Investigating the Cause of Reducing Iran Country Share in Global Cotton Production Using of Parametric Method
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 6
Abstract
Cotton is one of the important industrial plants and supplies good part of oil and fiber needed. In this study, using data collected in time period 2001-2011 using, Systemic method of ordinary least squares estimator (OLS), to estimate the supply equation and investigate the causes of the decline share Iran Country in global cotton production, in the form of a single equation regression models were discussed . The results of the estimation of the supply function shown the cotton price variables (PC =+2.58), the price of synthetic fibers (Py =+0.11), per capital income (IN=+1.47), per capita demand of cotton a year ago (Xdt-1=+0.14) on cotton production in the years has a positive effect. Based on the results of the main reasons for the decline in value of the variable of cotton imports this year (IMt-1=-0.15) and the cost of producing cotton (CPt-1=-0.45), Which has a negative impact on cotton production in the country. Variable amounts of cotton imports years ago (IMt-1=-0.15) and the cost of producing cotton (CPt-1=-0.45), has a negative impact on cotton production in the country. In general, the reduction of tariffs on cotton and entry More than need this product to country and increase the cost of production from the major causes of failure of cotton production in the country is the most important reason to reduce the incentive for manufacturers of produce cotton.
