摘要
为揭示内生溢出的基本规律,建立了含有两种替代率参数的动态博弈模型,研究了在内生溢出假设下水平差异双寡头厂商的产品功能定位—–定价和创新投入问题.研究发现,内生溢出条件下产品定位差异一般显示出按各种参数的变化在最大与最小差异之间分布的特点,最大和最小差异仅仅是所提出模型的特例;创新投入与创新效率和吸收能力之间以及产品定位差异与各参数之间存在几种正相关与负相关函数关系,揭示了水平差异产品内生溢出和低成本创新的一些特点.
To demonstrate basic laws of endogenous spillover of innovation,a kind of three-stage dynamic game theory modle with two substitution rates is introduced to probing positioning-pricing innovation input and analyzed by using a game model.It is found that the equilibrium position of duopoly distributes between minimum and maximum differentiation which are merely special cases in new model.Some types of increasing or decreasing functions exist between innovation input of firms and their innovation efficiency or absorption ability as well as between position differentiation and parameters,which shows the characteristic of endogenous spillover and low cost innovation of equilibrium differentiation.
