The bank's purchasing managers' index (PMI) stood at 50.4 this month, compared with 49.5 in October. Anything above 50 points to growth and anything below indicates contraction. It is the first reading above 50 since October 2011 and adds to a slew of upbeat trade, investment and sales figures released this month and last that have fuelled optimism.
"This confirms that the economic recovery continues to gain momentum towards the year end," Qu Hongbin, HSBC's chief economist for China, said in the bank's release.
