* Profits rise 14.9 pct y/y in Nov
* Profits rose at slower pace due to weaker PPI - stats bureau
* Manufacturing profit growth slows in Jan-Nov (Adds analyst comment, context)
BEIJING, Dec 27 (Reuters) - Earnings at China's industrial firms grew at their slowest pace in seven months in November, as demand and producer price gains eased in further confirmation of ebbing growth in the world's second-largest economy.
The lower income underscores a delicate balancing act for authorities as they extend a campaign to reduce China's reliance on credit-intensive investment without imperilling the economy.
Profits in November rose 14.9 percent to 785.8 billion yuan ($120.05 billion), the National Bureau of Statistics (NBS) said on its website on Wednesday. It marked the slowest monthly growth rate since April's 14.0 percent.
Earnings were pressured in November by a slower pace of price rises compared to previous months, He Ping of the statistics bureau said in a statement along with the data release.
He noted that November's decline in producer price inflation to 5.8 percent from 6.9 percent in October was one of the biggest of the year.
"Previous price increases were concentrated in upstream industries like coal and steel. Inflation in those areas is slowing, and the transmission of higher prices to downstream industries hasn't been very strong, which hurts profit margins," said Ye Bingnan, an economist at BOC International in Beijing.
More than half of the increase in profits in Jan-Nov came from coal mining and washing, iron and steel smelting and processing, chemicals, and oil and natural gas extraction, the statistic bureau's He said.
While the industrial sector has enjoyed a year-long construction boom that has fuelled demand and prices for building materials in a boost to growth, a government-led battle to clean toxic air and a crackdown on financial risks have started to drag on China's economy.
Chinese steel makers in 28 cities have been ordered to curb output between mid-November and mid-March. A campaign to promote clean energy by converting coal to natural gas has also hampered manufacturing activity in northern cities due to insufficient supply and high prices.
Chinese iron ore and coke futures stretched losses on Tuesday as steel prices fell further, weighed down by seasonal weakness in demand in the world's top producer during winter.
For the first eleven months of the year, profits reached 6.875 trillion yuan, up 21.9 percent from the same period and lower than the 23.3 percent annual growth in the January-October period.
