Recognizing response of economic variables consciously and based on scientific theories results in intelligent decision making. In the past years, Iran has been considered as an agricultural section and particularly wheat has been considered as a strategic product in the upstream documents such as Iran 20- year vision plan and the Five-Year Economic Development Program rules. So, in this paper, Phillips-Perron, Johanssen, impulse response function, variance decomposition and vector autoregressive model are used following studying response of wheat and important effective variables in this part. The results indicate that response of wheat production to shocks applied by variables of added value in agricultural division and wheat cultivation area is positive, increasing and the standard deviation which has been created in production of wheat in the first period has been explained completely by wheat production
