According to data published by the United Nations Statistics Division, China accounted for 28.7 percent of global manufacturing output in 2019. That puts the country more than 10 percentage points ahead of the United States, which used to have the world’s largest manufacturing sector until China overtook it in 2010.
With total value added by the Chinese manufacturing sector amounting to almost $4 trillion in 2019, manufacturing accounted for nearly 30 percent of the country’s total economic output. The U.S. economy is much less reliant on manufacturing these days: in 2019, the manufacturing sector accounted for just over 11 percent of GDP.
