我国大城市交通建设正在以地面道路交通为重点逐步向大力发展轨道交通转换,然而轨道交通是属于投资规模大、技术含量高的现代化交通设施,因此实现其车辆和机电设备国产化有着重要意义。因为它既有利于较大幅度地降低工程造价、节省外汇和建设资金、减少运营管理成本,又有利于发展我国地铁与轻轨相关产业、振兴民族工业、防止“万国牌”技术装备出现,避免在今后运营过程中技术装备和备件长期依赖国外、便于维修保养,因此说具有十分
However, the rail transit belongs to the modern transportation facilities with large investment and high technical content, so it is of great significance to realize the localization of its vehicles and electromechanical equipment. Because it is not only conducive to a substantial reduction in project cost, save foreign exchange and construction funds, reduce operating costs, but also conducive to the development of China's subway and light rail-related industries, revitalize the national industry, to prevent “Wan Guo card” technology and equipment to avoid In the future, the technical equipment and spare parts in the operation process will depend on the foreign countries for the convenience of maintenance and repair. Therefore,
