In the process of rapid development of economic globalization and regional integration, the importance of urban agglomeration has become increasingly prominent. It is not only the main carrier for countries and regions to participate in international competition, but also the main place to promote regional coordination and sustainable development. Coordinated economic, environmental, tourism and traffic development is very necessary for sustainable regional development. However, the existing literature lacks research on coupling coordination of the Economy-Environment-Tourism-Traffic (EETT) system in urban agglomeration. In this study, in order to fill this gap, we establish the index system from four dimensions of economy, environment, tourism and traffic, and select the influencing factors from the natural and human perspectives to exam the spatio-temporal changes and influencing factors in the coupling coordination of the EETT system using an integrated method in the Middle Reaches of Yangtze River Urban Agglomerations (MRYRUA), China. The results indicate that the coupling coordination degree of the EETT system transitioned from the uncoordinated period to the coordinated period, while it showed an increasing trend on the whole from 1995 to 2017. The spatial agglomeration effect has been positive since 2010, while "High-High" and "Low-High" agglomeration regions were transferred from the east to the south. Land used for urban construction as a percentage of the urban area and vegetation index has a great impact on the coupling coordination degree. These results provide important guidance for the formulation of integration and coordinated development policy in the MRYRUA, and then increase China's international competitiveness by improving the contribution of urban agglomerations to GDP.
在经济全球化和区域一体化快速发展的过程中，城市群的重要性日益凸显。城市群不仅是国家和地区参与国际竞争的主要载体，也是促进区域协调和可持续发展的主要场所。协调经济、环境、旅游和交通发展对于可持续的区域发展是非常必要的。然而，现有文献缺乏对城市群经济-环境-旅游-交通（EETT）系统耦合协调的研究。在这项研究中，为了填补这一空白，我们从经济、环境、旅游和交通四个维度建立了指标体系，并从自然和人为两个角度选择了影响因素，采用综合方法考察了中国长江中游城市群（MRYRUA）EETT 系统的耦合协调时空变化及其影响因素。结果表明，EETT 系统的耦合协调度从失调期过渡到协调期，整体上从 1995 年到 2017 年呈增长趋势。2010 年以来，空间集聚效应一直为正，“高高”和“低高”集聚区域从东部转移到南部。城市建设用地占城市面积的比例和植被指数对耦合协调度有很大影响。这些结果为 MRYRUA 制定一体化和协调发展政策提供了重要指导，通过提高城市群对 GDP 的贡献，提高中国的国际竞争力。
