BEIJING — China's producer price index (PPI), which measures costs for goods at the factory gate, went down 1.3 percent year-on-year in October, the National Bureau of Statistics (NBS) said on Nov 9.

The figure eased from the 0.9-percent year-on-year increase registered in September due to a high comparison base in the same period last year, said Dong Lijuan, a senior statistician with the NBS.

On a monthly basis, China's PPI rose 0.2 percent in October. The coal mining and washing industry saw its PPI rise 3 percent month-on-month in October on rising coal storage demand in winter.

The PPI of oil and gas extraction industry went up 21 percent year-on-year, while that of the coal mining and washing industry went down 16.5 percent year-on-year.

The data on Nov 9 also showed that China's consumer price index, a main gauge of inflation, rose 2.1 percent year-on-year in October.
