It also studies the effect of food subsidies on farmers' behavior of growing grain. Farmers' behavior of growing grain is a helpless choice under many constraints,including not only economic returns,but also moral sentiments,political and social factors. From yield,quality and price,government should rely on science and technology to give full play to the functions of government guidance and supervision,and enhance the enthusiasm of farmers for growing grain,to increase food production and ensure food security.展开更多

We make an empirical analysis of the factors influencing farmers' rabbit demand,and put forth the recommendations for farmers' rabbit breeds usage and to improve the promotion of new varieties of rabbits.展开更多

The lower the consumption level or the lower the income level,the stronger the inhibitory effect will be. Uncertainty of expenditure also has a significant inhibitory effect on the consumption of migrant workers. Promoting urbanization of migrant workers and accelerating the reform of the household registration system can reduce the uncertainty risks faced by migrant workers,so as to raise the consumption expectation of migrant workers,release the consumption potential of migrant workers,and improve the living standards of migrant workers.展开更多

文摘Based on the substitutability of economic activities,by comparing the profit margin of farmers' planting of food crops and non-food crops,grain growing and breeding,as well as the daily return of grain growing and working outside during 2001-2013,this paper points out that the comparative income from farmers' behavior of growing grain is not absolutely low,and the income from growing grain is higher than from breeding pigs.
