本文设置了一组可测量的变量和参数,建立低成本创新的产品价格决策及创新投入三阶段博弈模型,系统深入地研究了水平差异双寡头厂商的产品功能问题,获得了对低成本创新有重要意义的一系列新的结论。结果显示,内生溢出条件下厂商的均衡定位差异不同于线性成本模型和既往二次成本模型;本文得出了产品差异分布特点的更一般结论,显示出产品定位差异按照各种参数的变化呈现不同分布的现象,从而将原有特殊结论推广为一般结论;通过仿真模拟导出了创新投入、创新效率、吸收能力、产品定位差异的的一组函数关系。
Abstract
The hypothesis on endogenous spillover of innovation and R&D and a set of measurable variable and parameter are introduced; a three-stage model of product-pricing and innovation input of low-cost product is established and analyzed by using a three stage game model. A series of conclusion that are significant to low-cost innovation is found, that is, the equilibrium position of duopoly are neither minimum differentiation coming from linear cost model nor maximum one coming from quadratic cost model, the fact extends special cases into a general conclusion; a set of functional relationship between innovation input of firms and their innovation efficiency or absorption ability as well as between product position differentiation and varies parameters are found by analogue simulation.
