| Managerial ability is one of the important indicators in evaluating performance. On the other hand, such capabilities and efforts by the management are not directly visible in the efficiency analysis of the decision-making units. Also, since natural gas as a clean fuel and low carbon source is one of the best energy sources in the world, so the gas company is one of the important institutions in the production of clean energy. So, in this article, an attempt has been made to measure the efficiency of 29 provincial gas companies and also to calculate their managerial capacity during three consecutive years 96, 97, and 98 and by identifying the contextual variables, the effect of each on the performance of these companies has been calculated. And then a ranking in terms of managerial ability is obtained for each of these units. For this purpose, during a three-step process, the efficiency of gas companies with the presence of contextual variables was calculated. In the first stage, the data envelopment analysis technique was used to obtain the technical efficiency of the units. Then, the technical efficiency logarithm obtained from the first stage was regressed on a set of contextual variables that affect the performance of companies. In the last stage, the managerial ability was extracted from the regression residue obtained from the second stage. Finally, knowing the managerial ability of each unit, a ranking was presented in this way. Finally, the results were analyzed. | ||
