摘要
本文以"双碳"为背景,研究气候风险对四川省矿产上市公司的影响.首先,本文以 2014-2022 年东方财富网络数据为样本,采用朴素贝叶斯模型构建气候情绪指数.其次,采用多元模型进一步研究气候情绪对四川省上市矿产公司总资产报酬率的影响.实证结果表明:本文构建的气候情绪指数与四川矿产上市公司的总资产报酬率存在显著正向关系;气候风险对不同公司类型影响不同,气候情绪对大规模矿产公司的总资产报酬率有显著的促进作用,而对小规模矿产公司总资产报酬率不存在显著影响.因此,为了更好地应对气候变化风险,矿业企业应积极实施低碳战略,主动披露排放信息,提高品牌价值,为长期发展创造新的竞争优势.
Abstract
This paper investigates the impact of climate risk on listed mineral companies in Sichuan Province against the backdrop of the"Double Carbon"goal.Firstly,utilizing data from 2014 to 2022 obtained from the East Money Net-work and constructing a climate sentiment index with the Naive Bayes model.Subsequently,a multiple regression model is employed to further examine the influence of climate sentiment on the return on total assets of the listed mineral compan-ies in Sichuan.The empirical results indicate that the climate sentiment index constructed in this paper has a significant positive relationship with the return on total assets of Sichuan's mining listed companies.Climate risk affects different types of companies differently,significantly enhancing the return on total assets for large-scale mineral companies,while showing no significant impact on small-scale mineral companies.Therefore,in order to better manage the risks associated with climate change,mining companies should actively implement low-carbon strategies,proactively disclose emission in-formation,and enhance brand value to create new competitive advantages for long-term development.
