摘要
当企业进行产品创新时,升级后的产品面临重新定价并带来市场竞争格局的改变.针对这一问题,将双寡头企业非对称R&D行为引入Hotelling模型,同时将传统Hotelling模型中外生的定价策略作为内生变量,研究技术溢出条件下的两阶段R&D/产品问题.研究发现,产品创新是提升企业竞争力的有效途径,歧视定价是企业获得超额利润的占优策略.在均衡定价策略下,创新企业表现出明显的研发"惰性,"R&D投入与技术溢出水平负相关.当政府对企业产品创新实施补贴时,创新企业则表现出研发过度的行为特征,R&D投入与技术溢出水平正相关,在均衡定价策略下,企业过度研发行为受到抑制,社会福利水平最高.
When a firm conducts product innovation, the upgraded product will be re-priced, and market competitive manner will be changed. As for that, introducing the asymmetric R＆D behavior of duopoly into Hotelling model, and taking the product pricing strategy in traditional Hotelling model as an endogenous variable, it studies the two-stage R＆D/product model under the condition of technological spillovers. It concludes that product innovation is an effective way to enhance firm＇s competitiveness, and discriminatory pricing is the dominant strategy for each firm. Under the equilibrium pricing strategy, the innovative firm shows the feature of ＂R＆D inertia＂, and there is a negative relation between R＆D input and technological spillovers. When the government provides R＆D subsidies, the innovative firm shows the feature of ＂R＆D excess＂, and a positive relation exists between firm＇s R＆D input and technological spillovers. Under equilibrium pricing strategy, the finn＇s excessive R＆D behavior is restrained and the social welfare reaches the highest level.
