Beijing, Shanghai and Shenzhen have been China's top three leading cities for mass entrepreneurship and innovation for two years in a row, according to a ranking released by big data company Youedata and National Business Daily.

The entrepreneurial conditions and climate are relatively mature in the three cities, the report said.

The index for mass entrepreneurship and innovation of 17 Chinese cities, in which China's first batch of 28 demonstration bases for mass entrepreneurship and innovation approved by the General Office of the State Council last year are located, was measured in the ranking.

It reviewed the mass entrepreneurship and innovation situation and trend in the 17 cities, taking four major factors: the environment, vitality, capability and effectiveness into evaluation.

Benefiting from the local government's support, talents and capital, Chengdu, capital city of Southwest China's Sichuan province, comes fourth in the ranking, followed by Guangzhou, capital of Guangdong province.

The mass entrepreneurship and innovation program has been in full swing in China since it was initiated by Premier Li Keqiang at the 2014 Summer Davos in Tianjin.

This year's National Mass Entrepreneurship and Innovation Week will run from Sep 15 to 21 in Beijing.

Let's take a look at China's top 10 cities best for mass entrepreneurship and innovation this year.
