Abstract: A reasonable profit distribution mechanism is the key to the stable development of the coal supply chain. This paper collects the data of three enterprises in the coal production, transportation and marketing supply chain of Shanxi Province. Based on the analysis of the cost-benefit composition of the individual and cooperative operation of each link subject, the Shapley value method is used to calculate the profit distribution of each subject in the coal production, transportation and marketing supply chain, and the following conclusions are obtained: 1) The profit of coal production, transportation and sales enterprises in cooperative operation increased by 6.34%, 17.88% and 0.56% respectively compared with that in separate operation, and the overall income increased by 6.4%. In the cooperative state, the overall income is greater than the sum of the income of each enterprise when operating independently, and the income of each link enterprise is greater than the income obtained when operating independently. 2) When operating independently, the revenues of production, transportation and sales enterprises account for 48.69%, 17.52% and 33.80% respectively. The reasonable profit distribution plan of the production, transportation and sales supply chain calculated by the Shapley value method are 48.65%, 19.41% and 31.94% respectively. 3) Contributions to the production, transportation and sales supply chain from large to small are coal production enterprise, sales enterprise and transportation enterprise.
