双碳政策对相关企业羊群效应的影响

The Impact of Dual Carbon Policies on Herd Behavior in Related Enterprises

摘要: 我国针对二氧化碳排放引发的环境问题，于2020年提出了双碳政策，并于2021年开放碳交易市场。本文通过分析制冷与能源行业企业的股票表现，研究双碳政策的时候相关行业是否存在羊群效应。研究发现，在政策提出初期，碳交易市场开放前，相关行业由于政策引导、信息不对称和资源分配有限等原因，存在显著的羊群效应。然而随着碳交易市场的开放，市场机制成熟、信息透明度提高和减排成本降低等原因，使得羊群效应减弱。基于以上结论，本文建议：政府应完善相关政策与制度，减少信息不对称并加强监管，促进市场公平良性竞争；企业应根据自身情况制定低碳转型策略，逐步推动技术创新与内部管理，避免出现盲从现象，实现经济效益与环保目标的平衡。

Abstract: In response to the environmental problems caused by carbon dioxide emissions, China proposed the dual carbon policy in 2020 and opened the carbon trading market in 2021. This article analyzes the stock performance of companies in the refrigeration and energy industries to study whether there is herd behavior in related industries when implementing the dual carbon policy. Research has found that in the early stages of policy formulation and before the opening of the carbon trading market, there is a significant herd effect in related industries due to policy guidance, information asymmetry, and limited resource allocation. However, with the opening of the carbon trading market, mature market mechanisms, increased information transparency, and reduced emission reduction costs, herd behavior has weakened. Based on the above conclusions, this article suggests that the government should improve relevant policies and systems, reduce information asymmetry, strengthen supervision, and promote fair and healthy market competition; Enterprises should develop low-carbon transformation strategies based on their own situation, gradually promote technological innovation and internal management, avoid blind obedience, and achieve a balance between economic benefits and environmental protection goals.
