研究长江经济带中国式现代化时空差异及分布演进有利于优化长江经济带重大生产力布局，引导资金、技术、劳动密集型产业从长江经济带下游向中上游、从中心城市向腹地有序转移，促进其欠发达地区形成新的增长极和区域内生发展活力。根据中国式现代化的5个特征构建了中国式现代化评价指标体系，采用熵值法计算出2005～2021年长江经济带11个省域的中国式现代化综合评价指数。在此基础上，运用空间分位技术模拟中国式现代化的梯度分组，借助Dagum基尼系数法对中国式现代化水平的相对差距进行测度，基于核密度估计法刻画中国式现代化水平的绝对差距和动态演进特征。得到主要结论:(1)长江经济带中国式现代化水平呈现出自东向西梯度逐渐下降的空间格局。(2)总体而言，长江经济带中国式现代化水平在持续提升，中国式现代化非均衡情形趋于弱化。(3)经济较发达地区内部及其与经济欠发达地区之间的相对差距都较大，但呈现出缩小趋势;同时，经济较发达地区中国式现代化水平存在极化现象，绝对差距呈现出缩小趋势。该研究可以为定量分析中国式现代化水平以及测度区域内和区域间中国式现代化水平的相对差距和绝对差距提供重要参考。
A Study on the Spatio-temporal Disparities and Evolution of Distribution of Chinese-style Modernization in the Yangtze River Economic Belt
Exploring the spatio-temporal disparities and the evolution of Chinese-Style Modernization(CSM)distribution in the Yangtze River Economic Belt(YREB)is instrumental in optimizing the significant productive forces layout within the region.This endeavor entails systematically guiding the transfer of capital,technology,and labor-intensive industries from the downstream to the midstream and upstream regions of the YREB,as well as from central urban areas to the hinterland.The objective of this study was to catalyze the formation of new growth poles in underdeveloped areas of the YREB,thereby fostering indigenous development vitality.Constructing an evaluation index system for CSM based on five major characteristics,Ⅰ employed the entropy method to calculate the comprehensive evaluation index for CSM in the 11 provincial regions of the YREB from 2005 to 2021.Subsequently,leveraging spatial quantile technique,Ⅰ simulated the gradient grouping of CSM.Utilizing the Dagum Gini coefficient method,Ⅰ measured the relative disparities in the level of CSM.Additionally,based on the kernel density estimation method,Ⅰ characterized the absolute disparities and dynamic evolutionary features of CSM level.The main findings were as follows:(1)From the eastern to the central,and then to the western regions,the level of CSM in the YREB exhibited a conspicuous gradient descent trend.(2)Overall,the level of CSM in the YREB was consistently on the rise,with the non-uniform development scenario tending to weaken.(3)Relative disparity values were relatively high within economically developed regions and between economically developed and underdeveloped regions,but the values exhibited a trend of reduction.Simultaneously,economically developed region in the YREB manifested a polarization phenomenon in the level of CSM,with absolute disparity showing a diminishing trend.This paper provided a crucial reference for the quantitative analysis of CSM and the measurement of relative and absolute disparities in CSM within and between the regions.
