采用主成分和ESDA技术相结合的分析方法,以县级行政区(县、区、市)为研究单元,以2000年、2009年的县域经济数据为基础数据,对贵州省10年来的县域经济实力差异进行分析。结果表明:贵州省县域经济实力差异显著,并有所扩大;黔西地区县域经济实力明显增强;区域总体呈“凸”字型发展格局;以贵阳为中心的圈层结构初步形成;县域经济发展水平与交通状况显著相关;较强型县域的数目增多,空间集聚范围扩大;县域经济实力存在显著的空间正相关,具有地理上的集聚特征;经济发展的二元结构严重,整体水平偏低;形成了以贵阳为中心的经济发达区和黔东、黔南经济落后地带区;经济发展的空间扩散效应增强,极化效应减弱,但县级市的极化效应仍很突出。
Based on the county-level administrative districts (counties, districts and cities) as the research units and the county-level economic data of 2000 and 2009 as the basic data, the paper analyzes the county-level economic strength of Guizhou Province in the past 10 years Differences were analyzed. The results show that the economic strength of counties in Guizhou Province is significantly different and has been widened; the economic strength of counties in Qianxi Prefecture has been obviously enhanced; the overall pattern has the pattern of “convex ”; the circle structure with Guiyang as the center has been initially formed; The level of economic development is significantly related to traffic conditions; the number of stronger counties increases, the scope of spatial agglomeration is expanded; the economic strength of counties has significant spatial positive correlation with geographical agglomeration characteristics; the dual structure of economic development is serious with the overall level of deviation Low; forming an economically developed area centered on Guiyang and an economically backward area in Qiandong and Qiannan regions; the spatial diffusion effect of economic development is enhanced and the polarization effect is weakened, but the polarization effect in county-level cities is still outstanding.
