Urban economic development is crucial to regional economy and people's life, and enhancing the efficiency of urban economic development is of great significance to boost sustainable and healthy economic and social development. In this paper, from the perspective of sustainable development, data of 104 cities in China's Yangtze River Economic Belt (YREB) from 2004 to 2019 are selected, and the urban resource consumption index and urban pollutant emission index are synthesized as new input-output indicators using the Time Series Global Principal Component Analysis (GPCA), combined with the Global Malmquist-Luenberger (GML) Index Model, Standard Deviation Ellipse (SDE) Model to measure the total factor productivity index of urban economic development in China's YREB and analyze its spatial and temporal evolution. The results show that from 2004 to 2019, the total factor productivity index of urban economic development in China's YREB showed an overall fluctuating upward trend with an average annual growth of 5.8%, and the analysis by decomposing indicators shows that the growth of total factor productivity of urban economic development in China's YREB is mainly influenced by the growth of technological progress. Meanwhile, there are obvious regional differences in the efficiency of urban economic development in China's YREB, with the largest difference in the middle reaches of the Yangtze River, the second largest in the upper reaches, and the smallest in the lower reaches. From 2004 to 2019, the efficiency center of gravity of urban economic development efficiency in the YREB has always been located in the middle reaches of the Yangtze River region. The spatial distribution pattern of urban economic development efficiency in the YREB is dominated by the northeast-southwest direction and tends to be concentrated in the study time period.
城市经济发展对区域经济和人民生活至关重要，提高城市经济发展效率对于促进可持续健康的经济社会发展具有重要意义。本文从可持续发展的角度出发，选取中国长江经济带（YREB）的 104 个城市 2004-2019 年的数据，利用时间序列全局主成分分析（GPCA）将城市资源消耗指数和城市污染物排放指数综合为新的投入产出指标，结合全局 Malmquist-Luenberger（GML）指数模型、标准差椭圆（SDE）模型测算了中国长江经济带城市经济发展的全要素生产率指数，并分析其时空演变。结果表明，2004-2019 年，中国长江经济带城市经济发展全要素生产率指数整体呈波动上升趋势，年均增长率为 5.8%，指标分解分析表明，中国长江经济带城市经济发展全要素生产率的增长主要受技术进步的增长影响。同时，中国长江经济带城市经济发展效率存在明显的区域差异，其中中游地区差异最大，上游地区次之，下游地区最小。2004-2019 年，长江经济带城市经济发展效率重心一直位于长江中游地区。长江经济带城市经济发展效率的空间分布格局以东北-西南方向为主，在研究时间段内趋于集中。
