Growth rate of exports in this period shows increase in all of the subsectors, and the maximum increase of 23.5 % belongs to the subsector of textile manufacturing productions.
Based on the maximum likelihood test, the hypothesis of the equality of frontier function in all of the subsectors, except the basic metal industry (BMI) subsector, was rejected, and this indicates that these functions can separately be estimated.
On the other hand, import growth rate is also positive in all of the subsectors and the maximum rate of 16.9%% relates to the oil and oil derivatives subsector.
To compensate for this difference in choosing appropriate function form for the all groups of the subsectors, estimators have been obtained by using the both functions form.
Gamma coefficient in all of the small units of the subsectors (except for the subsector of FOP) and in all of the medium and large units (except for the WPP subsector) is significant, and this indicates the inefficiency in all of the subsectors.
The percentage of public R&D investment in all three subsectors increased before 2009 and decreased in 2011.
The results show a good agreement between the two methods for gasoline passenger cars' HC emission for all IVE subsectors and technology classes.

In addition, except BMI subsector, in all other subsectors, it is seen that production scale has large impact on the efficiency of the firm and also the average efficiency of medium- and large-scale firms in each subsector is higher than the average efficiency of small-scale firms of same subsector.
Also, except BMI subsector, in all other subsectors, it is seen that production scale has a large impact on the efficiency of the firm and also the average efficiency of medium- and large-scale firms in each subsector is higher than the average efficiency of small-scale firms of same subsector.
The coefficients obtained from the subsectors, except for OCP and MP subsectors in which the sign of the capital is negative, in other subsectors is consistent with expectations.
