But according to the report, more than a third of the 82 council leaders and chief executives that responded to a survey carried out as part of the study think that there are no local services that could not be delivered by a third party - whether a private or a voluntary sector provider.
The report found that more than two-thirds of council bosses believe that a benefit of commissioning or working with private or voluntary organisations to deliver services is "making use of external expertise". More than half said that outsourcing could help deliver more innovative services, while 45.3 per cent said that it could make services more efficient, according to the report.
It urges councils to "give up some of their control and to embrace working with providers of all types to design innovative and efficient services".
The report adds: "We encourage the private sector to be more responsible, not just looking for quick profits by restructuring back office functions, but developing more long-term, mature and strategic partnerships that share both risk and reward with councils."
Cabinet Office minister Oliver Letwin described the report as "an enormously useful contribution to the debate".
He said: "We absolutely have to find the means of allowing things to be done at a much more local level than they have been done before and within each locality find the means to allow things to be done by a much wider range of diverse providers."
