摘要
如何正确地引导社会资本流向绿色和环保项目,以促进企业的绿色和低碳转型,成为当前中国经济可持续发展的重要问题.在此背景下,论文提出了含ESG投资和突发性冲击风险的均衡投资组合模型,理论结果表明:1)投资组合的预期收益与组合自身和市场的ESG水平、外生冲击风险等因素有关;2)当存在外生冲击时,ESG水平对组合预期收益率的影响与受到的冲击程度正向相关.论文以我国股票型基金和新冠疫情为自然实验对理论结果进行了实证检验,并进一步分析了ESG投资水平对基金绩效影响的理论机制,所有实证结果均与理论预期高度吻合.本文的研究将有助于引导社会资本通过ESG投资方式,流向企业的绿色和环保项目,为金融资本促进企业绿色转型提供了有价值的理论和实证依据.
How to correctly guide more capital to green projects and promote the transformation of enterprises to the green and low carbon emission have become a hot issue for the sustainable development of China.In this background,the paper proposes an equilibrium investment decision model with ESG investing and exogenous sudden shock.The theoretical results show that:1)The expected return of portfolio is related to the ESG level from the market and the portfolio itself;2)The impact of ESG level on the expected return of the portfolio is positively dependent on the degree of sudden shock when there is a sudden shock to the market.Using COVID-19 shock as a national experiment,all theoretical results are checked empirically by the stock funds data,and the impact mechanism of the ESG level on the fund performance are further analyzed.The empirical results are highly consistent with the theoretical prediction.The research of this paper will help guide social capital to the green and environmental protection projects of enterprises through ESG investment,or rather provide valuable helps for financial capital to promote green transformation of enterprises.
