摘要
碳排放交易作为一种市场化的碳排放控制手段,近年来愈来愈受到人们的关注。通过构建VAR-BEKK-MGARCH模型对碳排放交易价格、动力煤价格和煤炭企业的股票价格三者进行回归后发现,在均值方面煤炭企业股票价格均值会对煤炭价格和碳排放交易价格的均值产生显著的溢出效应,而碳排放交易价格均值的变动也会对煤炭价格的变动产生显著的溢出效应;在波动方面,煤炭价格的波动会对碳排放交易价格的波动产生显著的溢出效应。碳排放交易价格波动对煤炭企业股票价格的波动、煤炭企业股票价格波动对煤炭价格波动和碳排放交易价格均具有显著的溢出效应。
As a market-based means of controlling carbon emission,carbon emission trading has attracted more and more attention in recent years.In this paper,after the regression of carbon emission trading price,thermal coal price and the stock price of coal companies by constructing the VAR-BEKK-MGARCH model,it is found that the mean value of coal enterprise stock price will have significant spillover effect on the mean value of coal price and carbon emission trading price,and the change of the mean value of carbon emission trading price will also have significant spillover effect on the coal price change.In terms of fluctuation,the fluctuation of coal price will have a significant spillover effect on the fluctuation of carbon emission trading price.The fluctuation of carbon emission trading price has significant spillover effects on the fluctuation of coal enterprise stock price,and the fluctuation of coal enterprise stock price on coal price fluctuation and carbon emission trading price.
