Research on International Carbon Emissions Trading and Optimal Exports Scale of China Carbon Emissions

This paper reviews the researches related to international carbon emission right trading. Based on the analysis of marginal abatement curves theory, it has been demonstrated that the fact that different countries or districts have different marginal abatement costs of carbon emission upon respective abatement promise gives rise to international carbon emission right trading. Furthermore, this paper proposes that developing countries should actively participate in the international carbon emission right trading in order to obtain due market benefits. Then, on the basis of the two-phase model, this essay also discusses the optimal exports scale of carbon emission right and its determinant factors, and evaluates the optimal export quantity of carbon emission right for China at the first phase.
