摘要
基于2001—2008年关中—天水经济区相关数据,首先使用人均GDP标准差系数和变异系数考察其县域经济增长的绝对差异和相对差异;其次,通过因子分析法构建和估算了县域经济发展水平综合指数;最后,以县域经济发展水平综合指数为指标进行了空间集聚性和异质性分析。结果表明:2001—2008年县域经济增长差异快速拉大;经济发展水平处于低水平非均衡空间分布状态,二元结构、空间集聚性与异质性、中心—外围模式特征明显。
Base on the 2001-2008 Guanzhong--Tianshui economic zone data, the author firstly investigated the absolute difference and relative difference of economic growth among the counties by using coefficient of Standard Deviation and Coefficient of Variation of per capita GDP; Secondly, the author constructed and estimated the composite index of economic development of the county by employing factor analysis; Finally, the writer analyzed the spatial clustering and heterogeneity, using the composite index of economic development of the county as indicators. The results showed that the difference of economic growth of the county widened rapidly from 2001 to 2008; the economic development level is in a low and non-equilibrium spatial distribution state, the features of the dual structure, spatial clustering and heterogeneity and the center - periphery model were distinctive.
