Computable general equilibrium (CGE) model practice technology in resource environment under the goal of "double carbon"

      Our government promises to 2030 Years of implementation “ Carbon reaches its peak ”,2060 Years of implementation “ Carbon neutralization ”, This is it. “ Double carbon ” The goal is . In order to achieve this goal, we must apply various alternative technologies with high carbon dioxide emissions , Not only technical reliability needs to be considered , We also need to consider the economic feasibility . Computable general equilibrium model （CGE Model ） Because it can simulate the operation of macroeconomic system and price regulation mechanism , Analyzing the impact and effect of policy tools has attracted much attention “ Double carbon ” Favor of target researchers . because CGE The model is based on a rigorous microeconomic foundation , The threshold for researchers in non economic fields is very high ; And influenced by the tradition of economic research ,CGE Models are mostly used GAMS And other engineering researchers are not familiar with the establishment of software . For the benefit of researchers in the fields of ecology and environment CGE Model , Reduce the threshold for engineers and technicians to apply the model , Special call based on R Linguistic CGE Model practice technology application course .
