WASHINGTON, Feb 3 (Reuters) - U.S. job growth likely accelerated in January, with wages expected to have increased steadily, suggesting a strong start for the Trump administration as it seeks to boost the economy and employment.

Nonfarm payrolls probably increased by 175,000 jobs last month, in part as warm weather bolstered hiring in the construction sector, according to a Reuters survey of economists. That would be a pick-up from the 156,000 jobs created in December.

President Donald Trump vowed during last year's election campaign to deliver 4 percent annual gross domestic product growth, largely on the back of a plan to cut taxes, reduce regulations, increase infrastructure spending and renegotiate deals in the United States' favor.

Although details on the policy proposals remain sketchy, consumer and business confidence have surged in the wake of Trump's election victory last November.

But with the economy near full employment, some economists are skeptical of the 4 percent growth pledge. Annual GDP growth has not exceeded 2.6 percent since the 2007-08 recession.

"Time will tell if Trump can keep the economy's winning streak alive. It's not going to be easy to bring back those manufacturing jobs lost since the late '90s," said Chris Rupkey, chief economist at MUFG Union Bank in New York.

The Labor Department will publish its closely watched employment report on Friday at 08:30 a.m. (1330 GMT).

With the minimum wage taking effect in more than a dozen states in January, average hourly earnings are forecast to have risen by 0.3 percent after increasing 0.4 percent in December. However, the year-on-year gain in earnings is expected to fall to 2.8 percent from 2.9 percent in December as the jump in wages seen in January 2016 drops out of the picture.

Rising wages could pave the way for the Federal Reserve to raise interest rates this year. The unemployment rate is forecast unchanged at 4.7 percent.

"Solid job growth should help, in part, lead to lower unemployment and firming wage pressures, and justify the Fed hiking interest rates twice this year," said Sam Bullard, a senior economist at Wells Fargo Securities in Charlotte, North Carolina.

The Fed, which hiked rates in December, has forecast three rate increases this year. On Wednesday, the U.S. central bank kept its benchmark overnight interest rate unchanged in a range of 0.50 percent to 0.75 percent. It said it expected labor market conditions would strengthen "somewhat further."
