In the between selective companies Razi company has the best performance. This company in the 1384 and 1385 years has the strict efficiency and returns to scale is constant.The results also reveal that state-owned companies have the decreasing returns to scale. So; the efficient policy for these companies is to reduce economic scale and decrease inputs.
