在“双碳”目标背景下，本研究聚焦西藏地区，通过构建数字经济、生态环境与清洁能源三系统的耦合协调评价指标体系，基于2013~2023年面板数据，采用TOPSIS熵权法与耦合协调度模型进行实证分析。结果表明：（1）西藏三系统发展水平整体呈上升趋势，数字经济实现跨越增长，清洁能源持续优化，生态环境呈倒U型趋势；（2）三系统耦合协调度经历了三段式演进，系统间协同效应持续深化。

Against the backdrop of the “dual carbon” goals, this study focuses on the Xizang. By developing an integrated evaluation index system for the digital economy, ecological environment, and clean energy systems, we conduct an empirical analysis using panel data (2013–2023), employing the TOPSIS entropy weight method and a coupling coordination degree model. The results indicate: (1) The overall development level of the three systems demonstrates an upward trajectory, characterized by leapfrog development in the digital economy, continuous optimization of clean energy, and an inverted U-shaped curve in the ecological environment. (2) The coupling coordination degree of the three systems has undergone a three-stage evolutionary process, with synergistic effects progressively intensifying.
