BEIJING, Jan. 14 -- A total of 645 listed companies have seen their profits increase in 2013, 61 percent of all the companies listed on Shanghai and Shenzhen stock exchanges, China Securities Journal reported Tuesday.

Among the companies, emerging industries such as electronics, media and computers caught investors' eyes. According to the journal, 16 out of 17 media companies posted profits, with seven growing by more than 50 percent, thanks to government policy and market opportunities from economic restructuring.

According to the report, traditional industries, by contrast, presented a less positive picture. Sectors including mechanical equipment, electrical equipment and chemical engineering posted over fivefold losses in the last year.

The paper cited analysts as saying that these traditional sectors need to restructure to reverse rising operating costs, shrinking domestic market and high financing cost.
