【文/观察者网 柳白】"五角大楼与人工智能（AI）巨头的共同软肋：都极度依赖中国电池"——《纽约 时报》12月23日以此为题发文，再炒中美技术竞争话题。 这篇文章渲染说，中国在锂电池领域的绝对主导地位，已对美国人工智能产业和国防安全构成双重挑 战。美国自身面临产业补贴不足、环保成本高、技术积累薄弱等障碍，要摆脱对华依赖可能需耗时五年 以上，尤其是特朗普政府政策自相矛盾，一方面说要扶持电池产业，另一边却大肆打压电动汽车，而这 正是电池最大的需求来源。 "无论技术还是规模，中国遥遥领先" 这些数据中心不远处便是五角大楼，那里的军方官员也发出了类似的警告，只是原因不同。军事战略家 目睹乌克兰战场正在重塑现代战争，称美军将需要数百万块电池为无人机、激光武器及无数未来武器供 能。 作者认为，乌克兰战场正在重塑现代战争形态，硅谷则全力竞逐以维持其人工智能领先地位，而中国在 电池领域的主导优势引发的"恐慌"，早已超出汽车行业范畴。 在美国弗吉尼亚州北部的"数据中心走廊"，一座座如飞机库般宏伟的无窗建筑，正为美国的人工智能产 业提供动力支撑，该产业正陷入与中国的激烈竞争之中。 然而，这些数据中心却越来越依赖美国的地缘政治对手 ...

Core Viewpoint - The Chinese semiconductor equipment suppliers are poised for structural opportunities despite local semiconductor companies' stock prices reaching a four-year high, as demand for equipment will benefit from the ongoing industrial upgrade wave [1][6]. Group 1: Market Performance - The Shanghai Stock Exchange STAR 50 Index, focusing on local chip companies, surged 28% in August, reaching a historical high, driven by regulatory guidance to reduce reliance on Nvidia's H20 chips, catalyzing the domestic substitution process [1]. - The current price-to-earnings (P/E) ratio of the STAR 50 Index is 62 times, which is 50% higher than its five-year average, while the Philadelphia Semiconductor Index's P/E ratio stands at only 24 times [1]. Group 2: Investment Focus - Caution is advised regarding listed companies directly involved in chip production, as their valuations reflect expectations and face challenges related to demand sustainability and capacity targets [4]. - The stock price of Cambricon Technologies (688256.SH) doubled since December, with a P/E ratio exceeding 200 times, making it the most expensive stock in A-shares [4][5]. Group 3: Equipment Suppliers - The focus is on equipment suppliers, with Northern Huachuang Technology Group (002371.SZ) stock rising 30% this year, while the semiconductor equipment sector saw an 18% increase [5]. - The total investment by Chinese cloud service providers this year is approximately $50 billion, only one-sixth of the $330 billion investment by the top four U.S. hyperscalers, indicating significant room for capital expenditure growth [5]. Group 4: U.S.-China Technology Competition - There may be a "compromise" in U.S.-China technology competition, where China continues to purchase older Nvidia chips while advancing its semiconductor self-sufficiency goals, creating a dynamic balance that preserves market space for international equipment suppliers and drives technological iteration for local suppliers [6].

Group 1: Trump's Approval Ratings - Trump's approval rating has dropped to a historical low, with 43% of Americans satisfied and 53% dissatisfied, resulting in a net approval rating of -10% [1] - This represents a 3 percentage point decline from the previous day, marking the lowest net approval since April 29 [1] - Public dissatisfaction appears to be fueled by Trump's recent actions, reigniting discontent towards the White House [1] Group 2: Federal Reserve and Economic Policy - Federal Reserve Chairman Jerome Powell stated that current interest rates are sufficient to limit economic activity and that monetary policy should not be adjusted hastily until inflation shows a clearer downward trend [3] - The Federal Reserve has maintained the federal funds rate target range at 4.25% to 4.5% for the fourth consecutive time, with potential for two rate cuts this year [3] - Trump has publicly criticized Powell, calling for an investigation into his actions and suggesting that Powell should resign [3] Group 3: U.S.-China Relations - There are indications that China may invite Trump to a military parade in Beijing, signaling a potential thaw in U.S.-China relations [5] - The visit could provide an opportunity for both nations to seek cooperation, especially after years of trade and technology conflicts [5] - Successful outcomes from Trump's visit could lead to a more stable relationship, benefiting both countries economically [5][7] Group 4: Technology Competition - The U.S. continues to impose technology restrictions on China, particularly in critical areas like semiconductor manufacturing and artificial intelligence [7] - The ongoing technology competition will remain a central aspect of U.S.-China relations, with China needing to focus on overcoming key technological challenges [7] - The future of U.S.-China trade relations will involve finding a new balance between cooperation and competition [7]
