Title Research on the Contract of Supply Chain Based on Network Externality
Abstract Based on the network externalities make the corresponding needs profound assumptions, and separately the wholesale price contract, repurchase price contract, quantity discount contract and revenue sharing contract were analyzed under the network externality conditions, and to construct the corresponding profit function model, and the use of decentralized decision-making, implicit function, find the retailer's optimal order quantity containing market price p’s q-algebra, and in accordance with the optimal order quantity, *q-algebra obtained in order to obtain the maximum benefits of the retailer's market choose optimal price, and then substituted into the supplier's profit function derived unknown suppliers containing the decision variables profit function, and suppliers get the most profits of the decision variables are related. Keywords : network externalities; supply chain contract; buy back contract；wholesale price contract；decentralized decision；lease revenue sharing; quantity discount contract

1 引言 20世纪末开始有广大学者研究供应链以及供应链契约，网络外部性是一新兴的经济名词，目前是一热门研究方向。通过阅读大量文献，网络查询，发现研究网络外部性、供应链契约的学者很多，但是却没有将其综合研究，并提出网络外部性对供应链契约是否存在影响，并进行合理的假设，验证及分析。因此，本文将供应链契约基于网络外部性进行研究。
