农户对夏玉米品种性状属性的支付意愿研究——基于选择实验的分析

基于河南和山东农户调研数据,采用选择实验方法,应用随机参数模型与潜在类别模型分析农户对夏玉米品种的生育期、与干旱相关的产量特征、籽粒品质及穗位整齐度性状属性的偏好与支付意愿。研究表明,农户对玉米品种性状偏好具有异质性,根据这种异质性可以将农户分为穗齐偏好农户和产量稳定偏好农户,但追求产量目标的农户少于追求轻简目标的农户;农户对玉米品种的穗位整齐度的支付意愿最高,其次为玉米的产量特征和生育期,对玉米籽粒的品质属性支付意愿最低。因此,培育耐旱稳产型、适宜机械化操作的穗齐型且生育期较短的"轻简型"玉米品种是中国玉米育种的主要方向。

Farmers'Willingness to Pay for Summer Maize Varieties Traits:Based on Choice Experiments

Based on the survey data of household demand in Henan and Shandong,using choice experiment method,applying the random parameters model and latent class model,the paper analyze farmers'willingness to pay for summer maize varieties traits which include yield characteristics associated with drought,growth period,grain quality,and spike position.The result shows farmers'willin gness to pay for spike position is highest,followed by yield characteristics associated with drought and the growth period,and the willingness to pay for grain quality of maize was the lowest.Therefore,the main direction of maize breeding in China is to fostering drought-tolerant and stable yield,ear position more neat for mechanization,early-maturing and saving type maize variety.
