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.

The purpose of this paper is decomposition of total factor productivity (TFP) to technological progress, technical efficiency, allocative efficiency, scale effects in Iran’s manufacturing industries. For this, a stochastic Frontier production model was estimated for 135 manufacturing industries over the period 1379-1393. The findings showed that technological progress in 21 industrial groups has been grew on average 12 percent annually. In relation to technical efficiency many of technical industries have been weaken in using exist technologies or have been inefficient technically. The third factor findings showed that Iran’s manufacturing industries have been utilized from scale effects. In relation to allocative efficiency, also, all groups have experienced negative growth except Recycle group. In result, among components of total factor productivity, allocative efficiency has been more unfavorable and it refers to in Iran’s economy the resources allocate in unfavorable. On the base of the results, improvement in financing system, increasing in private sector capacitance, improvement in business space are suggested.

The aim of this paper is decomposition of total factor productivity (TFP) growth to four factors technological progress, technical efficiency, allocative efficiency, scale effects in 21 manufacturing industries, using a panel data technique, during 2000-2011.Findings show that the production elasticity related to labor and capital is o.57 and 0.13, respectively and economy of scale is less than unit. Also, results indicate that productivity growth is positive only in 8 industries that include electronics, communications, paper, medical and optical industries. The decomposition reveals that, TP has been the main driving force of productivity growth- especially in chemical, non-metal mineral, primary metal, motor vehicles, trailers and semi-trailers- while negative efficiency changes, allocative efficiency and scales effects observed in certain industries have contributed to reduce average productivity growth.
