In this study, the hypothesis that there is a long-term relationship between agricultural growth and other economic sectors growth is tested for the case of Iran, using autoregressive distributed lag model (ARDL) and variance decomposition analysis also. The time series data consists of data for the period 1959-2010. The results indicate that the long run relationship exists when the variables gross domestic product (Y), industrial value added (IN), agricultural value added (AG), services value added (SS) and oil and gas value added (O and S) remain to be dependent variables. The long run elasticity also shows that one percent increase in value added of IN, AG, SS and Oil and Gas, will cause the gross domestic product to increase by 0.216, 0.091, 0.431 and 0.156 percent respectively.]]>Babatunde, R.O.,200813541Chebbi, H.E.,201026378Craigwell, R., D.
