Understanding the Crude Oil Price: How Important Is the China Factor?
利用1997年1月至2010年6月中国月度净石油进口数据，通过向量自回归分析发现中国净进口增长对月度油价变化无显著影响，且两者间无格兰杰因果关系，历史分解显示中国需求冲击在2002-2008年油价上涨中作用较小。
This paper employs monthly data on China’s net oil import from January 1997 to June 2010 to assess the role of China’s net import in the evolution of the crude oil price. Based on a vector autoregression (VAR) analysis, we find that the growth of China’s net oil import has no significant impact on monthly oil price changes and there is no Granger causality between the two variables. The historical decomposition indicates that shocks to China’s oil demand have only played a small role in the oil price run-up of 2002-2008. We also calculate the price changes implied by China’s net oil import growth from a longer-term supply and demand shift perspective. doi: 10.5547/ISSN0195-6574-EJ-Vol32-No4-4 “Surging Chinese demand is underpinning the recent spike in the price of oil, figures from the International Energy Agency (IEA) show. This ‘China factor’ has more bearing on oil prices than the ‘risk factor’ coming from global tensions, some experts say” —CNN (2004) “The price of crude oil could soar to $200 a barrel in as little as six months, as supply continues to struggle to meet demand . . . Soaring global demand for oil is being led by China’s
