Kou Xiaowei, an official from China's General Administration of Press and Publication (GAPP), says domestically-created computer games accounted for more than 60% of the market share in 2005.
Kou made the remarks this week as he addressed the 2005 China Games Industry Annual Meeting.
Kou said that in 2005 the number of game developers in China had increased from 73 in 2004 to over 120, and 192 medium and large-scale games had been developed, an increase of 76% over the previous year.
The Chinese Academy of Social Sciences has also published the "2006 Culture Blue Book" this week, which estimates that China's online game market value will reach CNY8.34 billion in 2006, accounting for up to 20% of the world's total.
Statistics from China Internet Network Information Center (CNNIC) shows that half of the 53 million broadband users in China are game players.
