Abstract: In recent years, China’s anti-monopoly policy has taken action in the after-sales market. However, there are still many theoretical and policy difficulties in the implementation of the anti-monopoly policy in the after-sales market. The theoretical difficulty is how to judge whether the manufacturer has market dominance in the after-sales market and abuses its market dominance, as well as how to define in the related after-sales market. The practical difficulty is whether the implementation of the anti-monopoly policy in the after-sales market will damage the industry performance in the context of the state strongly encouraging the manufacturing industry to transform into services. On the basis of summarizing the different views and policy opinions of anti-monopoly in the after-sales market in the West, this paper analyzes the difficulties in the implementation of anti-monopoly policies in China’s after-sales market and puts forward the opinion of constructing an anti-monopoly policy system in China’s after-sales market.

Key words: after-sales market; anti-monopoly; policy system
