The evolution of e-commerce drives suppliers to develop online direct selling channels to encroach on the retail market, in addition to the traditional distribution channels through the retailer. A systematic literature review (SLR) approach is adopted in this paper to review the existing studies using theoretical models to capture supplier encroachment behavior, as well as the related industry practice phenomena and strategic factors in the supply chain. We present the major research streams according to the selected encroachment literature from two aspects: channel conflict and coordination as well as information structures. We also generalize the significant practical strategies and strategic factors that have been investigated, combined with supplier encroachment, such as investment and spillover effects, the retailer’s store brand introduction, strategic inventory, and contract mechanism designs. More importantly, we summarize the classical theoretical models which include the basic models, the signaling game model, and the Hotelling model, and these have been widely used by scholars to capture the supplier’s encroachment behavior. Finally, we provide several suggestions which may be valuable for researchers to identify future potential research directions.

电子商务时代供应链中的供应商侵占：系统文献综述

电子商务的发展促使供应商在通过零售商的传统分销渠道之外，开发在线直销渠道以蚕食零售市场。本文采用系统文献综述（SLR）方法回顾现有研究，使用理论模型来捕捉供应商侵占行为，以及相关的行业实践现象和供应链中的战略因素。我们根据选定的侵占文献从两个方面介绍了主要的研究流：渠道冲突和协调以及信息结构。我们还概括了已调查的重要实践策略和战略因素，并结合供应商的侵占，例如投资和溢出效应，零售商的店铺品牌引进、战略库存、契约机制设计。更重要的是，我们总结了经典的理论模型，包括基本模型、信号博弈模型和霍特林模型，这些模型已被学者广泛用于捕捉供应商的侵占行为。最后，我们提供了一些可能对研究人员确定未来潜在研究方向有价值的建议。
