长三角产业一体化高质量发展测度及时空演变规律

Measurement for the high-quality development of industrial integration in the Yangtze River Delta and its spatio-temporal evolution law

紧扣协议分工理论与高质量发展五大理念,采用面板熵权法测算了2007—2020年长三角41个城市产业一体化高质量发展水平,并综合空间探索性分析方法与空间马尔科夫方法揭示了长三角地区产业一体化高质量发展的空间分布特征与时空动态演变趋势。研究发现:①长三角地区的产业一体化、高质量发展及产业一体化高质量发展综合水平总体呈逐步上升趋势,且高质量发展水平高于产业一体化水平;②产业一体化高质量发展水平在空间上呈现“直辖市/省会城市高、东部高于西部、中心城市高于边缘城市”的特征;③各地区的产业一体化高质量发展具有空间依赖性,当周边城市等级高于本地区时,则会拉动本地区产业一体化高质量发展水平的提升,具有“扩散效应”;④长三角地区产业一体化高质量发展的聚类模式相对稳定,短期内不易改变。

This paper aimed to reveal the spatial distributions and spatial-temporal dynamic evolutions for the high-quality de-velopment of industrial integration in the Yangtze River Delta using the spatial exploratory analysis method and spatial Markov Chain,with the high-quality development levels of industrial integration measured by the panel entropy weight method on 41 cities in the Yan-gtze River Delta spanning the years 2007 to 2020,closely following the Agreement Division of Labour Theories and five concepts for de-velopment.The results showed that:①The overall trends of industrial integration,high-quality development,and the comprehensive in-dex level for the high-quality development of industrial integration in the Yangtze River Delta was gradually increasing,and the level of high-quality development was higher than that of industrial integration.②The spatial distribution of the high-quality development level of industrial integration formed a pattern of“municipality and provincial capital cities were higher,the east was higher than the west,and the central city was higher than the peripheral city”.③The high-quality development of industrial integration in each region was spatially dependent,and the local high-quality development level of industrial integration was pulled up when the rank of the sur-rounding cities was higher than that of the local,with a“diffusion effect”.④The clustering pattern for the high-quality development of industrial integration in the Yangtze River Delta was relatively stable and difficult to change in the short term.
