Based on the related environmental data of Chengdu and Chongqing from 2011 to 2020, this paper constructs a multivariate environment performance evaluation system, combines the self-built indicator system determination criteria and rules, evaluates and compares the environmental performance of Chengdu and Chongqing, and also discusses the impact of COVID-19 on urban environmental performance. The research results show that the overall environmental performance increased from 2011 to 2020, but there are differences between different subsystems, mainly manifested in the best water environment performance, followed by air environment and solid waste; moreover, the noise environment maintains a relatively stable level. By comparing the average levels of various subsystems of the Chengdu-Chongqing dual cities from 2011 to 2020, it can be seen that Chengdu City has better environmental performance in air environment and solid waste, while Chongqing City has better environmental performance in the water environment and noise environment. In addition, this paper also found that the impact of the epidemic on urban environmental performance mainly comes from the impact on the air environment. At present, the overall environmental performance of the two places has shown a trend of environmentally coordinated development. In the future, Chengdu and Chongqing should further optimize and improve their relatively weak environmental subsystems, deepen the joint action mechanism between the two places, and build a green and high-quality development economic circle for the Chengdu-Chongqing twin cities.
基于 2011 年至 2020 年成都和重庆的相关环境数据，本文构建了一个多变量环境绩效评价体系，结合自建指标体系确定标准和规则，对成都和重庆的环境绩效进行了评价和比较，并探讨了 COVID-19 对城市环境绩效的影响。研究结果表明，整体环境绩效从 2011 年到 2020 年有所提高，但不同子系统之间存在差异，主要表现在最佳水环境绩效，其次是空气环境和固体废物；此外，噪声环境保持相对稳定的水平。通过比较 2011 年至 2020 年成渝双城各类子系统的平均水平，可以看出，成都市在空气环境和固体废物方面的环境绩效较好，而重庆市在水环境和噪声环境方面的环境绩效较好。此外，本文还发现，疫情对城市环境绩效的影响主要来自对空气环境的影响。目前，两地整体环境绩效呈现出环境协调发展的趋势。未来，成都和重庆应进一步优化和完善相对薄弱的环境子系统，深化两地联合行动机制，共建成渝双城绿色高质量发展经济圈。
