英媒:中国如何使电动汽车成为主流
Huan Qiu Wang Zi Xun· 2025-06-23 21:51
本世纪初,中国制定了主导未来科技的计划。这个曾是自行车大国的国家,如今已成为全球电动汽车领 域的领军者。汽车行业分析师迈克尔·邓恩表示:"在电动汽车领域,中国领先10年,且实力远超其他国 家。" 中国取得如此大的领先优势,得益于其能长期动员经济资源推进战略目标的实现。美国战略与国际问题 研究中心(CSIS)估计,自2009年至2023年底,中国在电动汽车领域投入达2310亿美元。从消费者、 汽车制造商到电池供应商等,涉及中国电动汽车行业的各个环节都有资格获得资金和支持。例如,比亚 迪被鼓励从生产智能手机电池转向专注于生产电动汽车;创立于2011年的宁德时代,如今已供应全球 1/3的电动汽车电池。迈克尔·邓恩说:"如今,若你想制造一块用于电动汽车的电池,所有路径都会指向 中国。" 中国还建设了全球最大的公共充电网络,充电站集中在大城市,司机距离最近的充电站仅几分钟路程。 此外,CSIS的研究显示,中国政府资金的投入也让电动汽车在经济上更具吸引力。公众在将非电动汽 车置换为电动汽车时可获得补贴,还能享受免税政策和公共充电站的优惠电价。 虽然目前一些西方国家对中国制造的智能电动汽车及相关设备实施限制或禁令,但对于中 ...
