摘要:
以四川省183个县域为基本单元,选取人均GDP指标,结合区域差异的统计方法和空间自相关方法研究了1998-2016年四川省县域经济差异的时空演变特征,结果表明:四川省县域经济绝对差异呈扩大趋势,相对差异呈波浪式减弱态势.低于四川省人均GDP平均水平的县域是县域经济数量结构的主体地位将长期保持.四川省县域经济发展水平和增长速度都表现出明显的空间差异性,经济发达的县域集聚在成都平原和安宁河谷平原的腹地,形成了中间高四周低的空间差异格局.

Abstract:
Based on the per capita GDP of 183 counties in Sichuan province from 1998 to 2016, the spatial and temporal evolution characteristics of the county economic inequality of the province were studied with the traditional statistical methods and spatial autocorrelation analysis methods in combination. The results showed that in the 18 years mentioned above, the absolute difference of county economy expanded, and the relative difference diminished in a fluctuating way. Counties with a per-capita GDP lower than the average of Sichuan constituted the principal part of the economic number structure, and this situation would not change in a long time to come. The development level and growth rate of Sichuan county economy showed an obvious spatial heterogeneity and the economically developed counties were clustered in the hinterland of Chengdu plain and Anning Valley plain, forming a spatial pattern of developed counties in the central region surrounded by relatively backward counties.
Key words:  county economy  spatial and temporal evolution  Sichuan province
