Bubb made the call at the group's summer forum in London last week, saying that the sector needs a step-change in state intervention, from small short-term grants for pilot projects, to long-term support at national, regional and community level.
Bubb held up the success of IdeA, which receives £27m a year from central government to improve performance in local government, as a model for the proposed think-tank. He said: "It is entirely appropriate that we should look to central government for support. I believe we should look to the Home Office, and especially the Active Communities Directorate."
The directorate has set aside up to £80m to provide support for infrastructure and capacity building in the sector. Bubb said "signs are good" that the Home Office will provide a blueprint for supporting the sector.
