Revenue in China's software industry rose by 29.1 percent year on year to 604.8 billion yuan (about 89.34 billion U.S. dollars) in the first half of 2010, the Ministry of Industry and Information Technology (MIIT) said Monday.

The speed of the growth was 6.4 percentage points higher than the same period last year, said a statement on the MIIT website.

Further, export volume of software grew by 22.7 percent to 10.33 billion U.S. dollars in the first six months, but the speed of the growth was 6.4 percentage points lower than the average level of the industry, the statement said.

Furthermore, outsourcing services provided by the country's software industry rose by 38.8 percent to 1.23 billion U.S. dollars, though the growth speed was 25.7 percentage points lower than the previous year.

However, experts note that the development of China's software industry remains unbalanced. The eastern regions finished 529.3 billion yuan of software business revenue, about 87.5 percent of the country's total business volume.
