内容概况：随着国内轨道交通行业的快速发展，铁路营业里程不断增加，对先进、可靠的ATC车载设备 的需求也随之增长。2025年1-5月，中国列车自动控制系统(ATC)车载设备进口数量为150台，同比增长 32.74%；进口金额为666.37万元，同比下降73.78%。进口端"量增价跌"现象背后，是政策调整与技术替 代的双重驱动。2025年3月实施的《重大技术装备进口税收政策管理办法》优化了免税目录，部分促使 企业转向性价比更高的国产设备或免税清单内产品。同时，国内ATC技术突破显著，如CRSC的CTCS-3 级系统已实现自主化，削弱了对高价进口设备的依赖。同期，中国列车自动控制系统(ATC)车载设备出 口数量为3834台，同比下降88.33%；出口金额为3479.74万元，同比增长4.41%。出口端"量跌价升"则凸 显结构性升级。国内ATC行业已形成全产业链出海能力，如交控科技在泰国建厂实现本地化生产，规避 关税并贴近需求。技术输出模式从"产品出口"转向"技术授权+本地适配"，如自动驾驶解决方案落地西 班牙，提升利润空间。 二、行业发展历程 中国列车自动控制系统（ATC）行业发展主要经历了四个阶段。20世纪60年 ...
