وابستگی شدید ارزش بین قیمت نفت خام و بازارهای سهام چین

This paper examines the asymptotic dependence between the Chinese stock market and the world crude oil market based on the Extreme Value Theory (EVT) and finds a positive extremal dependence. We explain this positive dependence in terms of economic cycles due to the co-movement between the Chinese stock market, the world oil market and the global economic cycle. EVT satisfactorily captures the Chinese special oil price adjustment mechanism. We also examine the contagion effect and find that the dependence level tends to increase dramatically during the crisis period but that the simultaneous booms between these two markets decrease considerably after the crisis.
