Cooperatives are increasingly advocated as a means to improve incomes, livelihoods and the sustainability of smallholder farmers. This study analyzes the impact of commercial vegetable cooperative membership on smallholder agricultural performance in Cambodia. Institutional heterogeneities are considered across cooperatives and various econometric techniques are used to control for potential selection bias. The impacts of horticulture on agricultural outcomes are also analyzed. The results indicate that membership of commercial vegetable cooperatives has so far had no effect on agricultural incomes or the value or amounts of agricultural inputs. However, results indicate that membership has affected technology choice, access to credit services and information transmission through technological training. Additionally, there is evidence that horticulture, as a component of overall agricultural diversification, can augment farm income. The results suggest that much of the benefit of cooperative membership stems from the cooperative's provision of services, which might not be easily inferred from measures of member incomes.

农业合作社对柬埔寨小农生计和农业绩效的影响

越来越多地提倡将合作社作为提高小农收入、生计和可持续性的手段。本研究分析了商业蔬菜合作社成员资格对柬埔寨小农农业绩效的影响。跨合作社考虑了制度异质性，并使用各种计量经济学技术来控制潜在的选择偏差。还分析了园艺对农业成果的影响。结果表明，迄今为止，商业蔬菜合作社的成员资格对农业收入或农业投入的价值或数量没有影响。然而，结果表明会员资格影响了技术选择、信贷服务的获取和通过技术培训的信息传输。此外，有证据表明，园艺作为整体农业多样化的一个组成部分，可以增加农业收入。结果表明，合作社成员资格的大部分好处源于合作社提供的服务，这可能不容易从成员收入的衡量标准中推断出来。
