The power, metallurgical, transportation, automotive and foreign trade sectors rose by more than 67 percent, contributing 59.7 percent to the increased profits of the 28 sectors surveyed by the commission.

Sales revenues of the 417 enterprises hit 6.9 trillion yuan in the first seven months, up 20.5 percent from the same period last year.

Meanwhile, their exports reached 343.6 billion yuan, up 17.9 percent, which was 10.9 percentage points lower than the rise in the same period of last year.

With restrictions on exports of natural resources, the oil and petrochemical sector saw its exports drop 28.3 percent, while exports in the coal sector declined 15 percent.
