With the rapid development of urbanization, problems such as the degradation of water ecological environment have emerged. How to improve the water ecological environment in the process of urbanization has become one of the urgent problems facing policy makers. This paper studies the coupling coordination relationship between new-type urbanization and water ecological environment, with the purpose of using insights gained from the study to help improve the quality of water ecological environment and promote sustainable development of water ecological environment. We take 11 cities in China's Jiangxi Province as the research object, and construct the coupling coordination evaluation indicator system of new-type urbanization and water ecological environment, then using the coupling coordination degree model to examine the state of coupling coordination between new-type urbanization and water ecological environment from 2009 to 2019. We further explore its driving factors employing random effect panel Tobit model. The results show that: (1) The level of new-type urbanization in Jiangxi Province shows a steady upward trend, and the water ecological environment level tends to rise steadily and slowly, although the comprehensive score of water ecological environment in most cities is lower than 0.1, indicating that the situation of water ecological environment is not optimal yet and there is room for improvement. (2) In 2009, 2014 and 2019, the coupling coordination development level between new-type urbanization and water ecological environment in Jiangxi Province showed an upward trend, from moderate maladjustment recession to mild maladjustment recession, and from low coupling coordination to moderate coupling coordination, although the overall coupling coordination degree was low. (3) The investment in scientific and technological innovation, degree of opening-up and government capacity are positively correlated with the coupling coordination degree, while economic development level, resource agglomeration ability, education level and industrialization level are negatively correlated with the coupling coordination degree. These results can provide insights to support new-type urbanization and water ecological environment in the future, and hold great significance for urban sustainable development.
随着城市化的快速发展，水生态环境恶化等问题也随之出现。如何在城市化进程中改善水生态环境，已成为决策者面临的紧迫问题之一。本文研究了新型城镇化与水生态环境的耦合协调关系，旨在通过研究获得的启示，帮助提高水生态环境质量，促进水生态环境的可持续发展。本文以中国江西省的 11 个城市为研究对象，构建了新型城镇化与水生态环境的耦合协调评价指标体系，然后利用耦合协调度模型，从 2009 年到 2019 年考察了新型城镇化与水生态环境的耦合协调状态。进一步利用随机效应面板 Tobit 模型探讨了其驱动因素。结果表明：（1）江西省新型城镇化水平呈稳步上升趋势，水生态环境水平呈稳步缓慢上升趋势，尽管大部分城市的水生态环境综合得分均低于 0.1，表明水生态环境状况仍不理想，有较大的提升空间。（2）2009 年、2014 年和 2019 年，江西省新型城镇化与水生态环境的耦合协调发展水平呈上升趋势，由中度失调衰退型转变为轻度失调衰退型，由低水平耦合协调转变为中水平耦合协调，虽然整体耦合协调度较低。（3）科技创新投入、对外开放度和政府能力与耦合协调度呈正相关，而经济发展水平、资源集聚能力、教育水平和工业化水平与耦合协调度呈负相关。这些结果可以为未来的新型城镇化和水生态环境提供支持，对城市可持续发展具有重要意义。
