CER | 合作社成员资格对农业技术采用的影响【转】

摘要简单翻译：

农民合作社可以促进农业生产中的技术采用,从而增加作物生产力和农民收入。然而,关于合作社如何以及在何种程度上促进技术采用扩展的经验证据,即农民从各种农业技术中采用的技术数量,仍然不清楚。为了解决这一知识差距,我们使用从中国四川省413个农户收集的横断面数据,研究合作社成员对技术采用扩展的影响。我们使用倾向分数匹配与工具变量方法相结合,解决与自愿合作会员选择相关的样本选择偏差。统计结果表明,在考虑所有13种被调查技术时,合作社成员对技术采用扩展有积极影响。然而,对采用生产和收获后技术的单独分析表明,合作社成员对采用的生产技术数量影响不大,但它大大增加了采用的收获后技术。这些实证发现符合新的制度经济学理论和我们在当地的观察。

Abstract:

Farmer cooperatives may promote technology adoption in agricultural production, which, in turn, increases crop productivity and farmers' income. However, empirical evidence of how and to what extent cooperatives facilitate the technology adoption extensity, defined as the number of technologies adopted by a farmer from a wide range of agricultural technologies, remains unclear. To address this knowledge gap, we examine the impact of cooperative membership on the technology adoption extensity using cross-sectional data collected from 413 farm households in Sichuan province of China. We use propensity score matching combined with an instrumental variable approach to address the sample selection bias associated with voluntary cooperative membership choice. The statistical results suggest that cooperative membership has a positive effect on the technology adoption extensity when all 13 surveyed technologies are considered. However, the separate analyses on the adoption of production and post-harvest technologies reveal that cooperative membership has an insignificant impact on the number of adopted production technologies, but it significantly increases the number of post-harvest technologies adopted. These empirical findings are in line with the new institutional economics theories and our observations on the ground.
