Agricultural production structure,market conditions and farmers’nutritional intake in rural China

Nutrition poverty alleviation is an effective measure to improve the nutritional status of economically disadvantaged individuals,fundamentally improving their health and reducing poverty.Based on the Entitlement Theory and using the China Health and Nutrition Survey(CHNS)data,this paper examines the relationship between farmers’nutritional intake,production structure and regional market conditions.Results show that farmers with diversified production have better nutritional intake than those who specialize.Furthermore,the correlation between regional market conditions and nutritional intake varies between economically disadvantaged and non-economically disadvantaged households.Market conditions significantly influence the carbohydrate and fat intake of economically disadvantaged households and are positively associated with the dietary structure and nutritional intake of non-economically disadvantaged ones.Moreover,income is positively correlated with the nutritional intake of non-economically disadvantaged households but not with economically disadvantaged ones.

Asset Smoothing and Consumption Smoothing:Disaster-coping Strategies in Noncontiguous and Contiguous DestituteAreas

Do households sell assets in order to smooth consumption?The empirical evidence is mixed.Using household-and village-level data in the context of China's poverty alleviation policy,we analyze the relationship between climate shocks and household coping behaviors from the perspective of whether coping strategies to deal with weather shocks are sensitive to the contiguity of destitute areas.Our results indicate that,unlike households living in noncontiguous destitute areas,households struck by weather shocks in contiguous destitute areas tended not to reduce or liquidate assets.To overcome weather shocks,households in contiguous destitute areas instead reduced household consumption,such as food consumption and increased nonfarm working hours.Our findings point to the possibility that the implicit assumption of consumption smoothing coupled with a failure to incorporate explicitly the factor of contiguous regions has led to seemingly divergent findings in the literature regarding consumption smoothing.

可追溯猪肉原产地属性与可追溯信息属性的消费者偏好分析

本文以中国江苏省无锡市110位消费者为样本,采用真实选择实验的方法,借助随机参数与潜在类别模型研究了消费者对可追溯猪肉属性及其层次的偏好。结果表明,消费者对可追溯信息真实性的政府认证属性支付意愿最高,对原产地属性的支付意愿高于对可追溯信息属性的支付意愿,且追溯到屠宰加工环节的可追溯信息属性与本地产属性之间存在替代关系,与外地产属性之间存在互补关系。因此,尽管消费者群体存在异质性,但不同类别消费者对可追溯猪肉的本地产属性均具有一定的支付意愿。故在中国可追溯食品市场建设初期,在可追溯食品属性体系中设置原产地属性具有积极意义。

消费者对可追溯食品属性的偏好和支付意愿:猪肉的案例

本文基于中国猪肉全程供应链体系的主要环节的安全风险,界定了猪肉的可追溯信息,并以商务部肉菜流通追溯体系建设七个试点城市的1489个消费者为调查对象,运用选择实验(choice experiment)方法,借助混合Logit(mixedLogit)模型和潜在类别模型(1atentclassmodeling)研究了消费者对可追溯猪肉属性的偏好及支付意愿。研究结论显示,不同类别的消费者对可追溯猪肉属性的偏好与支付意愿存在较大差异。消费者对质量认证属性最为重视,其次为外观和可追溯信息;相对于政府认证,消费者更偏好于国内第三方机构认证;性别、年龄、受教育程度与收入水平显著影响消费者对可追溯猪肉属性的偏好。
