Designing an appropriate coordination mechanism for an online shopping service supply chain （OSSSC） is a critical issue of supply chain management in Internet background. Individual rationality and fairness concerns as two attributes are less considered in existing studies but affect the decisions of decisionmakers in reality. In this study， a coordination contract considering above individual attribute is designed for an OSSSC having two competing third party logistics （TPL） companies and a single online store. Firstly， two decision equilibriums of two decision scenarios （the decentralized and centralized） are solved， the comparative study shows that the priceonly contract has some limitations concerning to improve the level of logistics service or the performance of the system； secondly， a coordination contract is designed based on the comparative study. The result shows that coordination contract considering the two attributes mentioned above can achieve the unification of individual and collective rationality， and fair allocation of the system surplus profits based on individual decisions. Finally， numerical experiments are conducted to further verify the effect of the contract and some suggestions are proposed based on above results.
