摘要

研究区53个长江流域城市，分为26个干流城市（MC）、13个支流城市（TC）和14个连接湖城市（LLC）。高质量经济发展与水资源承载力之间的关系及其影响因素尚未得到系统的研究。很少有研究将YRBC分为MC、TC和LLC进行比较分析。本研究采用critical - topsis方法和耦合协调度（CCD）模型来评价HED与WRCC之间的CCD。此外，利用固定效应Tobit模型确定了影响区域CCD的关键因素。研究发现：(1)CCD正朝着中间协调的方向升级。(2)中上游的CCD明显优于下游；冷热点格局由“中部冷、东部热”向“西部冷、中部热”转变。(3)区域集聚能力（RAC）、技术投入水平和经济发展水平分别是影响中小企业发展的关键因素；政府一般公共预算能力和RAC是影响TC和LLC发展的关键因素。这些结论为中下游城市、中下游城市和中下游城市的差异化改善策略提供了依据，为全球类似流域城市的可持续发展提供了有价值的见解。

Coordinating high-quality economic development and water resources carrying capacity in the Yangtze River Basin cities: Achieving sustainable development goals

Study region

53 Yangtze River Basin cities (YRBC), categorized into 26 mainstream cities (MC), 13 tributary cities (TC), and 14 linking lake cities (LLC).

Study focus

The relationship between high-quality economic development (HED) and water resources carrying capacity (WRCC), along with its key factors, has not been systematically studied. Few studies have differentiated YRBC into MC, TC, and LLC for comparative analysis. This study applies the CRITIC-TOPSIS method and the coupling coordination degree (CCD) model to evaluate the CCD between HED and WRCC. Additionally, the fixed effect Tobit model is used to identify the key factors influencing CCD across MC, TC, and LLC.

New hydrological insights for the region

The research found, (1) The CCD is being upgraded towards intermediate coordination. (2) The CCD in the middle and upper reaches is surpassing that of the lower reaches; the cold and hot spot pattern has shifted from "central cold, eastern hot" to "western cold, central hot". (3) The key positive factors for MC, TC, and LLC are regional aggregation capacity (RAC), technology investment level, and economic development level, respectively; the key negative factor for TC and LLC is government general public budget capacity and RAC. These conclusions provide a basis for the differentiated improvement strategies for MC, TC, and LLC, offering valuable insights for the sustainable development of cities in similar river basins globally.
