近30年浙江省县域经济空间格局的动态研究

Changes in the spatial distribution of county economy in Zhejiang in recent three decades

以7个时间断面的县域GDP数据为基础,通过相关指标测度和区域重心计算,并借助G IS软件可视化表达,系统分析近30年浙江省县域经济空间格局演变的动态特征。结果表明,近30年来浙江省县域经济差异经历了先缩小后扩大的过程,目前县域经济差异较大,主要来自南北差异;以杭金—金丽高速沿线、环杭州湾和温台沿海三大板块高速增长为特征的全省不平衡发展,打破了县域经济原有相对均衡的空间格局,当前,以杭州、宁波为核心的浙北地区、以义乌为首的金华地区和温台沿海地区已成为浙江县域经济发展的三大优势区域。基于县域经济格局影响因素的变化,提出推动欠发达县市跨越式发展、促进浙江县域经济统筹协调的若干建议。

On the basis of county GDP data of 7 time sections,dynamic characteristics of spatial evolution of county economy in Zhejiang in recent three decades were systematically analyzed by measuring some indexes and the GDP gravity centers with the aid of GIS technology.The results showed that the differences in Zhejiang＇s county economy have experienced a process that enlarged at first and then narrowed in recent three decades,and at present the differences which mainly from north and south are comparatively large;The uneven development characterized by the fast growth of three blocks（i.e.the areas along the expressways of Hangzhou-Jinhua and Jinhua-Lishui,Hangzhou Bay Rim and the coastal areas of Wenzhou and Taizhou） has enlarged the county economy differences of the province,and now three areas including northem Zhejiang area headed by Hangzhou and Ningbo,Jinhua area headed by Yiwu,Wenzhou and Taizhou coastal areas have become advantage areas in county economy development in Zhejiang.In view of the variation of influencing factors of county economic pattern,some suggestions for promoting the striding development of less developed counties and overall coordination of county economy in Zhejiang were proposed.
