since the birth of human society, there has been no real equal subjects in economic activities. Equality of subject is only a kind of fiction on the subject of economic activity from laws. Economic law publicly acknowledges the inequality and differences of subject, and the existence of the advantaged and disadvantaged subjects. Economic law forms its unique model by restriction and protection of these subjects. The establishment of fair value of economic law indicates that the model is transformed from tradition to modernization. Modernization process and features of the model show that the restriction and protection model of the advantaged and disadvantaged subjects is the perfect combination of two theories in economic law history, which precisely positions the field and the limit of "hand of the market" and " hand of the government", profoundly reveals the real effects of the economic law, and leads economic law to the right track of development.
