| 摘 要： | 基于ESDA方法,利用福建省1998年、2002年及2006年各县域人均GDP数据,对福建省县域经济发展水平的空间差异程度进行了分析.结果表明:福建省1998年、2002年和2006年全局Moran′s I指数均达到显著的空间正相关,区域经济发展呈现出明显的空间集聚现象;1998年至2006年,全局Morans′I值有降低的趋势,县域经济差异扩大.福建省经济发展的局部空间集聚现象亦十分显著,"高-高"关联的县域主要分布在闽东南和闽东部分地区,"低-低"关联的县域分布在闽北地区及闽西部分地区.总体上,经济发展水平呈正关联的县域数量远高于呈负关联的县域数量.并提出了解决差异扩大化的可行性建议.

| Abstract: | Based on the method of ESDA,the spatial differences of the regional economic development level of Fujian Province was investigated by using the data of GDP per capita at county level in 1998,2002 and 2006.The results indicated that the global Moran′s I indexes for GDP per capita at county level of Fujian Province reached the significant positive spatial correlation.The spatial agglomerate phenomenon of regional economic development levels appeared on the whole.However,from 1998 to 2006,the global Moran′s I value had a descendant trend,suggesting the enlargement of the prefectural economic difference.Significant local spatial auto-correlation was also found.The counties with the significant "high-high" correlation were mainly distributed in the southeast and east of Fujian Province.While the counties with the significant "low-low" correlation were located in the north and west of Fujian Province.As a whole,the quantity of counties with the positive association was higher than that with the negative association.Suggestions for resolving the difference expansion of regional economy were also proposed. |
