【摘要】 本文研究不对称性(初始成本、创新率、溢出水平)对半合作创新模式下的企业间的研发投入、产量、利润对比以及社会福利水平造成的影响.我们建立了该创新模式下的不对称双寡头博弈模型,运用数值模拟对模型的均衡解进行比较分析后发现:具有初始成本优势的企业研发投入、产量、利润较高;具有创新率优势的企业研发投入、产量较高,但利润的相对大小与溢出水平有关;溢出不对称情况下,溢出小的企业研发投入较低,产量、利润较高;当初始成本差距越小、创新率差距越小、企业溢出都非常低或非常高时,社会福利较高.更多还原

【Abstract】 This paper aims at analyzing the effect of asymmetry on R&D expenditures,output, profit and welfare for two agents of different initial cost,innovation rate and spillover with semi-col- lusion.Asymmetric duopolistic is proposed.Simulations show that the agent with lower initial cost has higer R&D expenditures,output and profit;the agent with higher innovation rate also has higer R&D expenditure and output.Whether its profit is higer depends on the two agents’s spillover.The agent with lower spillover always has lower R&D expenditure,but higer output and profit.The lower the difference of the two agnts’ initial cost is,the lower that of innovation rate is,and the nearer to 0 or 1 the two agents’ spillover is,the higher welfare is.更多还原
