The key infrastructure sectors had recorded growth of 7.8 per cent in the same month last year.
However, the eight core sector industries had registered an eight-month high growth of 6.6 per cent in October 2012. In July, the sectors grew by 1.2 per cent.
The cumulative expansion of these industries in April - November 2012 slowed to 3.5 per cent from 4.8 per cent in the same period last year, according to official data released today.
The eight industries include crude oil,petroleum refinery products, coal, electricity, cement and finished steel and have a weight of 37.9 per cent in the overall Index of Industrial Production (IIP).
"The decline in growth in November, 2012 was on account of negative growth witnessed in the production of coal, natural gas and cement and deceleration in growth rates of electricity, steel and petroleum refinery products," it said.
Economists said poor performance of core industries points towards economic slowdown. These numbers will have implications on industrial production data for November to be released later next month.
"The number clearly indicating continued slowdown in the economy. There is an urgent need to boost investments in the country. It will have its effect on IIP as well," Ficci's former secretary general Rajiv Kumar said.
Belying expectations of recovery, economic growth slipped further in the July-September quarter to 5.3 per cent, raising fears that the slowdown may pull down the annual growth rate to decade's low level. MORE
