The development of the mobile Internet has abandoned the nature of the open interconnection network,which makes the chaos of blocking and shielding emerge in an endless stream in the economic field of the Internet platform,which seriously damages the welfare of merchants,consumers,and the platform itself.To this end,the Ministry of Industry and Information Technology launched the Internet transformation and rectification campaign in July 2021,aiming to strengthen the circulation of users,data,technology and other elements between different platforms,in order to achieve "ecological connectivity" and build an orderly market operation mechanism.Therefore,combining with the ecological exchange ownership shift brought about by the consumers,based on the classic hotelling model,analyses the ecological system of the platform economy within the influence of different participants' welfare,found that ecological exchange can effectively promote the growth of businesses and consumers welfare,after running stable platform,ecological communication also can promote platform corporate earnings growth,However,in the early stage of operation,due to the high fixed cost,ecological interconnection will reduce the revenue of platform enterprises.Therefore,it is suggested that the government should strengthen the supervision of unfair competition,promote the competition concept of winwin cooperation at the enterprise level,guide the flow of consumers at the user level,and finally promote the substantive construction of the operation mode of ecological interconnection.
