Measurement and evaluation of efficiencies of companies in chosen branch

My work dwells on measurement and evaluation of efficiencies of companies and on sector analysis of energetic branch. We can regard the efficiency with various points of view. Generally we can define it as an ability of company to valorize as much as possible the assest that was put in it. At first my work is engaged in measurement and control of the efficiency of companies and in value control of efficiency. After that follows the summary of traditional and modern indicators of efficiency with account of their advatnages and shortcomings. Then I mention some instruments and concepts that contribute to increases of efficiency. The last part of my work contains case study, where I analyse the efficiency of companies acting in energetic branch by means of benchmark study
