存在研发投资溢出时的企业市场绩效分析

An Analysis on the Firm Market Performance under R&D Investment Spillover

在古诺竞争市场结构下,建立了具有R&D过程的双寡头博弈模型,从促进技术进步、产品的价格、企业的生产规模、企业的利润以及总福利的角度出发,分析了存在研发投资溢出时,在不同的R&D策略下企业的市场绩效。研究表明,企业的市场绩效不仅与研发投资溢出率以及产品的差异度大小有关,而且与R&D效率的高低有关。

This paper constitutes a model of the duopoly with R&D process under the market structure of Cournot competition.It analyzes the market performance of firm under the different strategic R&D with output spillover through the perspectives of technology progress,the price of product,the output and profit of the firms and the total welfare.Thus a key finding of the paper is that the market performance of the firms is not only relevant to R&D output spillover coefficient and differential degree of product but also R&D efficiency.
