我国《反垄断法》和《反价格垄断规定》都对市场中的区别定价行为进行了规制。但从法律条文的表述中不难发现,这些规定比较笼统,既没有区分最终产品市场和中间品市场,也没有考虑到不同市场结构下定价均衡的变化及其对社会总福利的影响。本文从反垄断经济学的角度,对不同市场结构下纵向产业链中中间品不同定价方式的均衡进行了分析,并根据理论分析对中间品区别定价的影响加以细分,以期对相应的法律条款加以细化,为规制机构合理规制相关产业提供了一定的理论依据。
China’s “Anti-Monopoly Law” and “Anti-Price Monopoly Regulations” all regulate the differential pricing in the market. However, it is not difficult to find out from the formulation of legal provisions that these provisions are more general and do not distinguish between the final product market and the intermediate product market. They also do not take into account the changes in the pricing equilibrium under different market structures and their impact on the overall social welfare. In this paper, from the perspective of antitrust economics, this paper analyzes the equilibrium of different pricing methods of intermediate products in the vertical industrial chain under different market structures and subdivides the influence of different pricing methods on the intermediate products according to the theoretical analysis, with a view to corresponding legal provisions To refine, provide a theoretical basis for the regulatory agencies to properly regulate the related industries.
