摘要
“双碳”背景下中国能源结构面临深度调整,能源市场不确定性加大,在此背景下深入探究能源市场与股市间的波动溢出效应,对于推进我国能源市场价格机制改革、防范金融风险跨市场传染具有重要意义。本文采用TVP-VAR-DY模型研究了中国煤炭、石油、天然气三类能源市场与A股市场的时变波动溢出效应。结果表明,煤炭、石油、天然气市场与股市之间的波动溢出效应存在明显的时变特征:从静态溢出效应来看,原油市场与股市之间的波动溢出效应明显强于煤炭和天然气市场,说明能源市场与股市的波动溢出效应与能源商品的“金融化”程度密切相关;从动态溢出效应来看,溢出水平对于极端事件较为敏感,当股市崩盘等极端事件发生时,能源市场与股市的波动溢出指数明显上升;最后,从方向性溢出和动态网络分析来看,各市场的方向性溢出以及溢出网络的结构特征均会随经济金融环境不断变化,且原油市场和股票市场表现出更加明显的时变特征。
