剖析1999—2017年江苏省54个县域经济格局空间演化过程,多维识别分异因子交互影响下县域经济分异机制. 研究表明:全省县域经济结构由“哑铃型”转化为“梭型”,全局空间集聚性逐年增强,始终呈南高北低“俱乐部”集聚; 落后市县阻滞效应减弱,苏南形成以无锡市辖区、苏州市辖区为极核的经济增长放射圈层,苏北形成以淮安、沭阳等经济发展断点为核心的连片滞缓区. 现阶段县域经济发展瓶颈在于南北经济辐射带的稳定连通输送而非对苏北地区孤立外援式扶持; 县域经济发展整体为显著的区位资源主导型,苏南地区为路网密度、地形起伏度、人均住房建筑面积多要素综合主导型,苏中地区为水资源丰度和恩格尔系数双要素协同主导型,苏北地区为交通建设主导型. 县域经济的空间分异机制盘根错节,交互探测能深入明晰因子功能,确保精准实施差异化发展对策.

This paper aims to analyze the spatial evolution process of the 54 counties economic structure in Jiangsu Province from 1999 to 2017 and to multi-dimensionally identify the internal mechanism of spatial differentiation of county space. The research shows:Firstly,the county’s economic structure is transformed from“dumbbell type”to“shuttle type”. The global spatial agglomeration is increasing year by year,and always presents the club gathering which is high in the south and low in the north. Secondly,the backward counties retarding effect is weakened. The southern part of Jiangsu Province forms the economic growth radial layer of Wuxi municipality and Suzhou municipality,while the northern part has formed a contiguous development slowly area with Huai’an and Shuyang as the core of economic development breakpoints. At present,the bottleneck of the sustainable development of the county economy lies in the stable and connected transportation of the north-south economic radiation belt rather than merely focusing on the support of isolated foreign aid in the northern Jiangsu region. Thirdly,the overall development level of county economy in Jiangsu is characterized by a prominent resource-oriented economy. The southern part of Jiangsu is characterized by multiple constraints on road network density,topographic relief,and per capita housing construction area. The central part is characterized by two-element coordinated economy of water resource abundance and Engel coefficient,and the northern part is characterized by a traffic-oriented economy. Interactive detection can clarify the function of factors so that to ensure the precise implementation of differentiated development strategies.
