Factors Affecting the Calculation of Productivity of Factors of Production Case study: Carbon Co. in Iran

This article has tried to calculate factors affecting the productivity of production in Carbon company of Iran. It has also tried to find out procedures for enhancing the productivity in this unit. The method used for this purpose is based on calculating the productivity of factors of production through parametric methods for the period of 1999-2009. in order to measure the actual productivity in this company the monthly production function data including explanatory variables such as: simple labor force, specialized labor force, as well as existing capital and energy, (to remove no stationary of data), estimation of date based on production function have been used. The results show that, despite fluctuations, the productivity of specialized and non-specialized labor as well as energy have increased at a speedy rate of growth. However, in spite of increasing the existing capital productivity the over all productivity was diminishing dramatically, due to over use of machinery capacities
