摘要
以四川省1998年和2016年180个县域的人均GDP现价数据为基础,结合GIS空间分析方法,从四川省县域经济差异的总体变化、经济类型的结构、数量和空间变化角度出发,对四川省县域经济差异变化进行分析,结果表明:四川省县域经济发展水平的绝对差异在扩大,相对差异在减小。县域经济变化以向上发展为主,跳跃式发展的县域占个别,区域经济差异结构由"扁坛"状的分布结构演化为近似"瓶状"结构,四川省不平衡的经济差异模式呈减弱趋势。四川经济差异在空间上呈现中部、东部、西部的经济空间差异梯度格局;经济增长格局向南、向东发展,由"一中心两极"转变为多中心发展的空间格局。
Based on the current price data of per capita GDP of 180 counties in Sichuan province in 1998 and 2016, the economic inequality of Sichuan province is analyzed by using the method of GIS spatial analysis, from the view of the structure, quantity and spatial change of economic types. The results show that the absolute ine- quality in the development level of county economy in Sichuan province is enlarging and the relative difference is decreasing. The regional economic difference structure evolves from the ＂flat altar＂ to approximate ＂bottle - like＂ structure, and the unbalanced economic difference pattern of Sichuan province shows a weakening trend. The eco- nomic spatial difference of Sichuan presents a gradient pattern of the economic spatial difference in central, east- ern and western regions. The pattern of economic growth has developed to the south and east and shifted from ＂one center and two poles＂ to a spatial pattern of multi - center development.
