Abstract: Network research is becoming one of the most active and most attractive research fields in economics. This paper not only discusses how network analysis method brings a new perspective and a new tool to economic study, also analyzes the superiority of the economic framework to research of network formation problems compared to the traditional network analysis paradigm and sociology paradigm On this basis, we especially emphasize the integration of economics research framework and network analysis methods. Under this integration perspective, we are concerned about the new viewpoints and discoveries arising from micro shocks and macro fluctuations, market power and pricing, market competition and efficiency, and labor market inequality. The integration of mainstream economics research framework and network analysis method is the convergence of the horizon between " economic man” and the " social man”.
