这一瓶颈背后，是价格与补能的双重焦虑。A级车用户对价格很敏感，而满足A级车续航要求的电池 通常需要50度电以上，导致纯电车在8-15万这个主力价位很难和燃油车竞争。同时，作为家庭主力 车，用户对续航和补能便利性的要求远高于代步小车（A00级、A0级）。里程焦虑叠加节假日排队 充电的现实，劝退了大量务实的主流用户。 另一个值得注意的是，当前补能资源正加速向"有产"车主倾斜。2025年新增充电桩中私人桩占比高 达83.6%，远超公共充电桩43.4%的增速。这意味着，数以千万计没有固定车位的城市居民（尤其在 一二线城市），很长一段时间将继续面临"找桩难、排队久、费用高"的难题。 时至岁末年初，宁德时代的巧克力换电业务热闹非凡—— 一年建成1020座乘用车换电站——这是2025年最后一天，宁德时代巧克力换电业务交出的今年最重 要的"成绩单"。 再往前看两个月，2025年10月，宁德时代联合京东、广汽推出了"埃安UT super"，该产品整合了三 方优势：宁德时代的电池技术与换电生态、京东的用户洞察与汽车后市场资源、广汽的整车制造能 力。首发2周，该车就完成了2000台的交付。 一家电池龙头，在换电赛道全力投入，从建站 ...

中新社北京12月26日电 (记者 刘文文)随着西安至延安高铁(简称"西延高铁")26日开通运营，中国高铁营 业里程正式突破5万公里大关，迎来高铁发展史上的又一里程碑。 高铁也重构了发展的"普惠路径"。鲁东红进一步指出，高铁将偏远地区与全国大市场无缝连接，让大凉 山的樱桃、延安的红色资源等得以快速"出山入海"，激活了沉睡的乡土潜力。高铁不只是一条交通线， 更是输送发展机会、促进区域均衡、推动共同富裕的"快车道"。 年末时节，广湛高铁、包银高铁、西延高铁等多个高铁线路密集开通。贾若祥称，随着中国"八横八 纵"的高铁网加快完善，区域联动融合发展的"硬联通"更加快捷，国内经济循环也因此更加畅通。 "这既是中国基础设施建设的重大成就，也彰显了中国在重大科技创新领域取得重要进展。"贾若祥指 出，中国高铁技术日益成熟、持续迭代升级，已形成了适应北方严寒、南方潮湿、西北风沙及高原高寒 等复杂气候与地形的完备技术体系。 如今，从山区到平原、从内陆边疆到沿海都市，高铁穿梭不息，将中国广袤的疆土紧密连接。民众出行 也逐渐从"走得了"向"走得好"跨越。国铁集团数据显示，"十四五"期间，动车组列车累计发送旅客128 亿人次，较"十三五 ...

（来源：吴说） 吴说获悉，AllianceDAO 联合创始人 QwQiao 发文表示，普遍的观点认为，由于卡网络（如 Visa、 MasterCard 等）收取高达 3% 的费用，稳定币等新型支付通道有可能颠覆传统支付体系。实际上，卡网 络从中获取的费用比例非常小。消费者获得大部分奖励以鼓励继续使用信用卡，发卡银行通过客户获取 为网络带来用户，收单银行通过商户获取为网络带来商户，Visa/MasterCard 虽然仅获得少量分成，但 通过规模效应可以几乎零边际成本扩展网络，商户支付所有费用，因为它们在谈判中处于较弱位置。这 是商业史上见过的最强大的网络效应案例之一。 ...

英伟达并不缺少挑战者，但到目前为止，他们都很难称得上是 英伟达的对手，难以撼动其领导地位。不过，未来这一点未必 不会改变。 作者： 刘劲等 封图：图虫创意 算力是人工智能最重要的基础设施和发展引擎。AI算力的代表企业英伟达（NVIDIA）凭借性能先 进的产品和难以复制的生态，在AI训练及推理芯片领域建立起了近乎垄断的领导地位，成为地球上 价值最高的上市公司。截至2025年11月，英伟达的市值约为4.5万亿美元，2025年第三季度营收 的同比增长约为62%。 在大模型发展的初期和中期，训练算力是核心瓶颈，决定了模型的"高度"，是算力芯片的战略制 高点。因此，我们在此着重讨论训练。 英伟达在训练算力上有统治性的地位。这种优势来自两个方面：先进的技术和生态的垄断。 主流大模型的参数规模已达千亿、万亿级别，训练时要对海量数据进行大规模计算，单机算力早已 远远不够，必须依托大规模芯片集群完成训练；要令这复杂而成本高昂的训练易于展开、效率高、 稳定可靠，还需要一整套的软件系统和工具来作为连接训练工程师、算力芯片和模型的桥梁。 因此，我们大致可以将训练对算力芯片的要求拆解成单芯片性能（单卡性能）、互联能力和软件生 态三部分 ...
