Research on the Application of Network Analysis Methods in Macroeconomics

Abstract

This paper explores the application of network analysis methods in macroeconomics, focusing on its role in international trade, financial systems and industrial chains. Network analysis reveals complex interactive relationships that are difficult to capture in traditional models by constructing connections between economic entities, especially in policy transmission and systemic risk identification. This paper reviews in detail how network structure affects policy transmission effects, and explores the contribution of network analysis to policy effect evaluation, especially in crisis management and risk prevention and control. Studies have shown that network analysis methods can help identify key nodes in the economic system, optimize policy design, and improve the system's risk resistance, thereby providing scientific support for macroeconomic policy making.
