摘要

Dynamic relationship between gold and oil market has attracted increasing amounts of scholarly interest. In this paper, we propose a novel nonlinear analysis framework including VAR-BDS, ARIMAX-BDS, non-parametric structural change detection model, DCC-GARCH model to clearly reveal the time-varying correlation between the crude oil price and the gold price after the 2008 GFC. Firstly, the results of VAR-BDS and ARIMAX-BDS show that the interactions between these two markets are suggested to be nonlinear in contrast to previous work. Secondly, by employing non-parametric structural change detection model, we find that the linkage between oil and gold market after the 2008 GFC experience nine different regimes and turn to be nonlinear and asymmetry. Finally, DCC-GARCH model is adopted to examine the different interactions in the case of different regimes depending specific threshold variables. In the end of our paper, some significant implications are summarized, and the link between oil and gold market has go through a nonlinear, dynamic and asymmetric evolution process, also our conclusions present a comprehensive and timely reference information for different market participants confronting with similar global risks.
