BEIJING, Oct. 15 (Xinhua) -- China's manufacturing sector saw 4.7 percent year-on-year growth in sales revenue during the first three quarters of 2025, accounting for 29.8 percent of total corporate sales revenue, official data showed on Wednesday.

This positive performance was driven by policy support measures such as tax and fee reductions, according to the State Taxation Administration (STA).

China is achieving continuous progress in making its manufacturing sector higher-end, smarter and more eco-friendly, thus providing significant support for economic growth, the STA said.

Specifically, the equipment manufacturing sector's sales revenue grew 9 percent year on year during this period -- comprising 46.9 percent of total manufacturing industry sales revenue.

Notably, sales revenues of key strategic sectors including aircraft, high-speed trains and deep-sea petroleum drilling equipment rose by 12.5 percent, 16.1 percent and 20.8 percent, respectively.

In the first three quarters of 2025, manufacturing enterprises boosted digital technology procurement by 10.6 percent year on year. Sustained high investment accelerated intelligent industry upgrades, particularly in smart equipment manufacturing, represented by robots and drones, which grew 23.6 percent year on year.

Energy-intensive manufacturing revenue share declined to 28.9 percent of total manufacturing sector revenue -- a decrease of 1.4 percentage points compared to the same period last year. Procurement of energy-saving and environmental protection services surged 34 percent year on year -- underscoring robust green governance investment momentum.

Tax authorities have continuously optimized services this year. From January to August, tax cuts, fee reductions and rebates for the manufacturing sector totaled 1.29 trillion yuan (about 182 billion U.S. dollars).

"Tax data demonstrates that China's tax and fee reduction policies have effectively lowered the burden on manufacturers, supported their production and operations, and promoted high-quality economic and social development," said Chen Binkai, vice president of the Central University of Finance and Economics.
