Energy price in Iran and changing fuel consumption technology

Do Iranian industrial manufacturing improve fuel consumption technology, and what is the intensity of this improvement? These technology adoptions are crucial due to the long-term effect on energy consumption.
To answer this question and by studying the changes in the period 2012-2017, this paper tries to figure out what will change the firms' decision on energy usage technology. The results show new firms have to decide on their technology due to the reduction in total energy prices.
The findings of this study show that whether the changes in technology use are limited to new entrants, or we consider it a reduction over time, technological changes due to price in the data of industrial manufacturing have occurred. Also, according to the theoretical foundations, based on the findings of this study, with increasing the firm's age, the tendency for structural changes in the industry will decrease.
