The two factors labor and lands can substitute each other but not perfect substitution. The substitute process may affect and lower down the productivity. It could represented by curved PPF, and factor intensive ratio -- real wages / renting rate ratio. Relative product price is significant and affect the wages level, and explicitly affect the wages / renting ratio. The country will subject to factor intensive ratio to determine the substitution in order to max the production value and predict the trade
