The growth of "total productivity of production factors (TFP)" of the housing sector during the period of ‏2021-1986‏‏‏‏‏‏ , based on the techniques of "econometrics" and "envelopment analysis of data", into four components; Technological progress, change in technical efficiency, scale effects and specific efficiency were analyzed. The average value of these components respectively is 1.47 ; 0.53 ; 1.52; 0.15% and the average TFP growth is 3.67%. In this connection, technical efficiency, effective tensions and income share of production factors have also been calculated; The results show that the housing sector works close to technical efficiency and the trend of inefficiency is decreasing, the average effective elasticity of labor force and capital stock are 1.06 and 0.92 respectively, and the income share of these two respectively is 0.51 and 0.49 percent. The return to scale is also greater than one and increasing. However, production units are not able to improve the share of technical efficiency change in TFP growth. The average of other drivers is also positive, but due to the lack of synergy between technological progress and scale effects, and despite the smallness of allocation efficiency; have not had an acceptable impact on productivity growth.
