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 reveal the basic rules of endogenous spillover, a dynamic game model with two kinds of substitution rate parameters is established, and the product function positioning, pricing and innovation investment of level difference duopoly firms under endogenous spillover hypothesis are studied. Differences in product positioning under endogenous spillover typically show characteristics that vary between maximum and minimum differences as various parameters change, with the maximum and minimum differences being only special cases of the proposed model; between innovation input and innovation efficiency and absorptive capacity As well as the product positioning differences and the relationship between the parameters of several positive and negative correlation function, revealing the horizontal difference between the product endogenous spillover and low-cost innovation of some of the features.
