兼业如何影响农户对绿肥环境属性的偏好

The Affects of Concurrent Business to Farmer’ s Preference for Green Manure Environmental Attributes

    摘要
  • 摘要: 绿肥是固碳释氧、提高耕地质量的重要绿色农业技术之一，而农户兼业是否影响其对绿肥环境属性的偏好及异质性尚不明确。基于此，本文运用选择实验法与随机参数Logit模型对冀鲁豫皖四省小农户进行实证检验。结果表明：（1）兼业对农户施用绿肥具有显著负向影响。（2）低兼业农户（纯农户与一兼农户）对绿肥的支付意愿显著高于高兼业农户（二兼农户与非农户）。其中，纯农户支付意愿为185.627元/（667 m2·a），一兼农户支付意愿为270.659元/（667 m2·a），二兼农户支付意愿为119.461元/（667 m2·a），非农户支付意愿为140.875元/（667 m2·a）。（3）不同类型的农户对绿肥环境属性及方案的选择存在明显差异：纯农户偏好改善水质、提高耕地质量与肥力、改善空气质量、减少自然灾害的环境属性；一兼农户偏好改善水质、提高耕地质量与肥力的环境属性；二兼农户偏好改善水质、略有提高空气质量的环境属性；非农户则偏好改善空气质量的环境属性。据此，提出建议：（1）针对兼业程度不同的农户制定不同的政策；（2）推广社会化服务；（3）加大农村教育投入，完善农村教育体系；（4）通过网络、广播等拓宽信息渠道提升农户对环境感知能力及对绿肥认知水平。

     

    Abstract: Green manure is one of the important green agricultural technologies to fix carbon and release oxygen and improve the quality of cultivated land. It is still unclear whether farmers’ concurrent work will affect their preference and heterogeneity of the environmental attributes of green manure. Based on this, this paper uses the Choice experiment method and Random parameter Logit model to conduct empirical tests on small farmers in the four provinces of Hebei, Shandong, Henan and Anhui. The results show that: （1） Concurrent Business has a significant negative impact on farmers’ application of green manure. （2） The willingness to pay for green manure of low concurrent farmers (pure farmers and type Ⅰ farmers) is significantly higher than that of high concurrent farmers (type Ⅱ farmers and non-farmers). Among them, the willingness to pay of pure farmers is 185.627 yuan/（667 m2·a）, the willingness to pay of the type Ⅰ farmers is 270.659 yuan/（667 m2·a）, the willingness to pay of the type Ⅱ farmers is 119.461 yuan/（667 m2·a）, and the willingness to pay of pure farmers is 140.875 yuan/（667 m2·a）. （3） Different types of farmers have obvious differences in the environmental attributes and options of green manure. The pure farmers prefer to improve water quality, improve the quality and fertility of cultivated land, improve air quality, and reduce the environmental attributes of natural disasters. The type Ⅰ farmers prefer to improve water quality and improve environmental attributes of cultivated land quality and fertility. The type Ⅱ farmers prefer environmental attributes that improve water quality and slightly improve air quality. The non-farmers prefer environmental attributes that improve air quality. Accordingly, it propose that: （1） formulate different policies for farmers with different degrees of part-time work; （2） promote social services; （3） increase investment in rural education and improve the rural education system; （4） broaden information channels through the Internet and radio to enhance farmers’ perception of the environment and their awareness of green fertilizer.
