摘要
网络平台纵向一体化极具垄断风险,其实质是市场力量的跨界传导即杠杆理论的行为表现。相比于纵向一体化带来的效率福利,其垄断风险更需引起重视,需要反垄断法加以规制。当下世界各国态度有两种:管控与放任。放任模式主要沿袭芝加哥学派的理论,但单一垄断利润定理相对忽视了长期垄断风险,也难以解释平台经济中的零价格市场结构;以“价低质优”作为评判消费者福利的基本标准,相对忽视了竞品的数量和消费者自我选择的权利,并且对消费者偏好预测的困难在平台经济下显现得尤为明显。平台经济时代,杠杆理论所体现的垄断力量传导效应必须得到重视,网络平台纵向一体化必须得到规制。
The vertical integration of network platforms is extremely risky of monopoly,and its essence is the cross-border transmission of market forces,that is,the behavioral manifestation of leverage theory.Compared with the efficiency benefits brought about by vertical integration,its monopoly risk needs more attention and requires the regulation by the anti-monopoly law.At present,there are two attitudes in the countries in the world:control and no control.The no-control model mainly follows the theory of the Chicago school,but the single monopoly profit theorem relatively ignores the long-term monopoly risk,and it is difficult to explain the zero-price market structure in the platform economy.This model takes“low price and high quality”as the basic standard to judge consumer welfare,and it relatively ignores the quantity of competitive products and consumers’right of self selection;and the difficulty of predicting consumers’preferences is particularly obvious under the platform economy.In the era of platform economy,the monopoly power transmission effect embodied by the leverage theory must be paid attention to,and the vertical integration of network platforms must be regulated.
