摘　　要：县域经济在国民经济中的重要性日益凸显。研究县域经济空间差异,指导县域因地制宜、走可持续发展道路。以山东省100个县域为研究单元,采用崔—王指数、变异系数、因子分析法和探索性空间分析方法,对山东省县域经济差异的时空演化特点进行了初步分析。结果表明:2006—2018年,山东省县域经济差异呈波动性下降,但变化幅度较小;山东省县域经济存在空间集聚效应,呈近似倒“S”型的分布;县域经济空间自相关显著综合经济实力高值区与人均GDP高值区在空间上相契合;县域经济发展整体呈现出东北向西南逐渐减弱的趋势,低水平发展县域在空间上明显集聚,存在俱乐部趋同现象;鲁东和鲁中地区是经济发达区,形成了以济南—青岛为主的双核心发展模式,经济发展水平高且发展速度快;在局部空间自相关分析中,山东省县域经济发展存在较大差异,高—高聚类在12年中未发生大的变动,低—低聚类县域个数逐渐减少。The importance of county economy in the national economy has become increasingly prominent.The spatial differences of county economy are studied to guide the county to adapt to local conditions and take the path of sustainable development.By taking 100 counties in Shandong Province as the research unit,the Cui-Wang index,coefficient of variation,factor analysis,and exploratory space analysis were used to analyze the characteristics of the spatial and temporal evolution of county economic differences in Shandong Province.The results showed that the differences in county economy in Shandong Province fluctuated from 2006 to 2018,but the change was small.There was a spatial agglomeration effect in the county economy of Shandong Province,which showed an approximately inverted S-shaped distribution in space and the correlation was significant.The high-value areas of comprehensive economic strength coincided with the high-value areas of per capita GDP.The county-level economic development as a whole is gradually weakening from the northeast to the southwest.The low-level development counties are clearly clustered in space and there is club convergence.Eastern Shandong and Central Shandong are economically developed areas,and have formed a dual-core development model,mainly Jinan-Qingdao,with a high level of economic development and rapid development.In the local spatial autocorrelation analysis,the economic development of counties in Shandong Province exists.The big difference is that the high-high clustering has not changed much in 12 years,and the number of low-low clustering counties has gradually decreased.
