BEIJING, July 9 (Xinhua) -- China's producer price index (PPI), which measures costs for goods at the factory gate, went up 4.1 percent year on year in June, the National Bureau of Statistics (NBS) said Thursday.

On a month-on-month basis, PPI dipped 0.3 percent last month, the NBS data showed.

Analyzing the monthly changes, NBS statistician Dong Lijuan said lower international crude oil prices drove down prices in related domestic industries, while seasonal factors led to divergent price trends in the broad energy sector. Meanwhile, faster industrial upgrading boosted demand and lifted prices in some sectors such as new materials and industrial robots.
