Abstract: According to supply chain benefit coordination problem, it introduced members’ participation and contribution factor for simulating this phenomenon. Moreover,it put forward some mainly driving factors including knowledge sharing cognition, technology gap, the economy and geography space, spill risk control and spill achievements’ compensation. Shapley amendment model and expert′s graded approach were used to make combination of fuzzy decision analysis. It simulated three members of the supply chain enterprise and calculated each members’ participation and the difference of knowledge spillover effect and found that knowledge sharing cognitive factors and spill achievements’ compensation factors had a larger effect on the whole supply chain enterprises’ benefit coordination. Finally, it pointed out the rationality of the correction model and the result shows that the quantitative knowledge spillovers is a key problem, also needs corresponding compensation mechanism research.
