the contribution of industrial structure transformation in Xuzhou metropolitan circle to the economic growth from 1996 to 2014 and reveals the industrial role of economic growth driven by the integration of multi-sector economic model, deviation from share analysis and spatial autocorrelation. The results show that: the transformation of industrial structure in Xuzhou metropolis circle contributes less to the economic growth, and the relative difference in space is widening; the economic growth effect of industrial restructuring presents the core marginal spatial pattern decreasing from the urban periphery to the periphery; and In the spatial correlation, the HH type county gradually converges to the east of Henan and northern Anhui, while the LL type county gradually converges to the east of the Beijing-Shanghai railway line, and the second Industry is the main driving force for the polarization of space in the entire metropolitan area. The structural impelling effect of the secondary and tertiary industries in the core region is reduced while the competitive advantage is enhanced. However, the structural impelling effect of the tertiary industry in the peripheral regions is enhanced and the competitive advantage is weakened. The industries Rationalizing the structure is more conducive to the external economic growth.
