Abstract: In the context of the present increasingly severe market competition on products, the aftermarket monopoly has become an important operation mode for many manufacturers. The researches on the aftermarket monopoly have been carried since early in the 1980s and 1990s in foreign countries, and abundant literatures have been produced. The major studies focus on the meaning of aftermarket, the causes of aftermarket monopoly, the motivation of aftermarket monopoly, the pricing of aftermarket monopoly, the efficiency of aftermarket monopoly, and the controversy over antitrust policies. Although China recently has carried out antitrust policy against the automotive aftermarket, no theoretic basis has been really found for the implementation of antitrust policy in the aftermarket. Therefore, there are certain theoretic and practical difficulties to be solved for the implementation of the aftermarket antitrust policy in China.

Key words: aftermarket; monopoly; policy controversy
