【摘要】 建立碳排放权交易市场和绿证市场是中国实现“双碳”目标的重要策略。然而，现有研究多从发电商的经济角度分析市场耦合关系，忽视了用户进入碳市场的情况。针对这一不足，本文提出了尿素商参与电碳证市场双层优化模型，引入用户参与碳市场的决策机制，从利润和碳减排两个角度，研究尿素商这一特殊用户对市场主体决策的影响。结果表明，尿素商参与电碳证市场能产生“1+1>2”效应；尿素商参与碳市场可显著提高耦合市场的整体效益；提升绿证比例和降低碳配额会减少尿素商的产量。由此，本文提出国家应大力发展完善碳证交易机制，加快尿素行业能源消费电气化以及碳市场的纳入等建议。更多还原

【Abstract】 Establishing carbon emission trading markets and green certificate markets is an important strategy for China to achieve its“dual carbon”goals.However, existing research mostly analyzes market coupling relationships from the economic perspective of power generators, ignoring the situation of users entering the carbon market.In response to this deficiency, it is conside-red that urea suppliers are manufacturers that use carbon dioxide as a production factor, and the impact of participating in the market as users.A dual layer optimization model for urea producers to participate in the carbon certification market was proposed, introducing a decision-making mechanism for user participation in the carbon market.From the perspectives of profit and carbon reduction, the impact of urea merchants as a special user on market decision-making was studied.The results indicate that the participation of urea producers in the carbon certification market can generate a“1+1>2”effect.The participation of urea producers in the carbon market can significantly improve the overall efficiency of the coupled market.Increasing the proportion of green certificates and reducing carbon quotas will decrease the production of urea producers.更多还原
