摘　　要：根据动态多维博弈理论,讨论了两个企业对具有一定替代性的两种产品的完全信息动态产量-价格二维博弈模型及其均衡,证明了两个企业关于无替代性的两种产品的产量-价格动态单独博弈模型是这种二维博弈模型的特例,并得到两个企业对每一种产品进行单独博弈的均衡策略劣于联合对两种产品进行二维博弈的均衡策略。结论表明,当两个企业对处于市场未饱和的一种产品产量策略和与其具有一定替代性的处于市场饱和的另一种产品价格策略同时进行二维博弈时,要充分考虑它们之间替代性,这样选择的产量和价格策略才是最优策略。According to the theory of dynamic multidimensional game, the paper discusses dynamic two-dimensional output-price game model with complete information for two kinds of products with certain substitution between two firms. It is proved that dynamic independent output-price game model for two kinds of products without certain substitution between two firms is a special case of this two-dimensional game model, and that equilibrium strategies in which two enterprises independently participate in game for every kind of product are inferior to equilibrium strategies in which each enterprise considers two kinds of product jointly to participate in the two-dimensional game. The results show that firms want to think over its substitution when two firms take two-dimensional game for a kind of product output strategies with unsat- urated market and another kind of product price strategies with saturated market, thus selected output and price strategies are optimal strategies.
