Abstract: Purpose/Significance The vigorous development of the platform economy under the new retailing model has brought far-reaching impacts on market sellers, consumers, e-commerce platforms and other upstream and downstream market participants. Meanwhile, such development not only strengthens the information superiority of e-commerce platforms over the upstream sellers, exacerbating information asymmetries but also makes the channel operating structure more complex, resulting in the emergence of co-opetitive platform supply chains. Design/Methodology Focusing on the new business form of the platform economy, this paper systematically classifies the existing literature and summarizes the research characteristics from the perspectives of information sharing, channel co-opetition and operation strategy in the e-commerce platform, aiming to shed light on the inherent relations among these research themes. Conclusions/Findings Furthermore, this paper point out future research direction, new hotspots and difficulties of operation and management under the platform economy, providing a reference and basis for domestic and foreign scholars to carry out related research.
