无论从石油的资源量、产量还是从出口量来看，欧佩克都是全球最重要的石油供给方集团，且该组织在国际石油市场上的重要性仍在稳步提升。不过，从组织机制来看，近些年由于受产量约束机制不断松动，配额遵守率不断下降的影响，欧佩克的卡特尔属性也在不断弱化。目前，欧佩克国家中，仍在积极影响国际石油市场的主要是以沙特阿拉伯为首的少数核心国家。在石油政策方面，欧佩克当前执行的石油政策旨在维持石油市场“适度”紧张的状态，这一政策虽然无助于平抑国际油价的短期波动，但对于维持和影响21世纪形成的高油价均衡起到了十分重要的作用。
From the perspective of resources，production and exports，OPEC is the world’s most important oil supplier，and its importance in the international oil market is still rising steadily in recent years. However，from the point of view of organizational mechanism，due the reason that production constraint mechanism keep loose，quota observance rate keep falling，OPEC is also gradually losing its cartel glamour. In OPEC，only several core countries led by Saudi Arabia still delivers influences to the international oil market positively at this moment. And for the current oil policies，OPEC devoted itself to keep the oil demand and supply on a “modest” tense balance. Although this policy does not help to dampen short-term fluctuations of oil prices，it is still very important for maintaining and influencing the high oil prices equilibrium formed in the new century.
