45 per cent of people are concerned if Sinn Fein gets into Government, foreign investment into Ireland will decline.
The Red C Poll also found just one in three voters believe the party can solve the housing crisis.
42 percent meanwhile believe Sinn Fein can do a better job of running the health service than the Government.
Michael Brennan, Political Editor with the Business Post, says concerns over the future of foreign direct investment is shaping up to be a serious issue:
"That's going to be a big issue for the next general election and one for Sinn Fein to address because you have 300,000 people employed by multinational companies here, and the top 10 largest multinationals alone are paying 57% of our total Corporation Tax last year. So they're a huge part of the economy and the public finances".
