摘要
实现城市产业结构与服务功能协同升级是推动以人为核心的新型城镇化的迫切要求和关键举措.文章综合运用熵权法、耦合协调度模型、Kernel密度估计法、马尔科夫链模型、Dagum基尼系数及分解等方法展开实证分析,以揭示2010-2021年中国284个城市产业结构与服务功能协同升级的时空演化特征.结果显示:全国及四大区域城市产业结构与服务功能协同水平均呈现稳步上升趋势,但区域异质性明显;中国城市产业结构与服务功能协同升级呈现出"整体水平提升、离散趋势多样、梯度形态不一"的分布特征,层级稳定性和"俱乐部趋同"现象明显,空间溢出效应是影响其演变趋势的重要因素;中国城市产业结构与服务功能协同升级的总体空间差异呈现下滑态势,超变密度、区域间差异、区域内差异的年均贡献率依次降低.
Abstract
Achieving coordinated upgrading of urban industrial structure and service func-tions is an urgent requirement and key measure for promoting people-oriented new urbaniza-tion.This paper comprehensively applies methods such as entropy weight method,coupling coordination degree model,Kernel density estimation method,Markov chain model,Dagum Gini coefficient,and decomposition to carry out empirical analysis,revealing the spatial-temporal evolution characteristics and regional differences of the Coordinated Upgrading of industrial structure and service functions in 284 cities in China from 2010 to 2021.The results show that:The coordination level of urban industrial structure and service functions in the whole country and the four major regions is steadily increasing,but the regional heterogeneity is significant;The Coordinated Upgrading of industrial structure and service functions in Chinese cities presents a distribution characteristic of"overall level improvement,diverse dispersion trends and uneven gradient forms",with obvious hierarchical stability and"club convergence"phenomenon,and spatial spillover effect is an important factor affecting its evolution trend;The overall spatial differences of coordinated upgrading of industrial structure and service functions in Chinese cities showed a downward trend,and the annual contribution rates of sup er-variation density,inter-regional differences,and intra-regional differences decrease in turn.
