Technology Training, Buyer-Supplier Relationship, and Quality Upgrading in an Agricultural Supply Chain
通过随机实验，研究了技术培训（特别是农民与出口商共同培训）如何通过改善买卖双方关系促进技术采纳和农产品质量升级。
Abstract This paper examines the impacts of technology training and buyer-supplier relationship on technology adoption and quality upgrading. We randomly varied subjects of each training group across farmer-exporter clusters—farmers, exporters, both, or none—and provided training on Good Agricultural Practices (GAP). We find that training farmers enhances technology adoption and quality upgrading. Yet, the effects are much stronger when farmers and exporters are trained together. We document a plausible mechanism to explain this finding: joint training improves buyer-supplier relationship, which facilitates contract trade between farmers and exporters. We find no effect of GAP certification eligibility on technology adoption.
