Estimating provincial Capital Stock in Iran Economy

Investment and capital stock variables are considered as critical data requirements in economic policy making. In this context, having access to the statistics and performance of these variables is regarded as one of the requirements in economic planning. It will be more important especially at levels beyond the national level such as provincial level at which the data are not produced by national institutions responsible for economic statistics. In order to meet this need, in this paper we have tried to calculate the provincial capital stock index and its alternative variables using the capital stock estimation methods. To do that, an approach is introduced and applied to estimate the capital stock variable at provincial level by reviewing the literature of production function,. Also two alternative variables and their related data are suggested for a sample period 2006-2012. The results could be applicable not only in comparative studies and policy making at provincial and regional levels but in quantitative studies in the field of productivity and efficiency, economic growth ,saving and investment and input – output analysis.</span>
