芝加哥学派从经济的角度分析搭售在质量保证、产品风险分担等方面的合理性,但并未动摇传统的搭售理论。本文指出搭售可能限制竞争市场的公平交易,逃避价格管制,所以仍有规避的必要,但可在适用合理性原则的基础上对搭售行为的豁免情形予以规定。 The Chicago School analyzed the rationality of tying sales in terms of quality assurance and product risk sharing from an economic point of view, but did not shake the traditional tying theory. This article points out that the tie-in may limit fair competition in the competitive market and avoid price control. Therefore, there is still a need to avoid it. However, the exemption of tie-in may be regulated on the basis of the principle of rationality.
