- 摘要:
- 基于地理信息系统（GIS）软件和探索性空间数据分析方法（ESDA），利用陕西省2002—2011年县域人均GDP数据，对陕西省县域经济空间格局演变进行了分析。结果表明：陕西省县域经济发展呈现明显的空间集聚现象，集聚程度在10 a间得到明显加强，热点区主要分布在以志丹县和安塞县为代表的陕北地区。而经济增长空间格局呈现出由随机分布到集聚分布的演变趋势，经济增长热点区域主要分布在陕北地区，且经历了从南向北的迁移过程。虽然陕西省县域经济整体空间差异有所减小，但无论从经济发展水平和经济增长速度来说，陕西省县域经济的空间格局都呈现明显的“北强南弱”局面。最后，将陕西省县域经济空间格局演变的驱动力分为能矿资源开发、经济区位差异和区域发展政策3个方面进行了分析。
- Abstract:
- Based on GIS software and methods of exploratory spatial data analysis (ESDA), this paper took GDP per capita as indicator to study the evolvement of economy in Shaanxi Province at county level from 2002 to 2011. The results showed that the economy in Shaanxi Province at county level was obviously clustered and had a strengthening trend during this period. The hot spots mainly concentrated in north Shaanxi such as Zhidan County and Ansai County. Moreover, the spatial pattern of economic growth showed a trend from random distribution to clustered distribution, and the hot spots also mainly concentrated in north Shaanxi while experiencing a migration from south to north. In conclusion, although the spatial disparity obviously decreased during these 10 years, the spatial pattern of economy in Shaanxi Province still presented a great imbalanced situation in terms of economy or economic growth. Finally, we analyzed the driving force of the evolvement in 3 aspects including mineral resources, geographical locations and development policies.
