The current model for devolution is unsustainable according to the first minister.
Members of the Scrutiny of the First Minister Committee were questioning Carwyn Jones AM on the government's legislative programme on 14 November 2012.
This was the committee's first opportunity to scrutinise his work since the assembly was given law making powers in the March 2011 referendum.
"It is not sustainable in the long term," said Mr Jones of the current settlement.
"The reserved power model is much, much clearer.
"It is in the interest of Wales and the UK to have clarity.
"At the end of day, clarity means both administrations able to carry on in a far more coherent way."
To date the government has introduced bills on local government byelaws, school standards and organisation, public audit and a mandatory food hygiene rating scheme.
Mr Jones responded to further questioning on how legislation is introduced, the process of scrutiny, the relationship between the Welsh and UK governments and questions relating to enterprise and business.
