The Conference Board's measure of CEO confidence rose one point to a reading of 64 in the fourth quarter -- readings of more than 50 indicate more positive than negative responses. In comparison, the figure was 24 one year ago.

"The continued improvement in CEO confidence suggests further economic growth in 2010," said Lynn Franco, director of The Conference Board consumer research center. "However, short-term expectations do not suggest a significant strengthening in the pace of growth."

Overall, 75% of CEOs surveyed said business conditions have improved compared with six months ago, and 58% said they expect conditions to improve in the next six months.

When asked about their own industries, 68% said business conditions have improved compared with six months ago, but only 45% said they expect improvement in the months ahead.
