长江经济带人口城镇化与土地城镇化耦合协调度研究

本文旨在研究长江经济带各省市人口城镇化和土地城镇化耦合协调度,提出建议以期对新时期推进新型城镇化战略和促进长江经济带高质量发展有所帮助。基于2008—2017年长江经济带相关数据,计算长江经济带各省市人口与土地城镇化指数,通过耦合协调度模型,实证检验长江经济带各省市人口城镇化与土地城镇化的协调发展度,以此来综合评价城镇化发展水平和协调程度。结果表明：长江经济带各省市人口城镇化落后于土地城镇化,区域内各省市人口和土地城镇化发展水平和协调程度差异明显,总体上呈现协调发展度逐年上升、增速放缓的趋势,城镇化推进工程绩效明显,但仍待进一步解决矛盾。为促进人口与土地城镇化协调发展,应当以人的城镇化为核心,灵活调整土地政策,完善城市规划,发挥城市圈作用。

Coupling Coordination Degree of Population Urbanization and Land Urbanization in the Yangtze River Economic Belt

The paper aims to study the coupling coordination degree between population urbanization and land urbanization in the provinces and municipalities of the Yangtze River Economic Belt and put forward suggestions to promote the new urbanization strategy and high-quality development of the region in the new period. Based on relevant data of the Yangtze River Economic Belt from 2008 to 2017, the paper calculated the population and land urbanization index of the provinces and municipalities in the region. Through the coupling coordination degree model, the paper empirically tested the degree of coordinated development of population urbanization and land urbanization. This method could comprehensively evaluate the level of urbanization development and the degree of coordination. The results show that: the population urbanization of the provinces and municipalities in the Yangtze River Economic Belt lagged behind the land urbanization. The level of urbanization development and the degree of coordination were significantly different among the provinces and municipalities. Generally, the degree of coordinated development was increasing year by year and the growth rate was slowing down. The performance of urbanization projects was obvious, but the contradictions still need to be resolved. In order to promote the coordinated development of population and land urbanization, we should take population urbanization as the core, flexibly adjust land policies, improve urban planning, and give play to the role of urban circles.
