Abstract: The form of supply chain cooperation affects the engendering mechanism and distribution of cooperation benefits.Therefore,it is necessary to study the distribution of cooperation benefits under different cooperation forms Based on supply chain cooperation between coal and electricity power enterprises,we use the infinite stage bargaining game to model the distribution of cooperation benefits,with the profit allocation factor taken into consideration.This is applicable to cases where one party invests in the other.Further,we employ Shapley Value method and the expectation theory to model the distribution of cooperation benefits according to contribution to cooperation and the tradeoff between risks and rewards.This applies to long-term contracts and strategic cooperation.Our analysis has implications for the distribution mechanism of cooperation benefits between producers and suppliers.

Key words: supply chain cooperation, distribution of cooperation benefits, bargaining game, shapley value risk expectation
