Rural–urban migrants’ remittance and agricultural pollution in the presence of agricultural dualism

This paper established an open general equilibrium model to study the effect of the change of rural–urban migrants’ remittances rate on agricultural pollution. We found that the increase of migrants’ remittances rate would not influence the output of agricultural pollution factor production sector or the agricultural pollution in the capital specific case; and in the mobile capital case, the increase in the rural–urban migrants’ remittances rate will decrease the output of the agricultural pollution factor production sector and then decrease the agricultural pollution. In addition, we investigated the numerical characteristics of the effects of the change in the rural–urban migrants’ remittances rate on the relevant variables, and we also found that the increase in the migrants’ remittances rate would increase the national income and improve the level of gross national welfare under certain conditions, no matter in the capital specific case or in the mobile capital case.
