| Summary: | In the context of the global value chains and international trade rapid development, the links among different countries have become closer and more complex. The differences in the role of trade in economic, energy, and environmental formation in different countries, sectors, or different regions and sectors within the same country are becoming increasingly apparent. Structural path analysis (SPA) is an important method to study the transfer influence and path relationship between different factors in the production supply chain. This article mainly summarizes and analyzes the literature on the application of SPA in economy, environment and energy. First, introducing briefly the concept, model and application of SPA. Second, specifically analyze and summary the main application scope and field of SPA. Based on the summary of the literature, the following prospects are proposed for subsequent research: use SPA to explore the formation path of added value; Extend the single-region SPA model to a multi-region form to study the path of economic, environmental and energy formation and the impact of different factors on the global perspective; combine with a trade spillover model to analyze trade spillover effects of economic, environmental and energy.
