The present research work was conducted to measure the efficiency of the cement companies in Indian Scenario by utilizing the concept of Data Envelopment Analysis during the pre and post period of recession during the recent global turmoil. In the present study two outputs (related to profit and sales) and three inputs related to cost are taken into consideration .Input oriented variable return to scale has been used for this paper. Linear program has been developed to measure the efficiency and super efficiency scores of the different cement companies. A further endeavour has been made in this paper to understand if recession really did have any impact on the cement industry by utilizing spearman rank correlation technique.

在经济衰退前后期间利用数据包络分析衡量印度水泥公司的效率

目前的研究工作是通过利用数据包络分析的概念来衡量印度情景中水泥公司在最近全球动荡期间经济衰退前后的效率。在本研究中，考虑了两个输出（与利润和销售相关）和三个与成本相关的输入。本文使用了面向输入的可变规模报酬。开发了线性程序来衡量不同水泥公司的效率和超级效率得分。本文进一步努力通过利用斯皮尔曼等级相关技术来了解经济衰退是否真的对水泥行业产生了任何影响。
