绿色债券市场和能源行业股票市场的风险溢出效应研究

Study on Risk Spillover Eff ect of Green Bond Market and Energy Sector’s Stock Market

摘要: 本文使用四种多元GARCH模型分析中国绿色债券市场与传统能源行业股票市场之间的动态条件相关和波动性溢出效应。实证结果表明,DCC-GARCH模型拟合样本数据最好,并且能够利用该模型构建套期保值比率和最优投资组合权重。此外,在绿色债券和传统能源产业的股市之间,有着显著的动态关系,并且呈现较为明显地双向波动性溢出效应。最后,本文利用DCC模型中的条件波动率来估计套期保值比率,为投资者在绿色债券市场和传统能源股票市场上投资提出套期保值建议,以规避投资风险。

Abstract: This paper uses four multivariate GARCH models to analyze the dynamic conditional correlation and volatility spillover eff ect between the Chinese green bond market and the traditional energy industry’s stock market. The empirical results show that the DCC-GARCH model fi ts the sample data best and can be used to establish hedge ratios and optimal portfolio weights. This paper fi nds that there is a signifi cant dynamic conditional correlation between the green bond market and the traditional energy industry’s stock market, and a prominent two-sided volatility spillover eff ect. In addition, this paper uses the conditional volatility in the DCC model to estimate the dynamic hedge ratio and make hedge ratio suggestions for investors’ investment in the green bond market and the traditional energy industry’s stock market to avoid investment risks.
