运用GEODA软件中的ESDA探索性空间数据分析方法,以人均GDP为指标,结合变异系数,对山东省近10年来县域经济差异的空间格局进行了分析。结果表明:山东省县域经济差异近10年来逐渐加大;高高型地区空间自相关明显,范围不断扩大,从东部沿海地区向鲁北地区扩散,低低型区域主要集中在鲁西和鲁南地区,后期逐渐向鲁北和鲁中地区扩大;县域经济发展水平呈现出北高南低、东高西低的高低交错空间格局,极化效应明显;热点区主要集中在以济南、青岛为核心的鲁中和沿海地带,还有北翼的黄河三角洲地带,冷点区集中分布在鲁西、鲁西北边缘地带、鲁中南地区。从政府政策、产业基础、区位因素等方面对空间格局的形成原因进行了分析。
By using the ESDA exploratory spatial data analysis method in GEODA software, the per-capita GDP as an index and the coefficient of variation were used to analyze the spatial pattern of county-level economic disparity in Shandong Province in the recent 10 years. The results show that the economic difference between counties in Shandong Province has gradually increased over the past 10 years. The spatial autocorrelation of high-altitude areas has been obviously expanded and expanded from the eastern coastal areas to the Lubei area. The low-low areas are mainly concentrated in Luxi and Lunan Area, and gradually expanded to Lubei and Luzhong areas in the later period. The level of economic development in the county area showed a staggered pattern of highs and lows from north to south and high to low in the east, with obvious polarization effect. The hot spots mainly focused on Jinan and Qingdao Of Luzhong and the coastal zone, there is the north wing of the Yellow River Delta, the cold spot concentrated in Luxi, the northwestern edge of Shandong, Central and Southern Shandong. The reasons for the formation of spatial pattern are analyzed from the aspects of government policy, industrial base and location factors.
