|General equilibrium (closed economy)
C3IAM belongs to a class of integrated assessment model. In C3IAM, there are multiple independent but interactive modules, including three socio-economic modules (GEEPA, MR.CEEPA and EcOp), one technology module for China (NET), one land-use module (EcoLa), one climate module (Climate) and one loss module (Loss). Thus C3IAM integrates the global CGE, economic optimum growth, revised earth system, land use and impact models, dynamically captures the long-term optimal economic growth and climate change mitigation and adaptation. C3IAM is a flexible framework that can be applied to a variety of economy-climate-energy-environment issues. The trade of goods and services is also considered.
In C3IAM, GEEPA and MR.CEEPA are implemented for GAMS/MCP (Mixed Complementarity Problem), and PATH is used as a solver; EcOp is implemented for GAMS/NLP (Non-Linear Programming, and the solver is MINOS; NET is implemented for GAMS/LP (Linear Programming) and the solver is CPLEX; the parameters in Climate module are calculated with R and EcoLa is run by MATLAB. Generally, the C3IAM is a dynamic model using a 5-year time step.
