Since the reform and opening-up,the main approach of procuratorial organs in serving economic and social development has been through criminal prosecution.The proposal of the"Four Major Prosecutions"provides the procuratorial organs with the possibility to serve economic and social development through a broader approach.The characteristic of administrative prosecution enables it to regulate administrative law enforcement and promote fair justice,which is in line with the requirements of constructing a legalized business environment.In practice,administrative prosecution has supervised the phenomena of relevant authorities not actively fulfilling their duties and improperly exercising power in the field of legalized business environment,and guided enterprises to carry out administrative compliance construction.Administrative prosecution has made many beneficial explorations in the field of legalized business environment,but there are also shortcomings such as insufficient work system,misalignment between supervision focus and practical needs,and blurred boundaries of power exercise.The improvement direction should be to strengthen the organizational advantages of integrated prosecution so as to empower administrative prosecution work,and to delineate the boundaries of administrative prosecution duties based on the process of national division of powers and clear supervision targets.With the core objectives of supervising administrative illegal acts,improving the efficiency of people's court litigation,and reducing the cost of safeguarding the rights of market entities,the principle of proactive performance of duties should be followed,and the potential roles of administrative prosecution should be expanded,so as to shape the working system of administrative prosecution optimizing the legalized business environment.
