2007年三季度以来,国际原油价格大幅上涨,屡创历史新高,一度接近每桶100美元,国家发改委一位负责人指出。导致近期国际油价不断上涨的原因非常复杂,“我们认为,影响本轮国际油价上涨的基本因素仍是供求平衡相对脆弱、投资基金炒作、地缘政治及石油生产国和消费国认识差别等四个方面。” Since the third quarter of 2007, the international crude oil price rose sharply and hit a record high repeatedly, once approaching 100 U.S. dollars a barrel, a person in charge of the National Development and Reform Commission pointed out. The reasons for the recent rise in international oil prices are very complicated. “” In our opinion, the basic factors affecting the current rise in international oil prices are still the relatively weak balance between supply and demand, speculation in investment funds, geopolitical differences in understanding between oil-producing countries and consuming countries aspect."
