Measuring productivity growth of the regional electricity companies with regard to sanctions and related policies

Productivity growth in each industry is one of the important factors for managers which may have strong influence on the decisions and policies. On the other hand، sometimes we are faced with some conditions that their influence in the industry is inevitable، therefore، using an exact mathematical model to measure it as a prerequisite for presenting guidelines، proper policies and promoting productivity، seems to be necessary. This paper measures total factor productivity growth of 14 regional electricity companies since the end of the fourth development plan (1388) to start the fifth year (1389) with regard to sanctions reviewing electrical industry which has a special role in the energy sector in the country. For this purpose، the indices of these companies have been developed as inputs and outputs and the extended Malmquist index including components of pure efficiency change (PEC)، scale efficiency change (SEC)، balanced factor change (BFC) and extended technology change (ETC) will be used. The results will make appropriate analysis tools for managers in order to decision support and providing guidelines in accordance with the Companies conditions related to each mentioned components.
