投资逻辑 手部边际变化未来变化的主要集中点，单台人形机器人所需微型丝杠数量有望达到 34-44 个。根据特斯拉公开信息， GEN3 灵巧手相比于 GEN2 的主要变化在于：（1）手部增加了自由度，从 11 提升到 22 个；（2）驱动器装载在了手腕部 位。若远指关节和近指关节耦合，则需要 17 个主动自由度，若不耦合则最多需要 22 个主动自由度；每个主动自由度 对应所需微型丝杠为 1 个。 手部承载力有待提升，丝杠是高承载力方案。当前灵巧手握力和承载力普遍低于 5KG，但据《2020 年中国成人健康调 查》，人手握力为 25KG 以上，支撑力可以达到自身体重的 60%-70%。机器人手若想全面实现通用性，则传动部件的承 载力亟待提升。其中承载力、传动效率和精度按排序看，丝杠综合能力高于腱绳和连杆，且滚柱丝杠>滚珠丝杠>梯形 丝杠，因此微型滚柱丝杠的具备较高的需求度，随着供应链的成熟提升性价比后，微型滚柱丝杠渗透率有望大幅提升。 当前成熟微型滚柱丝杠供应商较小，竞争格局较好。公开资料显示，目前上市公司中已经披露布局了手部微型丝杠业 务的包含浙江荣泰和五洲新春。其中浙江荣泰预备收购狄兹精密传动公司（KGG），该 ...

事件简介 4 月 4 日，因杜邦中国集团有限公司涉嫌违反《中华人民共和国反垄断法》，市场监管总局依法对杜邦中国集团有限公 司开展立案调查。 事件分析 杜邦的反垄断调查将成为行业的标志性事件，高端材料领域国产企业加速。近期的连续事件具有非常明显的行业标志 性，4 月 2 日美国宣布对所有贸易伙伴设立最低 10%的最低基准关税，对中国加征 34%的关税；4 月 4 日，国务院关税 税则委员会办公室宣布自 2025 年4 月 10 日对原产于美国的所有进口商品，在现行适用关税税率基础上加征 34%关税， 同时将 16 家美国实体列入出口管制管控名单，将 11 家美国企业列入不可靠实体清单等。在关税和反制关税发布的背 景下，杜邦的反垄断调查就更具有典型意义。我国是全球最大的化工产品市场，具有庞大的需求空间，伴随中国改革 开发，大批外资开始持续深耕中国市场，而近 20 年来，国内化工企业迅速崛起，已经能够形成大宗产品的充分自给， 并能够有效供给精细化工领域的中低端产品，较多海外企业难以维持有效的产品竞争力，转而在高端领域设立更多的 竞争壁垒，以维持竞争空间和利润空间。此次反垄断调查不仅仅标志，中国在化工高端材料的反制， ...

Industry Overview - Recent policies indicate a focus on supply-side reforms addressing "structural contradictions in key industries" rather than "overcapacity" issues[10] - The majority of industries in China face structural issues characterized by excess low-end capacity and insufficient high-end capacity[11] Capacity Utilization - As of Q4 2024, the industrial capacity utilization rate is at 65.9%, indicating that overcapacity is concentrated in specific industries[18] - Industries potentially facing overcapacity include non-metallic minerals, black metals, photovoltaic, lithium batteries, automotive manufacturing, petroleum and coal, specialized equipment, food manufacturing, pharmaceuticals, and chemicals[37] Types of Overcapacity - Overcapacity can be categorized into frictional, cyclical, and structural types, with structural overcapacity being the most persistent and challenging to resolve[3] - Structural overcapacity is characterized by the coexistence of low-end overcapacity and high-end capacity shortages, often requiring government intervention for resolution[38] Key Industries Affected - The steel and cement industries are experiencing both cyclical and structural overcapacity due to a downturn in the real estate sector, leading to a projected reduction in steel production by 30-50 million tons[41] - Emerging industries such as new energy vehicles, photovoltaics, and lithium batteries are facing frictional and structural overcapacity due to rapid technological advancements and local government competition[59] Policy Recommendations - The government aims to guide the orderly exit of inefficient capacity through supply-side reforms, focusing on both eliminating low-end capacity and expanding high-end supply[40] - Effective market mechanisms and government actions are necessary to address the "involution" competition in emerging industries, including the implementation of fair competition regulations[65] Risk Factors - Risks include the potential for slower-than-expected capacity elimination, a more severe downturn in the real estate market, and unexpected declines in exports[5]
