National Bureau of Statistics: In May, the Manufacturing Purchasing Managers' Index (PMI) was 50.0%

The Manufacturing PMI in May settled exactly at the 50.0% boom-bust line—a figure that feels like a dangling question mark. Does this mean the momentum of economic recovery is stalling, pausing, or confronting a fresh stress test? Examining the sub-indices and performance across different company sizes, the answer points toward the third scenario. The marginal drop in the overall PMI conceals stark structural differentiation: the "temperature gap" between large firms and SMEs is widening, and demand-side softness is clearer than in the previous month.

The PMI for large enterprises defied expectations, climbing to 51.1%, up a significant 0.9 percentage points from April. This reflects their greater resilience and proactive edge in the recovery process, likely bolstered by resource advantages, policy support, and market positioning—possibly benefiting from infrastructure investment, rebounds in export orders for certain sectors, or consolidation of their core roles in supply chains.

However, the PMI for medium-sized enterprises plummeted by 1.9 percentage points to 48.6%, and that for small enterprises fell 1.6 points to 48.5%, both firmly in contraction territory. If this "large-strong, small-weak" pattern persists, it will not only drag down overall recovery momentum but may also exacerbate imbalances across the supply chain. SMEs are the main drivers of employment and innovation; their sustained sluggishness could significantly dampen consumption and private investment.

Among the five sub-indices, only the production index remained above the threshold, indicating that manufacturing capacity is still actively expanding. Yet this contrasts sharply with the new orders, raw material inventories, employment, and supplier delivery time indices—all of which fell below the critical mark. The divergence between "hot production" and "cold demand" is particularly striking. Insufficient new orders suggest enterprises may have the capacity to produce but lack the sales to match, potentially forcing them into a phase of passive inventory accumulation—which could constrain the sustainability of future production. The employment index staying below the threshold reflects cautious expectations about future demand and weak hiring intentions, highlighting persistent pressure on job stability.

From a broader perspective, this PMI data paints a picture of "divergent recovery" coupled with "insufficient demand-driven momentum." The next challenge for macro policy may lie in how to more precisely and effectively extend warmth to SMEs while supporting large firms in stabilizing the fundamentals—boosting their intrinsic vitality. Policies targeting SMEs—such as financing support, tax and fee reductions, and market expansion—need strengthening to help them navigate cyclical fluctuations. At the same time, vigilance is needed against price and inventory risks stemming from the sustained gap between production and demand. Through a combination of stabilizing expectations, stimulating consumption, and expanding investment, efforts should focus on building a more solid and balanced foundation of market demand. The 50.0% threshold is not just a warning signal—it should also mark the starting point for intensified policy action and structural optimization.
