Commercialisation of smallholder agriculture is important for rural economic growth. While previous studies have analysed effects of commercialisation on productivity and income, implications for farm household nutrition have received much less attention. We evaluate the effects of commercialisation on household food security and dietary quality with a special focus on calorie and micronutrient consumption. We also examine transmission channels by looking at the role of income, gender, and possible substitution effects between the consumption of own‐produced and purchased foods. The analysis uses survey data from farm households in Kenya and a control function approach. Generalised propensity scores are employed to estimate continuous treatment effects. Commercialisation significantly improves food security and dietary quality in terms of calorie, zinc and iron consumption. For vitamin A, effects are insignificant. Commercialisation contributes to higher incomes and increased nutrients from purchased foods, but it does not reduce the consumption of nutrients from own‐produced foods. Enhancing market access is important not only for rural economic growth, but also for making smallholder agriculture more nutrition‐sensitive.

小农户的农业商品化与营养

小农农业的商业化对农村经济增长很重要。尽管先前的研究已经分析了商业化对生产率和收入的影响，但对农户家庭营养的影响却很少受到关注。我们评估商业化对家庭粮食安全和饮食质量的影响，并特别关注卡路里和微量营养素的消费。我们还通过考察收入，性别以及自产食品和购买食品的消费之间可能的替代效应的作用来研究传播渠道。分析使用来自肯尼亚农户的调查数据和控制功能方法。使用广义倾向评分来估计连续治疗效果。商业化可大大改善食品安全性和饮食质量，包括卡路里，锌和铁的消耗。对于维生素A，作用微不足道。商业化有助于增加收入和增加购买食品中的营养素，但并不能减少自产食品中营养素的消耗。扩大市场准入不仅对于农村经济增长很重要，对于使小农农业对营养更加敏感也很重要。
