首先,对我国城市轨道交通运营线路及里程进行统计,结果显示: 截至 2023 年12月31日,全国拥有轨道交通的城市有61个,运营总里程约11 034 km(若不含“智轨”系统,则有54个城市,运营总里程10 866 km)。然后,对我国城市轨道交通新增建设规划批复情况进行统计,结果显示: 2023年,国家发展和改革委批复5个城市的轨道交通建设规划或建设规划调整方案,新增运营线路长度最多的仍为地铁制式。最后,分析我国城市轨道交通行业技术发展特点,认为: 1) 高质量发展是城市轨道交通管理的主基调； 2) 优质工程及技术创新比往年有所增加; 3)城市轨道交通仍保持较快速度发展，行业更关注已开通线路的运营和维保。可以预期，绿色低碳建造技术、智慧高效管控技术将是今后行业发展的重点方向。

First, the authors conduct a statistical analysis of the operating lines and mileage of urban rail transit in China. The results show that, as of Dec. 31, 2023, there are 61 cities nationwide with urban rail transit, with a total operating mileage of approximately 11 034 km (when the "ART" system is not included, there are 54 cities with a total operating mileage of 10 866 km). Second, the authors conduct a statistical analysis of the approval status of new construction plans for urban rail transit in China. The results show that, in 2023, the National Development and Reform Commission of the People′s Republic of China approved the construction plans (or adjustment plans) of urban rail transit for five cities, with the increase in operating line length still primarily due to the operation of metro systems. Finally, the authors analyze the technological development characteristics of China′s urban rail transit industry and conclud that: (1) Highquality development is the primary focus of urban rail transit management; (2) There is an increase in premium projects and technological innovations compared to previous years; (3) Urban rail transit continues to develop at a rapid pace, with the industry placing a greater emphasis on the operation and maintenance of already opened lines. It can be expected that green and lowcarbon construction technology as well as intelligent and efficient control technology will be the key focus for future industry development.
