摘要
以2005年广东省87个县(市、区)级区域为研究对象,选取总人口、国民生产总值等8个指标作为评价因子,通过因子分析和主成分分析法获得各县级单元经济实力综合得分。对综合得分为变量进行空间自相关分析,计算得出全局相关Moran's值和LISA值。结果显示:广东省的县域经济具有明显的空间集聚特征,86.21%的县市经济表现为空间正相关,但仍有少部分县市的经济发展存在异质性。
Total population,GDP and other 8 indicators were selected as the evaluation indices,composite scores for economic of 87 counties （cities,districts） in Guangdong Province were calculated through factor analysis and principal component analysis.Moran＇s value and LISA value were calculated by spatial autocorrelation analysis based on composite scores.The results showed that：economy presents major positive spatial autocorrelation in Guangdong,and the region economy centralization and economy area was obvious,the economy of 86.21% Counties or Cities are positive spatial autocorrelation,and the economy of minority counties or cities are negative local spatial autocorrelation.
