Abstract: In order to study the dual-channel pricing and stochastic inventory problems under different game status of supply chain members, a game model dominated by manufacturers, retailers and equal players is constructed to investigate the impact of stochastic market demand on pricing, inventory and profit. The strategy differences of supply chain with different game status are analyzed, and the optimal response strategy is explored through numerical simulation. The results show that the dominant party has stronger price control and inventory allocation ability to obtain higher income through its position advantage. The manufacturer-led supply chain has stronger channel integration capabilities, and the overall profit of supply chain is higher than that of retailer-led. Both players in the same game status situation can update their strategies according to common market information and competitor strategies, and thus obtain lower inventory risks and channel pricing, but the double marginal effect reduces the benefits of both parties. The higher the fluctuation of market demand, the larger the channel pricing, inventory and supply chain profits, and the profit growth of dominant party is greater than that of followers.

Key words: stochastic market demand, dual-channel supply chain, game status, leader
