Rozelle's group at Stanford has consulted at the prefecture level with the CCP [0]. The PRC is de facto federal with a significant amount of leeway at the prefecture (state) level. In fact, a number of PRC policy initiatives are often done in coordination with research groups at Stanford University. The Guiding Cases [1] is another ministerial level initiative that Stanford has consulted on.
