China's producer price index (PPI), which measures costs for goods at the factory gate, went down 2.7 percent year on year in April, the National Bureau of Statistics (NBS) said Saturday.

On a monthly basis, the PPI edged down 0.4 percent in April, the same as the previous month, according to the NBS data.

The NBS attributed the decline primarily to imported international factors, which led to rapid decreases in prices of some international bulk commodities and price drops in related domestic industries.

Meanwhile, as China strengthens and expands macro policies to accelerate the growth of high-tech industries, price improvement has been occurring steadily in some industries, the NBS said.

With the policies to promote consumption and equipment upgrades continuously unleashing effects, the year-on-year decline in prices in food manufacturing and the new energy passenger vehicles industry narrowed by 0.2 percentage points in April.

Driven by growing new quality productive forces and the deep integration of sci-tech innovation with industrial innovation, prices in aircraft manufacturing, micro special motor and component manufacturing, and service industry, rose by 1.3 percent, 1.2 percent and 1 percent year on year, respectively.

In the meantime, as China continues to promote trade diversification and expand markets, some export industries have gained price improvement.

In April, the year-on-year price declines in electronic device manufacturing and textile and clothing industries narrowed by 0.7 and 0.3 percentage points, respectively, and the prices in semiconductor equipment manufacturing and integrated circuit packaging and testing series, went up 1 percent and 2.7 percent year on year, respectively.

In the January-April period, the PPI fell by an average of 2.4 percent compared with the same period last year.
