China's high-speed economic growth and severe environmental problems have resulted in a poor Environmental Performance Index and have affected China's sustainable development and ecological welfare improvement. Therefore, exploring whether there is a certain relationship between the two and their influencing factors is an important way and a breakthrough to solve the problems regarding green economic progress and ecological welfare enhancement. To this end, by using the undesirable slack-based measure (SBM) model, this paper measures the ecological welfare performance and the green economic efficiency of 11 cities in Zhejiang Province, China, from 2000 to 2019. Through the methods of spatiotemporal evolution, coefficient of variation, coupling coordination degree, and the Tobit model, we found that: (1) The development trend of urban green economic efficiency and ecological welfare performance were both in a "U" shape that first fell and then rose; (2) The coupling coordination degree between green economic efficiency and ecological welfare performance showed a wave-like upward trend as a whole and most cities have entered a more advanced coupling coordination stage during the study period. The coefficient of variation revealed a downward trend; (3) The urbanization level, industrial structure, and government investment can promote the regional coordinated development, while the industrialization degree and the opening level had a negative impact on it; (4) The "Two Mountains" theory was beneficial to the improvement of regional urban green economic efficiency and ecological welfare performance and their coordinated development both in theory and practice. Finally, according to the findings, we offer relevant suggestions on making good use of the country's preferential policies and informatization means from the perspective of the regional coordinated development.
中国经济的高速增长与严峻的环境问题并存，导致环境绩效指数（EPI）较差，影响了中国的可持续发展和生态福利的改善。因此，探索两者之间是否存在一定的关系及其影响因素，是解决绿色经济进步和生态福利提升问题的重要途径和突破口。为此，本文利用非期望性 SBM 模型测算了 2000—2019 年中国浙江省 11 个城市的生态福利绩效和绿色经济效率，运用时空演变、变异系数、耦合协调度以及 Tobit 模型等方法，发现：（1）城市绿色经济效率和生态福利绩效的发展趋势均为先降后升的“U”型；（2）绿色经济效率与生态福利绩效的耦合协调度整体呈波浪式上升趋势，且大部分城市在研究期间已进入较高级别的耦合协调阶段，变异系数呈下降趋势；（3）城市化水平、产业结构和政府投入能够促进区域协调发展，而工业化程度和开放水平则对其产生负面影响；（4）“两山”理论在理论和实践上均有利于提高区域城市绿色经济效率和生态福利绩效及其协调发展。最后，从区域协调发展的角度出发，根据研究结果，提出了充分利用国家优惠政策和信息化手段的相关建议。
