摘　　要：不同的碳排放权交易机制之间有何内在促进和制约关系,排放权交易市场中企业的决策标准是什么,为何发达国家热衷于实行CDM项目,碳税的加入对排放权交易市场有何影响。围绕这一系列重要问题,本文从微观角度出发,在AIM-Enduse模型的基础上加入新的目标函数,重新定义参数,修改约束条件,构建在排放权交易机制下企业减排的单阶段最优化决策模型。在此模型基础上,本文分析了基于配额的排放权交易和基于项目的排放权交易(CDM)之间内在的促进和制约关系,进而发现,参与者数量及参与者之间减排边际成本的离散程度将决定排放权交易市场的交易量;对于减排技术高度发达的国家来说,CDM机制不仅有利于大幅降低其减排成本,还有利于增加排放权交易市场的交易量,但是对于减排技术较为落后的国家来说,CDM机制对其几乎没有影响。Are there any internal promotion and restriction relationships among different carbon emission trading systems？ What are decision-making standards of enterprises in emission trading markets？ Why developed countries fall over themselves for clean development mechanism （CDM） ？ What are the impacts of carbon tax on emission trading markets？ In order to answer those series important question, this paper, from the micro-economic perspective, revises the AIM-Enduse model by adding new object function, redefining the variables and changing some of the constraints to construct a singlestage optimizing model of enterprises＇ carbon emission reduction under emission trading systems. Based on the new model, we analyze the internal promotion and restriction relationships between the permit-based emission trading and project-based emission trading （CDM） and further find that the number of participants and the variance of marginal cost of emission reduction determine the trading volume of emission trading markets; CDM can help those countries with advanced emission reduction technologies not only reduce emission reduction cost but also increase the trading volume of emission trading markets, but CDM hasn＇t significant influences on those countries without advanced emission reduction technologies.
