Abstract: It is of great importance for oilfield companies to improve business performance and fulfill the cost-effective objective under the background that international oil prices continue to remain at a low level. Based on the DEA model and Malmquist index, this article makes static and dynamic evaluations on business performance of 24 typical Chinese listed oilfield service companies between 2011 and 2015. It points out that China’s oilfield service industry is not perfect enough in business management and system construction. The State-owned oilfield service companies are better than their privateowned counterparts in the areas of average integrated efficiency, pure technological efficiency and scale efficiency. Most of listed oilfield service companies in China were under the scale and remuneration increasing period between 2011 and 2015. Appropriate restructuring of assets can benefit oilfield service companies to improve their business performance under the environment of low oil prices. Therefore, it is necessary to continually perfect the oil and gas industrial operation and supervision mechanisms and grasp the strategic opportunity of the country’s the Belt and Road, actively open up overseas market and expand business scale, accelerate technological investment, and energetically promote technological innovations. Importance should be attached to the role of capital market while the efforts are strengthened for fine management of business process and seamless combination of various production links.
