(Yicai Global) July 1 -- E-commerce titan Alibaba Group Holding's CNY3 trillion (USD441.7 billion) market cap was the largest among companies based on the Chinese mainland as of the end of June.

The Hangzhou-based tech giant bested rival Tencent Holdings, which came second after leading the way at the end of last year, according to data from stock information provider East Money. Alibaba's share price [NYSE:BABA] rose a total 24 percent over the first six months to USD169.45 from USD136.7.

The 500 biggest firms listed in China and doing business on the Chinese mainland had a combined market cap of CNY57.9 trillion over the same period, up 20.6 percent from the end of last year compared with a 19.5 percent rise in the Shanghai Composite Index, per figures from Choice.

Each of the top 10 had a market cap of over CNY1 trillion, nine of which achieved the feat a year earlier while newcomer Kweichow Moutai surpassed the milestone for the first time. The minimum threshold to rank among the top 500 has more than doubled from 2011 to CNY10.3 billion (USD1.5 billion).

Most of the top half mil are in the financial, industrial or information technology sectors -- making up 85, 83 and 72 of the companies. Another 47 are from non-daily consumption fields, such as the tourism and automobile industries, and 45 are in medicine.

Beijing is home to 99 of the companies, with a total 317 coming from the capital and other Chinese economic powerhouses Hong Kong, Shanghai, and Guangdong and Zhejiang provinces.
