摘要
推动县域经济高质量发展有利于乡村振兴、新型城镇化等战略的有效落实,也是实现区域一体化的重要支撑.以四川省183个县域为基本空间单元,在构建县域高质量评价指标体系与评价模型的基础上,采用泰尔指数、变异系数、ESDA等方法,对2009、2016、2020年四川省县域高质量发展的时空演化进行分析.研究发现:(1)全省县域高质量发展水平呈上升趋势,区域差异缩小,空间集聚态势减弱.(2)成都平原经济区内部差异主导着全省高质量发展区域差异走向;川南地区和川东北地区内部均衡性较高,发展均质性凸显.(3)遂宁、泸州等四市县域高质量发展水平提升最多,排名上升明显.(4)县域差异悬殊呈减弱趋势,高质量发展县域布局由单核向多核演化,“一干多支、五区协同”战略成效明显.(5)扩散型县域逐步形成了以成都、德阳、绵阳为中心的集聚区,呈“倒斜山”字形结构;极化型县域数量呈增加态势,零散分布在成都平原经济区外围;沉陷型县域多布局在扩散型县域周边地带;传染型县域在范围、数量、程度上时序变化较大.
Promoting high-quality development of county-wide economy is not only conducive to the effective implementation of rural revitalization,new urbanization and other strategies,but also to achieve regional integration of the important support.Taking 183 counties of Sichuan province as basic spatial units,and on the basis of the constructing a county-wide high-quality evaluation index system and evaluation model,and by methods like the Theil index,coefficient of variation,ESDA,an analysis is done of the spatio-temporal evolution of high-quality county development in Sichuan province in 2009,2016 and 2020.The findings are as follows:(1)the county-level high-quality development is on the rise,the regional difference is narrowing,and the trend of spatial agglomeration is weakening;(2)the regional difference of high-quality development in Chengdu Plain Economic Zone leads the trend of regional difference of province-wide high-quality development;The internal balance of south Sichuan and northeast Sichuan is high,and the homogeneity of development is prominent.(3)the four cities of Suining and Luzhou,etc.,had the highest level of high-quality development,and their ranking rose significantly.(4)the strategy of“One stem coupled with many branches,five-district coordination”has achieved remarkable results,(5)the county regions of diffusion type have gradually formed the gathering area with Chengdu,Deyang and Mianyang as the center,taking on a shape of“Inverted slope mountain”;The number of polarimetric counties is increasing and they are scattered in the periphery of Chengdu Plain economic zone,while the subsidence counties are mostly distributed in the periphery of diffusive counties;The range,quantity and degree of the time series of infectious counties vary greatly.
