Abstract

In today’s world, considering economic, social, cultural political and marketing conditions of institutional units, limits of recourses and importance of efficiency in order to achieve ideological goals is instrumental. Regarding certain governing principals of water and wastewater industry, price controlling by government in particular upgrading efficiency can solve a big portion of industry’s problems. In this research, Performance of financial factors such as liquidity, economic activity, profitability and investment with data envelopment analysis is compared to the common method of assessing factors in 20017 in the domain of urban water and wastewater industry. Because of non-homogeny of statistical population, the focus was on the company’s parameter differential. The results show that the data envelopment analysis can determine the efficiency in administrative planning and deciding with high precision. According to the research results, the holding companies of water and wastewater industry greatly vary in efficiency. Also after grouping the holding companies to 5 independent groups with some certain factors, there is a significant difference between financial efficiency and size of companies with assuming constant return to scale and if assumed variable return to scale there is no significant difference.
