Huatai Securities predicts that millions of newborns will boost relative consumption with an increase of 120-160 billion yuan ($19-25 billion) a year. As a result, stocks of the companies in the fields such as food and beverage manufacturing, toys, children's clothing, and the education and training industry will likely surge.

"Dairy and baby-related stocks are all benefiting, and I expect real estate, education and healthcare to also get some support," said Zhang Yanbing, an analyst at Zheshang Securities in Shanghai.

The predictions have been proved in the short term on Friday, as food and beverage shares gained despite a 0.1 percent dip of the Shanghai Composite Index.

Among Friday' most active stocks in Shanghai were Citic, up 3.7 percent to 15.86 yuan and dairy company Yili Group, up 2.4 percent to 15.93 yuan.

In the morning session, Beingmate, a Shenzhen-listed manufacturer of baby foods, was up 10 percent, hitting the daily limit set by Chinese regulators for stock gains.
