In this paper, we established a bargaining model of eco-compensation standards for inter-provincial water source protection under finite and infinite bargaining conditions by applying the Rubinstein & Stahl bargaining model after analyzing the problems in the existing basin eco-compensation calculation methods. The established model was applied to the Yuqiao Reservoir to analyze the eco-compensation standards of Tianjin Municipality for Hebei Province in terms of compensation regions. We discussed the impacts of bidding order variation and discount factor variation on the compensation standards. The results showed that the eco-compensation standards for Yuqiao Reservoir basin, the region around Panjiakou-Daheiting reservoirs and along Luanhe-Tianjin water transfer project, and the main water source region Chengde City were respectively between 167 to 1596 million RMB, 30 to 1149 million RMB, and 849 to 8537 million RMB. The impact factor analysis demonstrated that, in the finite bargaining, the inter-provincial eco-compensation standard was related to the discount factor ?, the duration of the biding stage T, and the last bidder; in the infinite bargaining, the standard was related to the discount factor ? and the first bidder.
