Growth in China's industrial production is likely to have slowed to a 13-year-low of 6 percent in November, China International Capital Corp. (CICC) said in a research note on Monday.

The slowdown reflects weak domestic and external demand, which led more companies to cut production, said the domestic investment bank.

Industrial output grew at an annual rate of 8.2 percent in October, the slowest in seven years and sharply down from 11.4 percent in September.

Data released on Monday showed the official purchasing managers' index of the manufacturing sector plunged to a record low of 38.8 in November from 44.6 in October, giving new signs the economy was further slowing.

The economy expanded 9 percent in the third quarter of the year, down from 10.4 percent in the first half and 11.9 percent last year.
