چکیده:
The commercial viability and feasibility of projects in oil and gas industry mainly depends on the economic efficiency. The evaluation of the determinants of economic efficiency in Oil & Gas industry can help the energy companies to achieve competitive advantage. Therefore, this dissertation studies to study economic efficiency of the gas production in Iran’s gas refineries using the returns to scale indicators: economies of scale and economies of utilization. The aim of this dissertation is measuring and analyzing the economic efficiency of gas production in Iran. The results of this study can be used to improve the productivity and economic performance of the gas production in gas refineries. Also, the results of the analysis can be used to assess impact of gas production policies and recommend better policies to improve production efficiency in gas refineries. Upon it we can assess the impact of previous policies and use appropriate ones, if it will be necessary. For this purpose, this study employs a dual cost model using an applied econometrics method. This dissertation estimates a system of Translog cost function along with cost share equations using Seemingly Unrelated Regression Equations (SURE)
method with a panel data of seven gas refineries over the period 1382 to 1393.
The results of the economic efficiency indicators of gas production shows the economic inefficiency of gas production in gas refineries during 138293; as both economic efficiency indicators in all years over the study period. Economies of scale and economies of utilization indices are less than one for all gas refineries. As evidence, during the period under review, the average economies of scale coefficient for Sarkhon-Qeshm, BidBoland, Ilam, Pars-e-Jonobi Gas Complex, Fajr-e-Jamm, Parsian, and Hashemi-Nejad refineries are 0.29, 0.26, 0.37, 0.14, 0.18, 0.11, and 0.38, respectively. Also, the same figures for economies of resource utilization indicator are 0.68, 0.68, 0.82, 0.57, 0.62, 0.58, and 0.74, respectively.
Reasons of economic inefficiency in the Iran’s gas refineries can be considered from two different perspectives. One of the views is obstacles and problems in the body of gas industry and management of gas production. And other is challenges and issues facing Iran’s the economy particularly production inefficiencies in the Iranian economy. However, in order to improve the efficiency of gas production in Iran’s gas refineries some measures are required to be used such as use of appropriate production technologies, increasing economic life of refineries, and promoting research and development, and so on.
