Members of Bradford Chamber of Commerce have expressed "grave concerns" over plans to elect regional assemblies.
It says plans may not benefit business and could add extra red tape.
Mike Cartwright, policy executive for the Chamber, said: "Many members, both on council and in general membership, have expressed grave concerns over the alleged benefits that the new regional assemblies can bring.
"The White Paper is not clear enough on either how specific targets can be met or what role the business community can play in delivering it.
"It is too vague on many issues, including accountability and the overall cost-benefit analysis, and the additional tier of bureaucracy is, of course, a concern."
Mr Cartwight added: "We have not yet submitted our response to government on the plans for elected regional assemblies.
"The government has asked for particular comments on stakeholder involvement by the end of this month and we will convey our views to the British Chambers of Commerce, our national body, as well as to government.
"We have, though, debated the issue at Chamber council.
"We would agree with Leeds Chamber of Commerce that only real powers could make a difference to improving this region's economy and would add that, even if proposals included such powers, clear monitoring and accountability is necessary to avoid profligacy."
The government has laid out proposals for elected regional assemblies in its White Paper - Your Region, Your Choice.
The Leeds Chamber is urging the government to rethink its plans.
Mr Manselladded:
"Any elected regional assembly should be given real powers to make a difference and that does not appear to be the thrust of current proposals.
"We have forwarded our concerns as a matter of urgency and are urging the government, on behalf of all businesses in the region, to re-think its proposals."
