C3IAM/GEEPA includes 27 sectors, which are paddy rice, wheat, cereal grains, vegetables and fruit and nuts, oil seeds, sugar cane and sugar beet, plant-based fibers, crops, cattle and sheep and goats and horses, animal products, raw milk, wool and silk-worm cocoons, forestry, fishing, coal, oil, gas, other minerals, other manufacturing, energy-intensive manufacturing, roil, electricity, gas manufacture and distribution, water, construction, transportation service industry and other services (shown in Table 1 below). C3IAM/MR.CEEPA covers 31 provinces and municipalities (without Hong Kong, Macao and Taiwan due to data availability) of China and includes 23 sectors (see Table 2 below).

In the production module, we assume that each sector produce only one commodity, and the inputs of each sector include labor, capital, energy, and other intermediate inputs. In addition, the production of each sector is represented by a nested constant elasticity of substitute (CES) function, as shown in Equation (1). The CES function is characterized by the flexibility to reflect the alternatives between producers and consumers based on the price and cost. For example, if carbon pricing policies are implemented in the economy, the producers will choose to use lower-carbon energy for its production activities due to increases in the cost of high-carbon energy, thus promotes the economy transition from high-carbon energy to clean energy.

(1)

Where  refer to the output of sector  in region , is the input of sector  in region , is shift parameter, is the share parameter,  is the substitution parameter, is the elasticity of substitution.

In C3IAM, the substitution of production functions consists primarily of substitutions between electricity and non-ELEC bundle, energy aggregate and capital, as well as energy-capital aggregate and labor.
