基于2001-2008年数据，用标准差、变异系数和因子分析研究关中—天水经济区县域经济差异，发现差距扩大、空间分布不均衡且呈中心-外围模式。
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.
