The sector's total revenue amounted to 5.05 trillion yuan ($727 billion) in January-October, up 15.1 percent from a year earlier, the Ministry of Industry and Information Technology (MIIT) said.

Picking up pace for two straight months, the sector is in the fastest expansion this year. "It has maintained stable and sound development trend," the MIIT said.

Combined profits grew 12.1 percent year-on-year to reach 636.1 billion yuan. MIIT data also showed stable software export growth, and increases in both the number of employees and average salary levels.
