China is to invest about 77 billion yuan ($11.7 billion) this year on the construction of civil aviation infrastructure, especially airports, according to the Civil Aviation Administration of China.
The agency said it will step up construction of important new airports, including those in Beijing, Chengdu, Qingdao, Xiamen and Dalian.
Eleven key infrastructure projects and 52 upgrades or expansion work on civil aviation facilities will be started this year, the administration said in a statement.
It said work on Beijing's second international airport, the largest construction project in Chinese civil aviation history, is progressing well.
China plans to build 66 new civil airports in the next five years, taking the number of such airports on the Chinese mainland from 206 to 272.
Demand has been rising for air travel, spurring the development of more airports.
The civil aviation administration said Chinese people made 440m trips by air last year and predicted that the figure could rise to 485m this year.
