中文摘要：

本文首先从生产函数概念出发分析了企业效率对企业绩效的影响，其次，选取我国制造业673家民营上市公司2005—2010年的非平衡面板数据，运用Metafrontier模型，估算了企业效率及技术差距，并与传统方法估算的企业效率进行比较，最后，实证检验了企业效率对企业绩效的影响效果。本文的研究结果表明：（1）不同企业的生产技术存在技术差距，在传统效率估算方法中，假设所有企业面对相同的生产边界过于理想。（2）在给定投入的前提条件下，企业生产技术的技术差距和此生产技术下的效率对企业绩效有正向的影响效果。（3）企业最优边界效率对企业绩效有正向的影响效果。（4）企业选择其生产技术后，可能由于企业经营者的“精力”有限，企业的技术差距与此技术下效率存在负相关关系。

英文摘要：

This article firstly analyzes the impact of the firm efficiency on corporate performance from the concept of the production function, Secondly, it selects 673 private listed companies from 2005 to 2010 unbalanced panel data as sample, by applying the Metafrontier model, estimates firm efficiency and technology gap, and then com- pares it with the firm efficiency estimated by the traditional methods. At last, it tests empirically the effect of the firm efficiency on corporate performance. The results of this study show that ： （ 1 ） The production technology of dif- ferent enterprises exist technology gap; it is too ideal to assume that all the enterprises face the same production boundary in the traditional efficiency estimation methods; （2） Given the production inputs, the production technol- ogy gap and the efficiency under the chose technology have a positive effect on corporate performance; （3） The firm efficiency of the optimal boundary has a positive impact on corporate performance; （4） After enterprises had chosen their production technology, and due to the limited energy of the manager, the technology gap and the efficiency under the chose technology is negatively correlated.
