| With the emergence of local government governance innovations,it has become an important issue to promote the modernization of the national governance system and governance capacity by exploring the general rules of replicable and scalable policy innovations in the Chinese context and how to make those policy innovations with replicable and scalable policy innovations better diffuse so as to truly improve the actual effectiveness of government governance innovations.This paper takes the diffusion of local government governance innovations as the main research content,which has both theoretical value and practical significance.Through literature analysis,case comparison,in-depth interviews method,this study selects the “addressing public affairs once and for all”reform in Zhejiang Province as the object of research,uses the relevant theoretical tools such as diffusion theory of policy innovation,institutional change theory and inter-governmental relations theory,tries to analyze the diffusion mechanism of this policy innovation deeply.Further research has found that the policy attributes relying on innovation policy are the objects of the diffusion in the “addressing public affairs once and for all” reform,the policy attributes such as comparative advantages and high compatibility with existing policies are the bases for the diffusion.As the main body of innovation diffusion,government actors are the driving force and guarantee for the diffusion.The intensity of the vertical level of government and the frequency of horizontal interaction and communication have a profound impact on the diffusion of the policy innovation.Besides,external ecological factors also have an impact on the diffusion of this policy innovation.In the process of diffusion,problems such as serious homogeneity among policies,fierce political competition among governments,significant regional differences in the level of policy diffusion,and weak policy sustainability have severely restricted the effect of diffusion.It is necessary to seek solutions in terms of conceptual guarantee,organizational guarantee,resource guarantee,communication guarantee,and institutional guarantee.In addition,there are still some issues to be explored in the study: the transformation of governance innovation diffusion from the consciousness of the chief executive to the objective law,the transformation of special government governance innovation measures to the general law that can be copied and popularized,and the transformation of policy diffusion to effective governance. |
