KYODO: Amid persistent yen weakness, Japan and U.S. finance ministers held talks.

Yandong Micro shares tumbled on Aug. 31, closing at 49.52 yuan, down 7.87%, with a market cap around 70.7 bln yuan. Market commentary pointed to a large 1H loss, falling product gross margins, heavy capex for 12‑inch lines and resulting depreciation and financing pressure, and intensified competition in mature 6‑inch/8‑inch wafer foundry segments weighing on contract prices. Yandong Micro said operations are normal but some projects remain in construction, with substantial prior fixed‑asset investment and profits materially affected by capacity ramp‑up. The company added that 12‑inch chips are a long‑term trend while 6‑inch and 8‑inch still have demand, and product choices will depend on market supply‑demand conditions.

舊金山聯儲數據顯示，截至二季度的過去四個季度，美國全要素生產率增長1.10%，低於一季度的1.61%；利用率調整後全要素生產率下降0.42%，其中二季度單季年化降幅達到2.19%。總量數據確實尚未顯示AI帶來的生產率躍升。美聯儲最新研究認爲，AI仍處於能力提升、資本開支和企業採用階段；使用範圍雖然擴大，但強度偏淺，任務層面的效率改善尚未通過流程重構轉化爲企業及宏觀產出。歷史上，通用技術投資與生產率兌現之間通常存在數年時滯。
