Currently, the economic law enforcement is the weak point of the research on economic law. The purpose of this paper is to find ways to solve the problem. Changing the single regulation thinking of public enforcement and paying more attention in private enforcement is the meaning of developing the theory of economic law. Modern society is rich in private legal resources. Private have already play an important role on the public damage area. The research methods of economics provides a good reference for us. The private with the “economic man” feature have the function of covering the public enforcement shortage, collecting information and guiding public opinion on economic law which focus on the public interest. We conclude that it needs to be explored from two aspects of entity and procedure. Establish a compound system of public and private enforcement and public interest litigation system is the key path of the improvement of the economic law enforcement theory and the efficiency of law enforcement.
