The companies include Didi Chuxing, Xiaomi, Alibaba Cloud, Cainiao and electric car battery producer Contemporary Amperx Technology.

Among the Chinese tech giants, Alibaba invested in most unicorns last year, creating a total of 29 unicorns, followed by Tencent, Xiaomi and Baidu.

More than 80 percent of the unicorns are located in Beijing, Shanghai, Hangzhou in East China's Zhejiang Province and Shenzhen in South China's Guangdong Province, according to the report.

Unicorns have become the representatives of new industries, business models and growth momentum in recent years. 

And the China Securities Regulatory Commission's favorable IPO policy for unicorns in four sectors - internet, artificial intelligence, environmental protection and bio-technology - shows the country's focus on unicorns' contribution to domestic economic growth.

China Securities Regulatory Commission spokesperson Gao Li said at a regular press briefing on Friday that the commission is researching the possibility of unicorns getting listed in the domestic A-share market.

Unicorns are private companies that are registered in the Chinese mainland within 10 years, with a value surpassing $1 billion.
