超级市场在许多发展中国家的农粮系统中越来越普遍。虽然最近的研究分析了小农业部门的收入影响，但对生产力和效率的影响几乎没有研究。我们使用元前沿的方法，并结合联合收割机这与倾向评分匹配，以估计在肯尼亚蔬菜农民的治疗效果。参与超市渠道可使农业生产力在元技术比率方面提高45%。我们还发现积极和显着的影响，技术效率和规模效率。因此，超市的扩张为小农场部门的农业增长提供了机会，这对非洲的减贫至关重要。
Supermarkets are gaining ground in agrifood systems of many developing countries. While recent research has analyzed income effects in the small farm sector, impacts on productivity and efficiency have hardly been studied. We use a meta-frontier approach and combine this with propensity score matching to estimate treatment effects among vegetable farmers in Kenya. Participation in supermarket channels increases farm productivity in terms of meta-technology ratios by 45%. We also find positive and significant impacts on technical efficiency and scale efficiency. Supermarket expansion therefore presents opportunities for agricultural growth in the small farm sector, which is crucial for poverty reduction in Africa.
