The Application Status and Outlook of CGE Model in the Construction Sector Under the Dual-Carbon Target

With the global warming and national dual carbon target in China, various carbon emission reduction models and methods at the macro level have been explored. CGE model is one of the main research models to solve environmental protection problem and also is a comprehensive research method. Two of the important applications of CGE model are in the environmental and carbon trading fields, respectively. The relevant literature on the CGE applications in the environment and carbon trading fields in Web of Science was first retrieved and then was analyzed by using literature visualization tool CiteSpace, and finally the current situation of application was reviewed. Correspondingly, in the field of construction, the CGE model has been adopted in environmental impact assessment at the macro level. But it is relatively less used. The main difficulty lies in the huge data demand, the limited abstract and expressions of the real economic situation, and linking the bottom-up micro-analytical model characterizing the construction sector with the top-down CGE model. Based on the research status of the application of CGE model, it can be indicated that the CGE model that represents the industry-related impacts and ripple effects will provide feasible research methods and models for future carbon trading research in the construction sector.
