协同视阈下淮河生态经济带绿色高质量发展及其空间特征研究

基于淮河生态经济带28座设区市的面板数据，在协同视域下利用容量耦合协调模型从经济、社会、生态3个层面对淮河生态经济带绿色高质量发展水平进行测度，并利用莫兰指数揭示其绿色高质量发展的空间特征。研究表明:淮河生态经济带各区域绿色高质量发展水平及其经济、社会、生态三大子系统的发展水平均呈明显的上升趋势；从区域平衡性看，淮河生态经济带内部三大区域绿色高质量发展水平差异显著，呈东部海江河联动区、北部淮海经济区、中西部内陆崛起区递减态势；从发展充分性看，各地区经济子系统和社会子系统的发展情况呈现时空一致性，但其与生态子系统的发展情况具有显著差异；从空间集聚特征看，淮河生态经济带绿色高质量发展水平及其社会子系统空间集聚不显著，而经济子系统和生态子系统则呈现明显的正向自相关特征。基于此，提出相关对策建议，以期推进淮河生态经济带绿色高质量发展。

Green and high-quality development and spatial characteristics of Huaihe Eco-economic Belt from synergy perspective

Based on the panel data of its 28 districts and cities, the green and high-quality development level of Huaihe Eco-economic Belt is measured from the three aspects of economy, society and ecology by using the coupling coordination degree model from the synergistic perspective. The spatial characteristics of the green and high-quality development is revealed by using the Moran Index. The research results are as follows: The green and high-quality development level in the districts and cities of Huaihe Eco-economic Belt and the development level of three subsystems of economy, society and ecology have obvious increase trend. From the regional equilibrium, the green and high-quality development levels in three areas of Huaihe River Eco-economic Belt have significant differences, with a decrease trend from the sea-river-lake linkage areas in the east to the Huaihai Economic Zone in the north to the inland rising areas in the middle and west. From the development degree, the development situations of the subsystems of economy and society in various districts and cities are temporally and spatially consistent, but they are significantly different from those of the subsystem of ecology. From the spatial aggregation, the green and high-quality development level in Huaihe River Eco-economic Belt and the subsystem of society have no obvious spatial aggregation, while the subsystems of economy and ecology Zone have significant positive autocorrelation. Accordingly, some policy countermeasures are proposed so as to promote the green and high-quality development in Huaihe River Eco-economic Belt.
