Treating platforms as a fixed business model makes it difficult to form a joint force in academ-ic research,and also delays the upcoming platform regulation.Platforms have evolved from information-storage intermediaries in Web 1.0 to information-exchange intermediaries in Web 2.0,and to business-aggregation intermediaries in Internet Ecosystem.Such an evolution not only changes the definition of platforms,but also causes expansions and variations of monopoly conduct,i.e.the expansions of rele-vant markets within Web 2.0 and Internet Ecosystem,and the variations of the relations between plat-forms and non-competitors and between platforms and business operators.While the traditional anti-mo-nopoly mechanism still maintains its effectiveness in regulating inter-platform monopoly conduct when in-tegrating an evolutional view on platform models,it reaches its limit in coping with the variations of rela-tions between platforms and business operators,namely the abuse by platforms of their organizing func-tion to strengthen the profit-running function.To bridge the gaps in the anti-monopoly mechanism,it is necessary to adopt categorical regulation based on two platform types,namely to guide and monitor the making of intra-platform rules by big platforms,prohibit super platforms from applying self-preference,and shift the burden of proof to super platforms in cases of predatory acquisitions.
