　　运用空间计量方法,利用甘肃省1990?2010年县域人均GDP数据,对甘肃省县域经济增长空间差异的变化趋势、特征与成因进行了初步探索.结果表明：甘肃省县(市、区)域经济增长具有明显的空间关联特征,甘肃省经济增长表现出以2000年为分界点的两个阶段,且在其子区间上都具有明显的“俱乐部趋同”现象；采用CSDA方法对甘肃省趋同速度进行测算得出,1990?2010年其为1.77%,1990?2000年比2001?2010年快2.21%；运用核密度估计法分析表明甘肃省的经济增长正在由单核转变为多核,在空间上正在由河西走廊转向陇东地区.

The spatial econometric model was used to make a preliminary exploration into the changing trend of county-level economic growth, spatial differences and features and the causes of formation based on the county-level per capita GDP of Gansu Province during 1990?2010. The results demonstrate that there existed an obvious spatial correlation characteristic of county-level economic growth of Gansu Province; the growth was divided into two distinct stages by the year of 2000 and the two subintervals both showed an obvious club convergence phenomenon. Furthermore, the general speed of convergence of Gansu Province during 1990?2010 was calcualted to be 1.77% by using the CSDA method. However, the speed of convergence before 2000 was 2.21% faster than that after 2000. Finally, the kernel density estimation indicates that the economy growth of Gansu has been transforming from a single core to multiple cores and spatially moving from the Hexi region to the Longdong region.
