Abstract:Agricultural subsidy has attracted more and more attention. Th is paper captures the eff ects of subsidy (including area subsidy and price subsidy) on the total sown areas of crops based on the assumption that subsidy has both stimulating eff ects and inhibiting eff ects. Diff erent from the prior studies, this paper considers the impacts of the farmland constraint and demand elasticity and some interesting conclusions are achieved. Firstly, a stimulating eff ect increases crop sown areas while an inhibiting eff ect reduces them. Secondly, the output effi ciency of farmland as well as the demand elasticity has a major impact on the government subsidy. Besides, the capacity constraint makes thing diff erence and the government should choose between the areas subsidy and price subsidy under diff erent conditions. Finally, this paper off ers an empirical test on the conclusions by adopting the Chinese agricultural statistical data.
