BEIJING, Jan. 17 -- China's industrial production sustained its development in 2022, with the high-tech manufacturing and equipment manufacturing sectors posting robust performance, official data showed Tuesday.

The value-added industrial output, an important economic indicator, went up 3.6 percent year on year in 2022, data from the National Bureau of Statistics (NBS) showed.

The country's industrial sector continued to serve as the "ballast stone" of its economy, said Kang Yi, head of the NBS, at a press conference.

The contribution rate of the industrial sector to economic growth has reached 36 percent, Kang said.

He added that China's total value-added industrial production hit 40.2 trillion yuan (about 6 trillion U.S. dollars), while the manufacturing sector's output reached 33.5 trillion yuan, both ranking first globally.

A breakdown of the figure by industries showed the mining industry's output increased by 7.3 percent last year, while that of the manufacturing sector rose by 3 percent.

Specifically, the high-tech manufacturing and equipment manufacturing sectors posted strong growth momentum, with their output values jumping 7.4 percent and 5.6 percent, respectively, both higher than the overall industrial output growth.

By ownership, state-controlled enterprises saw a 3.3 percent increase in output in 2022, while the private sector's output grew 2.9 percent.

In terms of product types, new-energy vehicle output logged the most notable increase of 97.5 percent year on year in 2022.

The industrial output measures the activity of large enterprises each with an annual main business turnover of at least 20 million yuan.

In December alone, the industrial output grew 1.3 percent from a year earlier and 0.06 percent from November, the NBS said.
