The beginning of the XXI century is characterized by global changes in the economy and society that led to the backwardness of the social sciences from real life. In that regard, the increasing demands on science, which must contain creative tools in the spirit of the time are growing. The toolkit of any one of the social sciences is not enough to describe the processes in all spheres of human life. This can only be achieved on the basis of interdisciplinary connections of all social sciences. There is a problem of finding a form in which such a combination of interdisciplinary relationships in the social sciences will be expressed. In this paper, the historical aspect of the search for attempts to find such a form is investigated. We consider the full form to display the categories and methods of different sciences methodology of economic imperialism. There are two reasons to think so. The first is the universality of economic methods to the movement of the chain social phenomenon – modeled problem – practice and conclusions enriching science. The second is the priority of the economic sphere in any society, which is a powerful engine of social transformations. The purpose of this research is to develop theoretical views about economic science and the beginning of XX century identify and systematize trends in its development, taking into account the influence of globalization factors, review of the main forms of interdisciplinary transitions in general and «economic imperialism» in particular as a perspective direction in the development of a united social science. Research of this problem requires the use of certain methodological tools. On the basis of unity of historical and logical approaches, the evolution of economic imperialism in the context of the development of social sciences is considered. Using functional approach, the logical-functional relationships between economy and law are investigated. Examples are given not only to the invasion of economic imperialism in other sciences, but also to examples of mutual coexistence. The ultimate goal of «economic imperialism» is the unification of all the sciences about a society based on neoclassic.
