Abstract: The approval of enterprise investment project is of pivotal role for local government to intervene economic activity. The local government in Keqiao District of Shaoxing carried out a systematic reform, such as delegating approval authority on demand, making related policies, establishing coordination mechanisms and accountability system, standardizing intermediary services, optimizing the "five linkage" mechanism, and proxy mechanism, which innovates the use of the coordinated processing methods, shortens the processing time, strengthens the intermediary management, and makes innovation of the approval system accessible to others. But there are still some difficulties, such as excessive service invading enterprise autonomy, excessive compression of approval time affecting intermediary service quality, and post regulation needing to be further strengthened, which shed lights on further reforms such as the government should define the boundaries of power, pay attention to participatory demonstration, strengthen social regulation, introduce performance evaluation of administrative approval system reform, and improve the online approval.
