BEIJING, May 11 (Xinhua) -- China's producer price index (PPI), which measures costs for goods at the factory gate, went up 2.8 percent year on year in April, the National Bureau of Statistics said Monday.
On a month-on-month basis, PPI rose 1.7 percent in April, up from 1 percent in March.
NBS statistician Dong Lijuan attributed the rise in PPI to three main factors: rising prices in domestic petroleum-related sectors driven by international price movements, increased demand in certain domestic industries, and the continued improvement in market competition order, which led to price increases or smaller declines in relevant sectors. ■
