我國(guó)實(shí)物資產(chǎn)與金融資產(chǎn)市場(chǎng)的動(dòng)態(tài)相關(guān)性研究——基于五元VAR-DCC-MVGARCH模型的系統(tǒng)檢驗(yàn)

【摘要】:資產(chǎn)市場(chǎng)間的收益和波動(dòng)相關(guān)性方面,許多已有工作并沒(méi)有形成一致結(jié)論。本文從周度時(shí)間跨度視角,構(gòu)建了VAR-DCC-MVGARCH模型,采用了2005年7月至2011年3月的交易數(shù)據(jù),在一個(gè)框架下考察了我國(guó)石油、黃金、利率、匯率和股票市場(chǎng)的動(dòng)態(tài)相關(guān)性。結(jié)果表明,利率對(duì)匯率、石油對(duì)匯率、黃金對(duì)利率、黃金對(duì)石油存在著單向均值溢出效應(yīng),僅在股票與黃金市場(chǎng)間具有雙向均值溢出效應(yīng);各市場(chǎng)波動(dòng)性之間均具有動(dòng)態(tài)時(shí)變特征,其中,股票與利率、匯率與利率、石油與匯率、黃金與匯率具有負(fù)相關(guān)性,股票與石油、股票與黃金、黃金與利率、黃金與石油間呈現(xiàn)出正向關(guān)聯(lián)。最后,將結(jié)果與現(xiàn)有文獻(xiàn)進(jìn)行了比較和探討。
[Abstract]:In terms of the correlation between returns and volatility in asset markets, much of the work has not reached a consistent conclusion. In this paper, the VAR-DCC-MVGARCH model is constructed from the perspective of time span, and the dynamic correlation of oil, gold, interest rate, exchange rate and stock market is investigated under a frame using the transaction data from July 2005 to March 2011. The results show that interest rate to exchange rate, oil to exchange rate, gold to interest rate, gold to oil have one-way mean spillover effect, and only have two-way mean spillover effect between stock and gold market. Among them, stock and interest rate, exchange rate and interest rate, oil and exchange rate, gold and exchange rate have negative correlation, stock and oil, stock and gold, gold and interest rate, There is a positive correlation between gold and oil. Finally, the results are compared and discussed with the existing literature.
