(Yicai) Sept. 2 -- Four of every five Chinese firms listed on the Shenzhen Stock Exchange that released first-half earnings results before the end of last month had made a profit in the period.

Of the 2,270 profitable companies, earnings grew at nearly half in the six months ended June 30, down from 51 percent a year earlier, their financial statements showed.

The 2,837 Shenzhen-listed companies that had disclosed first-half results had a total net profit of CNY480 billion (USD67.6 billion) after excluding non-recurring items, down 18.3 percent from a year earlier. Their combined revenues climbed 0.8 percent to over CNY9.88 trillion (USD1.39 trillion)

By industry, those from the advanced manufacturing sector had a total net profit of CNY62.1 billion (USD8.7 billion) on operating revenues of CNY866 billion. The figures jumped 17 percent and 8 percent, respectively, in the second quarter from the previous one, indicating a recovery trend.

In the green and low-carbon sectors, the profitability of listed companies grew for the second straight quarter after surging 30 percent in the second from the first and 62 percent in the first from the fourth last year.
