NEW YORK – A new study shows that funding for business startups declined in 2012, the first time that's happened in three years, as venture capitalists spent less money on fewer deals.

Capital-intense sectors like clean technology and life sciences were among the hardest hit, according to the MoneyTree study released Friday. It was conducted by PriceWaterHouseCoopers and the National Venture Capital Association, based on data from Thomson Reuters.

In all of 2012 startup investments fell 10 percent to $26.52 billion from $29.46 billion. There were 3,698 deals completed, down 6 percent from 3,937 in 2011. Venture investments also declined 13 percent in the final quarter of the year, to $6.4 billion from $7.38 billion a year earlier, though the number of deals was the same in both quarters at 968.
