AI热潮是否已演变为泡沫？这一问题正牵动全球投资者的神经，也影响全球主要股市尤其是科技股的表现。 近日，全球知名投资人、《超智能与未来》作者拉斯・特维德(Lars Tvede，下称拉斯)接受中新经纬专访时指出，AI行业正处在长周期的早期阶段，泡沫 终将到来，但绝不是现在。 拉斯是一位横跨金融、科技与未来研究领域的丹麦学者、连续创业者。2016年，他与人共同创立了风险投资基金"北欧之眼"(NordicEye)，该基金成为北欧 有史以来最赚钱的风险基金之一。 拉斯认为，对比美国历史上几次重大投资热潮来看，目前美国AI产业相关支出占GDP比例仍处于历史合理区间。 高盛在今年10月发布的报告中估算称，美国目前AI相关投资仍不到GDP的1%，而在过去的技术浪潮中（包括铁路扩张、20世纪20年代的电气化浪潮以及 90年代末的互联网时代），投资占GDP的比例通常为2%至5%。 在拉斯看来，更关键的是，AI与传统基础设施建设存在本质差异。铁路和公路建成后性能基本固定，而AI工厂在初始投入后，会因软件持续优化实现自 我迭代升级。 "这就像建造铁路后，它能自行延长寿命、提升效率，还能自主搭建配套设施。"拉斯说，AI这种自我改进能 ...

Key Data Tracking PMI - In October, the manufacturing PMI fell to 49.0%, lower than the consensus expectations of Bloomberg and Reuters (49.6%). Seasonally, it fell more significantly than usual. The absolute value of 49.0% is the lowest for the same period since 2013, and the PMI of large enterprises dropped to 49.9%, returning to the contraction range [18]. CPI - In October 2025, the year - on - year CPI was +0.2% and the month - on - month was +0.2%. The year - on - year PPI was - 2.1% and the month - on - month was +0.1%. The recovery of CPI and PPI was due to seasonal factors, low - base effects, and "anti - involution" [21]. Import and Export - In October 2025, China's exports were $305.35 billion, imports were $215.28 billion, and the trade surplus was $90.07 billion. The significant decline in export growth was due to the high - base effect of the previous year and being weaker than the seasonal level, with the overdraft effect of pre - export orders showing [23][24]. Industrial Added Value - In October, the year - on - year growth rate of industrial added value dropped to 4.9% and the service industry production index dropped to 4.6%. Both production data had year - on - year growth rates below 5% for the first time since September 2024. Production weakness was related to high bases and reduced export support, and the decline was consistent with PMI performance. Most product output growth rates declined, except for some like ethylene and integrated circuits [28]. Fixed - Asset Investment - From January to October, fixed - asset investment decreased 1.7% year - on - year, and in October, it is estimated to have declined 11.2% year - on - year, the second - lowest growth rate since February 2020. The decline was mainly due to weakening internal impetus, with both private and public investment growth rates falling. In terms of expenditure directions and major categories, most investment growth rates declined, except for equipment purchases [31]. Social Retail - In October, the year - on - year growth rate of total retail sales of consumer goods dropped to 2.9%, and that of retail sales above the designated size dropped to 1.6%. Consumption maintained positive growth under the high - base environment of the previous year, with a slight increase in the two - year compound growth rate compared to September. The growth rate of optional consumption declined further, and the contribution rate of categories related to the "trade - in" policy to retail sales growth turned negative for the first time since September last year. The early "Double 11" on some platforms boosted the growth rate of essential consumption [34]. Social Financing - In October, the new social financing was 0.8 trillion yuan, a year - on - year decrease of 0.6 trillion yuan. Government bonds and credit were the main drags. The year - on - year growth rate of social financing dropped to 8.5%, and the credit growth rate in the social financing caliber dropped to 6.3%. The M1 growth rate declined as expected, but non - bank deposits turned positive year - on - year. Government bond net financing is expected to be 1.2 trillion yuan lower year - on - year from November to December. After considering the hedging of 500 billion yuan in government bond quotas, it is still expected to drag down social financing by 0.2 percentage points. The new policy - based financial instruments were fully disbursed in October, and subsequent supporting financing is expected to improve, offsetting the decline in social financing to some extent [37].
