本文沿用了已有文献中关于效率计量与分解的成熟方法，对我国三家油田上市公司与一家上市石油公司12个时期的技术效率与成本效率进行了详细的计量、分解与分析，得到的基本结论有：劳动力投入是影响我国油田上市公司产出的最重要的影响因素；油田的平均技术效率仅为0.61；产出项是影响成本的显著因素，这说明随着产出增加而出现的开采难度增加是导致开采成本增加的重要因素；油田的平均成本效率为1.47；全要素生产率的增长平均在10％左右，占到了产出平均增长率12.6％的79％，表明我国油田的生产率的提高主要是依靠全要素生产率的提高而实现的，只有21％左右的产出增长是依靠要素投入而实现的；前沿技术进步是油田全要素生产率增长的主要源泉，在2001～2004年期间，前沿技术进步对油田生产率的贡献高达17个百分点。
