【Abstract】 For the problem that resident actual purchasing power is lower than potential purchasing power at the present in our country,according to commodity subsidy policies of our country,a differential mathematical model was established for different market conditions.There were a detailed analysis and discussion on this model by using the stability and qualitative theory of ordinary differential equations,and then from the economic point,the economic significances of the main results were discussed.Finally,some theoretical basis for the commodity subsidy policies for government were provided.更多还原
