中国9月制造业PMI升至50.1% 结束两月收缩小型企业需求仍显不足

中国9月制造业采购经理指数（PMI）升至50.1%，环比上升0.3个百分点，重新进入扩张区间，结束此前连续两个月的收缩态势12。这一改善被视为中国经济的积极信号2。

从企业规模看，大型企业表现相对稳健，其PMI为50.6%，但中型企业PMI为49.7%，小型企业PMI仅为48.9%1。其中小型企业的订单类指数处于荣枯线以下，反映出需求不足问题较为突出1。生产方面，9月生产指数为51.7%，比上月上升1.3个百分点；新订单指数为50.5%，虽仍在扩张区间但环比下降0.1个百分点1。从业人员指数则为48.4%，比上月下降0.3个百分点1。

在调查的21个行业中，有12个行业PMI高于临界点，比上月增加4个1。分析师指出，应加大宏观政策逆周期调节力度，扩大需求并增加企业订单1。

China's manufacturing sector returned to expansion in September, with the Purchasing Managers' Index (PMI) rising to 50.1%, marking a 0.3 percentage point increase from August 1. This improvement ended a two-month contractionary streak, signaling renewed economic momentum 2. However, the expansion masked significant divergences across enterprise sizes, revealing persistent challenges in demand generation.

The breakdown by firm scale exposed uneven recovery patterns 1. Large enterprises posted a PMI of 50.6%, while medium-sized firms recorded 49.7%, and small enterprises lagged significantly at 48.9% 1. Small businesses faced particular headwinds, with their order-related indices remaining below the 50-point contraction threshold, reflecting inadequate demand 1. The production index improved to 51.7%, up 1.3 percentage points month-on-month 1, while the new orders index stood at 50.5% 1. Employment pressures also mounted, as the employment index fell to 48.4%, declining 0.3 percentage points 1. Among the 21 surveyed industries, 12 registered PMI readings above the 50-point critical level, an increase of four industries compared to August 1.
