Sinn Féin's housing spokesperson Eoin Ó Broin has said that multinationals creating jobs here would have "nothing to fear" from a government led by his party.
He was discussing Sinn Féin's attitudes towards taxation and fiscal policies amid government formation talks.
Speaking on The Pat Kenny Show this morning, he reiterated comments from party leader Mary Lou McDonald who said that they would be "intensifying" their discussions to form a government this week.
He said the election showed voters that for the first time in a long time, they had "a very clear choice".
Mr Ó Broin went on to say that Fianna Fáil need to clarify their position on a future coalition to form the next government.
He said: "If we put together an alliance for change, are they [Fianna Fáil] going to block it, are they going to undermine it?
"Fianna Fáil really need to clarify where they are, are they for change or are they for the status quo in government with Fine Gael."
In the election, people could choose a "conservative package" of Fine Gael or Fianna Fáil or "go for something different", he said, with this applying to fiscal spending too.
He said: "Parties have a responsibility to say if they were in government what would they do on tax and on spending, I don't think that's auction politics, I think that's just being honest with people.
"What we were saying is if we want to fix those big issues, the housing crisis, the health crisis, bring down the cost of childcare, then we need a greater level of revenue and a great level of investment.
"And I think that resonated with people. I think the broad mood of the electorate was for change."

Questioned on whether Sinn Féin "frightens the corporate horses", Mr Ó Broin admitted that there are some investors who are nervous of the party's policies.
However, he said: "Multinationals who are here to create jobs and to invest and produce have nothing to fear from Sinn Féin, in fact, our policies are better than Fianna Fáil and Fine Gael.
"But yes, some of the big institutional investors, some of the vulture funds, have they cause to be nervous?
"Yes, because we're on the side of renters and not institutional investors, and we'll freeze and reduce rents and end the tax giveaway for these huge investors.
"Because they're not doing anything good for our housing situation or our cities or society."
