Among them, 763 are expected to make profits, while 484 will record year-on-year growth in net profit, accounting for 90 percent and 60 percent, respectively, said the journal.

Large enterprises dedicated to serving major national strategies have played an exemplary role and "little giant" companies in niche industries with cutting-edge technologies have shown strong momentum in the stock market.

Contemporary Amperex Technology Co Ltd, the world's largest electric vehicle battery maker, earned operating revenue of 328.59 billion yuan and net profit of 30.73 billion yuan in 2022, an increase of 152 percent and 93 percent year-on-year, respectively.
