SUPPLIER INNOVATION IN THE PRESENCE OF BUYER POWER
分析了零售商买方势力如何影响供应商在产品质量和品种上的创新投入，发现买方势力增强会促使供应商增加品种和提升质量，前提是需求弹性不太大。
Abstract This article analyzes the impact of retailer buyer power on a supplier's incentive to conduct innovation, with a focus on the supplier's investment in product variety and quality improvement. The analysis shows that an increase in buyer power, manifested through either a weakening of the supplier's bargaining position or a strengthening of a large retailer's bargaining power, leads to greater product variety and higher quality if the elasticity of demand is not too large. Increased buyer power, manifested through a strengthening of a large retailer's bargaining position, stimulates the supplier to invest more in quality improvement.
