欧盟碳市场价格波动与风险度量研究欧盟碳市场价格波动与风险度量研究

摘要：

欧盟碳市场旨在通过碳排放权的交易机制，实现温室气体排放减排目标，并作为一种可再生能源的激励机制。然而，自碳市场的正式运营以来，碳价格波动不断，交易风险也越来越高。因此，本论文以欧盟碳市场为研究对象，探究碳价格波动及交易风险的因素，借助VAR-GARCH模型对欧盟碳市场价格波动进行模拟和预测，利用ValueatRisk（VaR）和ExpectedShortfall（ES）方法对欧盟碳市场的风险进行度量。研究显示，欧盟碳市场价格受到多种经济因素的影响，包括宏观经济环境、碳市场供需关系、汇率等，且存在显著的季节性效应。此外，欧盟碳市场的交易风险主要来自市场波动性和不确定性的增大，通过VaR和ES方法的度量可以较好地反映这种市场风险。本研究对于掌握欧盟碳市场价格走势、降低交易风险具有重要的参考价值。
