There are some problems in local legislations of scope of accepting cases brought by a procuratorial authority for public interest. Their regulations about “within” range seriously repeat with host law，and extended scope of “similar” is too wide，and the scopes of accepting cases with civil and administrative are mixed up. Their regulations not only does not conform to the rule of legislation law，which stipulates local legislations should be refined host law’s regulations，also might have beyond legal reservations and create new rules. In terms of the limitation of the scope of “within”，local legislations should establish a repeat legislative review mechanism，and urge local lawmakers to formulate laws that are more specific than central legislation according to the actual situation of their own regions. In the limit of the scope of “similar”，we should change the legislative status of mixing civil and administrative. For civil procuratorial public interest litigation，the connotation of social public interest is defined from three aspects of interest subjects，the scope of interest involved and the content of interest，and the matters that can be handled by the autonomy of private law are excluded from the category of public interest litigation. For administrative procuratorial public interest litigation，the scope of “similar” is limited to the duty of administrative organs of safeguard national interests and social public interests，and the causal relationship between improper exercise of public power and damage is taken as the standard to define the scope of administrative public interest litigation.
