环渤海地区县域经济发展时空分异研究

以县域为基本研究单元,应用统计分析法和空间分析法,以人均地区生产总值为指标,分析1996—2009年间环渤海地区县域经济的时空分异特征。结果表明,环渤海地区经济实力不断增强,产业结构呈现高级化趋势;县际经济发展水平差距大,部分县域人均GDP处于极端高水平;1996—2009年间,县域人均GDP的绝对差异增大而相对差异波动性缩小,省间差异是区域差异的主要组成部分;人均GDP空间自相关显著,经济发展热点区和冷点区的空间集聚特征增强。基于1996年各县人均GDP及1996—2009年间人均GDP增长差异,将环渤海地区划分为基础好增长较快型、基础中等增长较快型等6种类型。

Study on Spatial Characteristics and Evolution Pattern of Economic Development at County-Scale in the Area along Bohai Rim in China

Regional economic disparity has long been an interesting topic of academic research on regional development economics in every country.Based on GIS and spatial analysis,this paper carries out a preliminary study on the spatial characteristics and evolution pattern of GDP per capital along the Bohai rim at county-scale.Some conclusions are summarized as follows:(1) GDP per capital in the area along Bohai rim has been increasing quickly since 1996,and it is reach 4.15×104 yuan with the GDP per capital in some countries at high level.(2)There is extreme disparity of the regional economic development at county-scale,and underdeveloped areas are the main forms while developed areas are concentrated in metropolitan areas and coastal areas.(3)The distribution pattern has not changed much during 1996—2009,but absolute difference has been steadily expanding while relative difference has been increased and then reduced fluctuately,there is significantly spatial autocorrelation of GDP per capital,hotspots and coldspots of economic development clustered in several areas.(4) Based on the level of GDP per capital in 1996 and increase speed of GDP per capital between 1996 and 2009,six increase categories of regional economic development are divided.
