But analysts say it could take quite some time before construction of planned railways, roads and other projects starts as local governments are burdened by piles of debt.

December factory output likely grew 7.4 percent from a year earlier, quickening slightly from 7.2 percent in November, when many polluting factories in north China were shut for a meeting of Asia-Pacific leaders in Beijing.

The PBOC is widely expected to cut interest rates further or lower reserve requirement ratios (RRR) for all banks, although some analysts believe it may be pausing on policy easing to wait for recent actions to take effect and lift growth.

UBS expects China's GDP growth to slow further to 6.8 percent in 2015, and rising deflationary pressure will spur the central bank to cut benchmark lending rates by at least 50 basis points this year.

Factory price deflation

Highlighting deflationary risks, producer prices may have fallen 3.1 percent in December from a year earlier. That would extend to 34 months a streak of declines that has eroded corporate earnings. November saw a 2.7 percent slide.

Annual consumer inflation likely hovered near five-year lows, at 1.5 percent, in December, leaving some room for the central bank to loosen policy if needed.

Reflecting lackluster domestic demand, China's imports may have declined 7.4 percent in December from a year earlier, following a 6.7 percent drop in November.

Export growth likely accelerated to 6.8 percent in December from 4.7 percent in November. The December trade surplus could be around $50 billion, near record highs.
