        长江上游地区分别占据长江经济带面积、人口和国内生产总值（GDP）的55.4%、33.2%和23.3%，上游地区高质量发展的程度关乎长江经济带相关国家战略目标的成败。文章通过上游地区在维系长江生命线、保障战略资源供给、筑守生态基底、强化空间联系、拓宽内陆市场等方面的角色分析，总结了其面临的传统路径依赖、城市结构极化、区域经济断陷、绿色资本转换低的突出挑战。比较了长江上游地区经济发展质量与中下游地区的落差。针对长江上游地区高质量发展情势，提出了从功能到治理，建立新时代国土空间多元适应体系；从中心到边缘，缩小城镇体系首尾级差的剧烈分化；从区域到县域，填充成渝经济圈西南向生产力塌陷；从平原到山区，锻造生态成色分区分级的经济门类；从主干到支流，铺设经济带高质发展的支干协同道路等战略思路，进而推进长江上游地区高质量发展的目标。

        The upstream region accounts for 55.4%, 33.2%, and 23.3% of the area, population, and GDP of the Yangtze River Economic Belt respectively. The level of high-quality development of the upstream region is closely associated with the success or failure of the national strategic objectives of the Yangtze River Economic Belt. Through analyzing the important role of the upstream area in maintaining the lifeline of the Yangtze River, ensuring the supply of strategic resources, maintaining the ecological base, strengthening spatial connections, and expanding the consumer market, authors summarize the tough challenges faced by the upstream region, such as traditional path dependence, polarization of urban structure, regional disparity, low green-capital conversion, and inadequate development quality. In the process of promoting the goal of high-quality development in the upstream region, we argue that it is an important strategy to build a multi-scale adaptation system for land space, to narrow the sharp differentiation between the first and the last grades of urban system, to fill in the depression on the edge of Chengdu-Chongqing Economic Circle, to clarify the economic categories based on ecological capital, and to bridge an cooperation mechanism between mainstream and tributaries for highquality development.
