BEIJING, Nov 30(Reuters) - China's factory activity shrank for an eighth month in November, an official survey showed on Sunday, suggesting the need for further stimulus to boost demand, as manufacturers struggle with lacklustre domestic demand.

The official purchasing managers' index (PMI) rose to 49.2 in November, versus 49.0 in October, remaining below the 50-mark separating growth from contraction. It was in line with a median forecast of 49.2 in a Reuters poll.
