China's economy grew by 8.1% in 2021 as industrial production rose steadily through the end of the year and offset a drop off in retail sales, according to official data from China's National Bureau of Statistics released Monday.

Fourth-quarter GDP rose by 4% from a year ago, according to the statistics bureau. That's faster than the 3.6% increase forecast by a Reuters poll. For the full year, China economists expected an average of 8.4% growth in 2021, according to financial data provider Wind Information.

Industrial production rose by 4.3% in December from a year ago, the bureau said, also beating Reuters' forecast of 3.6% growth. Notably, auto production grew for the first time since April, up by 3.4% year-on-year in December.

Fixed asset investment for 2021 grew by 4.9%, topping expectations for 4.8% growth. Investment in real estate rose by 4.4%, while that in infrastructure rose by 0.4%.
