中文摘要：

国家重视长江经济带的规划建设非始今日，而是基本上十年就有一次，这充分说明了长江经济带在全国特别重要的战略地位，由此也使得研究长江经济带的成果特别丰富。通过对国内外宏观发展态势和长江经济带现状特征、存在问题、发展态势的总体把握，植根以往区域发展领域既有的创新性理论与方法研究积累，以及长江经济带相关研究基础，长江经济带未来发展的新思路应立足于三大视角：基于流域视角的长江经济带要素耦合研究，基于双核视角的长江经济带空间布局研究，以及基于宜居视角的长江经济带人居环境研究。具体而言，长江经济带的发展，应立足流域经济本质，以三级流域为基本单元，通过社会经济类要素与资源环境类要素的综合集成分析和空间匹配耦合分析，提炼长江经济带的空间开发类型与特色，谋划经济社会和资源环境的协调发展。与此同时，应以“一带一路”战略为背景，理清长江经济带在全国发展的宏观战略地位；通过对外通道、对外门户及其与中心城市内在关系的分析，以双核结构模式为理论工具理清长江经济带的基础设施格局和城镇演化机理，细化三大城市群的演化过程与内在机理。在上述基础上进一步从环境宜居角度，理清长江经济带的人居环境类型并进行环境宜居性评价，为成为全国环境宜居的先导区和示范区提供相应的对策建议。

英文摘要：

China has been highlighting the planning and construction of the Yangtze River Economic Belt （YREB）, radically every ten years. This indicates the important strategic roles of the YREB in China, which has resulted in great academic achievements in studying the YREB. These achievements raise an academic question： what is the new perspective on studying the YREB in the new era？ This paper will systematically review the macro development trend at national and international levels and the general characteristics, issues and trends of the YREB. Based on the previously developed innovative theories and methods in the areas of regional development and the relevant studies on the YREB, this paper aims to propose three new perspectives on its future development. The first perspective of river basin is focused on coupling all the elements of the YREB. The second perspective of dual-nuclei concentrates on the spatial layout of the YREB. The third perspective of livability will look at the human settlement environment of the YREB. Specifically, the development of this region should be dependent on the economic strength of the river basin, using the three-level basin as a basic unit. Its socio-economy and resource and environment elements should be systematically integrated and coupled and spatially matched. Such analyses are used to refine the spatial development types and patterns, and particularly to achieve the coordination between socio-economic and resource and environment systems. Meanwhile, the macro strategic roles of the YREB in China should be explicitly positioned within the background of ＇One Belt One Road＇ national strategy. The internal relationships between the YREB and other central cities should be clearly analyzed through its external pathways and doors. The patterns of infrastructure and evolution of cities and towns within the YREB should be clarified using the theory of dual-nuclei structure. Furthermore, the evolution process and essential mechanisms of the three urban agglomerations can be
