Although both the official and HSBC PMI surveys are seasonally adjusted, some analysts cautioned against reading too much into last month's data, given the possible impact from the long Lunar New Year holiday, which began on January 31 and covered early February. Many plants and offices shut for extended periods during the festival.
To smooth out seasonal distortions, the statistics bureau is scheduled to release combined January-February growth figures on factory output, fixed-asset investment and retail sales in March.
Despite signs of firmer global demand, a drive by Chinese regulators to rein in the shadow banking sector could hurt investment growth, while Beijing's continuing anti-corruption campaign could hurt consumption, analysts say.
On Monday, the statistics bureau will release the official services PMI at 0100 GMT, ahead of the final HSBC/Markit PMI due out at 0145 PMI.
China's annual economic growth slowed to 7.7 percent in the fourth quarter from 7.8 percent in the previous quarter, and economists expected growth to slow further to 7.6 percent in the first quarter of 2014.
In 2013, China's economy grew 7.7 percent, steady from the previous year and fractionally above market expectations of 7.6 percent, which would have been the slowest since 1999.
Premier Li Keqiang is widely expected to stick with the 7.5 percent economic target for 2014 at the annual parliament meeting due to open on March 5.
