In this study, I proposed a slacks-based measure of efficiency (SBM) in Data Envelopment Analysis (DEA). This measure takes account of input excesses and output shortfalls that are not involved in the radial measures of efficiency e.g. the CCR and the BCC measures. This measure (SBM) is defined as a ratio of two terms, one concerning with the output shortfalls, and the other with the input excesses, It was proved that SBM is not greater than the COR measure. SBM can be modified to cope with input-orientation as well as output-orientation. These modifications make easy the comparisons of SBM with the traditional measures of efficiencies. I then observed the dual side of SBM and found that it maximizes a virtual profit. As a consequence, SBM can be interpreted in terms of economics. Hence, price information on inputs and outputs can be incorporated in a similar way as the assurance region method and the cone-ratio model. Furthermore, I studied on the subjects such as decomposition of inefficiency into mix, technical and pure technical inefficiencies. These results will expand the application areas of DEA.

在本研究中，我提出了一个基于松弛的数据包络分析（DEA）的效率（SBM）的措施。这一措施考虑到了投入过剩和产出不足，而这些并不涉及效率的径向措施，例如CCR和BCC措施。该测度被定义为产出短缺与投入过剩之比，并证明了该测度不大于COR测度。SBM可以被修改以科普输入导向以及输出导向。这些修改使得SBM与传统的效率措施的比较变得容易。然后，我观察了SBM的两面性，发现它使虚拟利润最大化。因此，SBM可以从经济学的角度来解释。因此，投入和产出的价格信息可以以与保证区域方法和锥比模型类似的方式纳入。此外，我还研究了将低效率分解为混合低效率、技术低效率和纯技术低效率等主题。这些结果将拓展DEA的应用领域。
