核心技术被国外垄断,怎么办?信号系统投资成本高,怎么办?现场服务响应速度慢,怎么办?备品备件采购周期长,怎么办?近年来,随着我国城市轨道交通的快速发展,与之相关的关键设备和技术的国产化和自主化工作日益受到重视并引起广泛的关注。其中,车辆、信号和牵引系统被认为是城市轨道交通领域最关键、最难以实现国产化和自主化的三大技术。鉴于此,国家发改委曾在2010年发布的《关于进一步推进城市轨道交通装备制造业健康发展的若干意见》(发改产业(2010)2866号)中提出,坚持自主创新与技术引进相结合,加快城市轨道交通关
What should I do? How to deal with the slow response time of on-site service? How long to buy spare parts? In recent years, with the rapid development of urban rail transit in our country, and The related localization and autonomy of key equipment and technologies have received increasing attention and have drawn wide attention. Among them, the vehicle, signal and traction system is considered as the most critical in the field of urban rail transit, the most difficult to achieve localization and autonomy of the three major technologies. In view of this, National Development and Reform Commission had promulgated in 2010 “Several Opinions on Further Promoting the Healthy Development of Urban Rail Transit Equipment Manufacturing Industry” (Development and Reform Industry (2010) No. 2866), insisting on the combination of independent innovation and technology introduction, speeding up Urban rail transit
