Finally,farmers' satisfaction with the supply of public goods for disaster reduction in agriculture in two counties and one district of Hubei Province was evaluated by the model. The results show that farmers are satisfied with the supply of public goods for disaster reduction in agriculture on the whole,but farmers' satisfaction with openness about funds for disaster reduction,supply structure of public goods,work attitude and work efficiency is at a general level. Some suggestions about the four aspects were proposed,such as improving supervisory mechanisms to increase funding transparency,making information channels unblocked to improve the supply efficiency of public goods for disaster reduction,and improving the quality of government workers to increase their work efficiency.展开更多

Taking 515 farmers in 27 villages of Hubei Province as investigation objects,the influence of farmer social capital on cooperative supply willingness of agricultural disaster reduction public goods is explored by Logistic regression model. Research results show that social solidarity,common value concept,social trust and reciprocal content have positive impact on farmer's willingness of cooperative supply,while annual household income,number of agricultural disaster reduction public goods and social network have negative impact on farmer's willingness of cooperative supply.展开更多
