摘　　要：经济全球化背景下,城市群区域一体化成为区域空间发展的重要趋势。基于体制机制、区域发展、创新产业、生态环境、基础设施和公共服务等6方面一体化发展,构建城市群区域一体化评价体系,基于统一的框架,比较分析长江经济带5个主要城市群的一体化发展水平与近10年主要变化特征,突出城市群发展侧重与短板,为高质量区域一体化发展提供科学参考。结果发现,长江经济带5个城市群区域一体化发展差距显著,呈现从下游到上游逐渐递减趋势,长三角城市群发展水平最高,中游城市群其次,成渝城市群较低,滇中、黔中两个区域性城市群尚处于起步阶段;近10年来各城市群区域一体化水平均有提升,重点发展内容和提升程度不一,中下游城市群侧重公共服务,上游城市群侧重基础设施建设。基于研究结果,从改善区域一体化发展短板和推进体制机制建设方面提出了长江经济带城市群区域一体化发展的政策建议。In the context of economic globalization,urban agglomeration becomes an important foci and form of territorial development.Based on the perspectives of institutions and mechanisms,development trends,innovative industries,ecological environment,infrastructure provision,and public services,this paper establishes an index system to assess the integration levels of five urban agglomerations in the Yangtze River Economic Belt.This study analyzes how the development levels have changed across different urban agglomerations during the last decade.This paper attemptsto provide scientific references for the high-quality development of urban agglomerations.It is found that the regional integration of five urban agglomerations in the Yangtze River Economic Belt shows a decreasing trend from the downstream to the upstream areas.TheYangtze River Delta Urban Agglomerations has the highest development level,followed by the Triangle of Central China,Chengdu-Chongqing City Group,and the two regional urban agglomerations in central Yunnan Province and central Guizhou Province.For the five dimensions of regional integration,the integration levelof infrastructure development in urban agglomerations is the highest,while that of innovative industries is the lowest.In the past 10 years,there has been significant progress in the urban agglomeration integrated development,but the development content and promotion degrees differ.The middle and lower reaches of urban agglomerations focus on public services,while the upper reaches focus on infrastructure construction.This paper puts forward appropriate policy suggestions on the integrated regional development of urban agglomerations in the Yangtze River Economic Belt from perspectives of short-term improvement and institutional mechanism construction.
