摘要 Abstract of the Paper	This paper examines competition in the repair service market between manufacturers and independent aftermarket service organizations (ISOs). The manufacturer produces a product that can be broken with some probability after usage and consumers can deliver the broken units to either the manufacturer or the ISOs, while the manufacturer provides a better quality of service. In equilibrium, the aftermarket can be either covered or uncovered, depending on whether all broken units are repaired. We highlight two effects caused by the ISOs’ quality improvement: a quality-improving effect in the product market and an aftermarket competition effect. We find that, under a covered aftermarket, the manufacturer’s output will increase due to a dominating quality-improving effect, while the profit and consumer surplus may decrease. By contrast, under an uncovered aftermarket, an increase in the ISOs’ quality will reduce the manufacturer’s output and profit but benefit the consumers due to lower prices.
