This paper proposes a cooperation strategy based on the bilateral effort “cost sharing + revenue sharing” contract for truck-flight supply chains. This strategy considers a truck-flight supply chain that includes a single flight and a single transport company， and investigates the freight， bilateral efforts and profits of the centralized and the decentralized decision-makings. Our investigation finds out that （1） the levels of bilateral efforts and profits of the decentralized decision-making are lower than those of the centralized decision-making； （2） the bilateral efforts under the combined contract of “cost sharing + revenue sharing” can reach the level of the centralized decision-making， and realize the coordination of the truck-flight supply chain； （3） with certain conditions， the combination contract can make Pareto improvement on the revenues of all parties in the truck-flight supply chain. Finally， the simulation verifies the effectiveness of the combination contract， and the sensitivities of the parameters are analyzed.
