【摘要】 本文基于选择实验方法,构建了技术特征如何影响其接受程度的定量分析方法,并对施肥减量化技术在沿南四湖地区被农户接受的情况进行了案例分析。研究结果表明,某技术产量越高、政府补贴越多则被农户接受的概率越高,而某技术施肥量越大、一季作物施肥所需次数越多,则被农户接受的概率越低。关于技术特征变化的接受意愿,农户对化肥施用量增加1%、粮食减产1%、一季农作物所需施肥次数增加1次的接受意愿分别为4.6元、13.2元、74.4元。根据模型测算,测土配方技术被调研农户接受的概率为0.75;采用测土配方技术给农户带来的经济福利增加以货币度量为226.75元。更多还原

【Abstract】 The paper built a quantitative analysis method was built to analysis how the technological characteristics affected its adoption by farm household based on choice experiment method,and a case study was carried out on the farm household willingness to adopt fertilizer reducing technologies in the region around Nansihu Lake.It was shown that,the higher the yield,the more the subsidy from government,the adoption probability of the technology was higher,while the more the fertilizer needed,the more the fertilizing times,the probability was lower.As for the willingness to adopt for the change of technologies characteristics,it was 4.6 Yuan for reducing fertilizer amount by 1percent,13.2 Yuan for reducing grain yield by 1 percent,and 74.4 Yuan for increasing the fertilizing times by one time.It was predicted that the balanced fertilizer technology was adopted with the probability 0.75,which would increase farm household economic welfare with 226.75 Yuan in monetary.更多还原
