农户禀赋、社会化服务对水稻化肥利用效率的影响OA

In order to explore the effect of farmers' endowment on chemical fertilizer use efficiency,based on survey data from 378 rice farmers in Suihua City,Heilongjiang Province,this study used the stochastic frontier analysis method to measure the efficiency of rice fertilizer use,constructed a Tobit regression model and a mediating effect test model to empirically analyze the impact of farmers' endowment on fertilizer use efficiency of rice and its mechanism of action.The results showed that the overall level of fertilizer use efficiency of rice among the sample farmers was high,but there was still room for improvement.Farmers' endowment significantly positively affected fertilizer use efficiency of rice,with family population among human endowment,average area of the block among natural endowment,household income natural endowment,social status,degree of organization and information channel among social endowment having significant positive impacts on fertilizer use efficiency.The area of cultivated land in natural endowment significantly negatively affected fertilizer use efficiency.Agricultural socialized services played a masking role in the impact of farmers' endowment on fertilizer use efficiency of rice.It is recommended to improve the level of farmers' endowment,promote the development of agricultural socialized services and improve the awareness and ability of farmers to reduce fertilizer application,in order to promote the efficiency of fertilizer use of rice.
