Though both measure manufacturing activity, each index offers slightly different perspectives and covers varying segments of the industry. With the latest figures due in the coming days, market watchers are poised to glean early insights into how Chinese industry is faring as the new year approaches. Here is a closer look at how these two indicators compare, and what their forthcoming releases might tell us.

What the PMIs Measure

A Purchasing Managers’ Index (PMI) reading provides a snapshot of the prevailing economic trends in the manufacturing sector. Any figure above 50 indicates expansion, while a number below 50 suggests contraction. Both the National Bureau of Statistics (NBS) and the Caixin surveys take into account new orders, production, employment, supplier delivery times, and inventory levels. These same underlying data points give a sense of the overall health of manufacturing operations and, by extension, a leading indicator of broader industrial and economic momentum.

Differences in Coverage and Methodology

While the NBS Manufacturing PMI (also referred to as the “official” PMI) and the Caixin Manufacturing PMI both monitor the pulse of Chinese manufacturing, they do so in different ways. The NBS survey largely focuses on larger, state-owned enterprises. Because these big players often enjoy closer government ties and better access to capital, their business outlook can sometimes offer a perspective on how major projects and government-led initiatives influence growth.

Meanwhile, the Caixin survey zeroes in on smaller and medium-sized firms, many of which are privately owned and more exposed to shifting market conditions. This difference in sampling means that the Caixin PMI often moves in ways that reflect changes in export demand, fluctuations in global orders, or shifts in consumer sentiment more quickly than the official index might reveal. Consequently, the Caixin index can sometimes act as an early indicator of turning points in the broader economy.

Recent Trends and Expectations

For the December round of data (to be released at the tail end of the month and in early January), analysts will be looking for further signs of stabilization in China’s manufacturing sector. The official NBS Manufacturing PMI is due to be announced on Tuesday, December 31, at 9:30 a.m. Shanghai time. The forecast figure is 50.5, up from the previous month’s reading of 50.3. If the forecast is accurate, this would mark a slight improvement and would be the second consecutive month above the key 50 threshold (indicative of expansion).

Two days later, on Thursday, January 2, at 9:45 a.m. Shanghai time, the Caixin Manufacturing PMI will be released. The forecast stands at 51.8, compared to the previous 51.5—a figure that, if realized, would likewise demonstrate ongoing expansion and potentially suggest a faster pace of growth than the official data set. Because the Caixin index tends to track smaller, privately owned businesses more responsive to real-time market conditions, its movements often pique the interest of traders, economists, and corporate strategists alike.

Reading the Signals

With both PMIs forecasting mild improvements, observers will be parsing the sub-indices closely. Even if the headline figures exceed 50, the details—such as growth in new export orders, changes in production costs, employment shifts, and purchasing activity—will be vital. For instance, if new orders continue to rise, that could indicate healthy domestic and foreign demand. Should employment levels remain under pressure, however, it might hint at ongoing caution among manufacturers.

Moreover, many will be watching how these PMIs stack up against the backdrop of global trade developments, currency fluctuations, and domestic policy measures. For much of the past year, trade tensions and a slowing global economy have weighed on China’s factories. Even so, pockets of resilience have emerged, particularly among higher-value manufacturing segments and companies that have managed to diversify their export markets.

Why These PMI Figures Matter

The performance of China’s manufacturing sector resonates far beyond the country’s borders. As the world’s second-largest economy, any sustained uptick in Chinese manufacturing could signal improved global demand for raw materials, components, and machinery. Conversely, a slump can sometimes foreshadow broader slowdowns, affecting commodity prices and corporate earnings around the world. This is why the upcoming releases on December 31 and January 2 will draw international attention from economists, investors, and policymakers.

Additionally, these PMI results will help shape expectations around China’s policy direction. If manufacturing momentum appears robust, it could reduce the impetus for further monetary or fiscal stimulus. Conversely, weaker-than-expected data might prod the government toward more proactive measures, such as targeted tax breaks, additional infrastructure spending, or a loosening of lending conditions to spur industrial activity and shore up employment.
