本文考察了买方-供应商关系对企业绩效的重要性。我们开发了一个模型，在该模型中，公司外包任务并寻找供应商。较低的搜索和外包成本导致公司搜索更多并找到更好的供应商，这反过来又降低了边际成本。我们通过利用日本一条高铁线路的开通来检验这一理论，这条线路降低了乘客出行成本，但运输成本保持不变。使用关于公司买方-卖方联系的详尽数据集，我们发现与模型一致的公司业绩以及买方-卖方联系的创建都有显著的改善。
This paper examines the importance of buyer-supplier relationships for firm performance. We develop a model in which firms outsource tasks and search for suppliers. Lower search and outsourcing costs lead firms to search more and find better suppliers, which in turn drives down marginal costs. We test the theory by exploiting the opening of a high-speed train line in Japan, which lowered the cost of passenger travel but left shipping costs unchanged. Using an exhaustive data set on firms' buyer-seller linkages, we find significant improvements in firm performance as well as creation of buyer-seller links, consistent with the model.
