Profits of China's industrial enterprises jumped 81.6 percent year on year for the first five months this year, China's National Bureau of Statistics (NBS) said Friday.

Profits of the industrial firms totaled 1.54 trillion yuan (226.82 billion U.S. dollars) from January to May, and revenues increased 38.2 percent to 25.35 trillion yuan, the NBS said in a statement.

The figures cover state-owned and private firms with annual turnover exceeding five million yuan, according the NBS.

State-owned industrial firms accounted for more than one third of the total profit, reaching 524.38 billion yuan, 118.9 percent higher than the same period last year.

Most of the 39 major industries registered profits growth, while the petroleum processing, coking and nuclear fuel processing sectors saw profits shrinking by 8.9 percent on average, according to the NBS.
