摘要
运用选择实验法研究豫、冀、鲁、皖4省1058份种麦小农户对种植绿肥环境属性的支付偏好,结合随机参数Logit模型对小农户资本禀赋、环境变化感知的异质性进行了实证分析与检验,对绿肥不同环境属性的支付意愿进行了分析。结果显示:在农户禀赋中,家庭农业劳动力数量、人均收入水平、与亲友交流频繁程度、文化程度对小农户绿肥环境属性的支付意愿有积极影响;在环境变化感知中,担心小麦产量受到环境恶化影响的小农户在支付意愿上更强;在资本禀赋和环境变化感知因素的影响下,农户对豆科绿肥环境属性的支付意愿显著提高,其中,对耕地质量与肥力提高属性的支付意愿最高,对耕地质量与肥力略有提高属性的支付意愿最低。
Based on the choice experiment survey from 1058 wheat-smallholders in four provinces of Henan,Hebei,Anhui and Shandong,the smallholders’payment preferences on green manure’s environmental attributes were analyzed.Meanwhile,random parameter logit models were used to analyze the heterogeneity of smallholders’capital endowments and perception of environmental changes and explore the marginal willingness to pay for different environmental attributes of green manure.The results show that among the endowment of smallholders,the number of family agricultural labor,per capita income level,frequency of communication with relatives and friends,and education level have a positive impact on the willingness of smallholders to pay for the environmental attributes of green manure;in terms of the perception of environmental changes,smallholders who are concerned that wheat production will be affected by environmental degradation are more willing to pay;under the influence of capital endowments and environmental change perception factors,farmers’willingness to pay for the environmental attributes of leguminous green manure has increased significantly with highest willingness to pay for cultivated land quality and fertility improvement attributes and lowest willingness to pay for attributes of slightly improved land quality and fertility.
