初始分配对电力行业碳交易效率影响的实验研究

An Experimental Study on Initial Allocation of Permit’s Inference on Carbon Emission Trading in the Electricity Industry

摘要:

电力行业作为我国国民经济中最大的二氧化碳排放部门,面临巨大的减排压力。本文以我国火电企业减排成本为基础,利用实验室实验研究在双向拍卖的碳交易中,许可证初始分配对电力行业碳交易效率的影响。实验通过改变许可证初始分配方式构造了对称/垄断和不对称/寡头两个实验设置。对成交价、IMTE指数、成交量和交易效率四个实验结果的分析表明,说明双向拍卖制度能够抑制因初始分配方式差异造成的市场势力。

Abstract:

The power industry, asSthe largest carbon dioxide emissionsSdepartments in national economy of our country, is facing tremendousSpressure to reduce emissions. Based on abasement cost of thermal power, this paper reports a laboratory experiment to examine carbon trading efficiency of power industry which influenced by the initial permits’ allocation in double auction carbon trading. By varying the initial allocation of permits, the experiment constructs two treatments. One is Symmetry/Monopoly, the other is Asymmetry/Oligopoly. The experimental results, such as price, IMTE, transaction volumes and trading efficiency, shows that Double Auction system can suppress the market power caused by differences in the initial allocation.
