当企业R&D资源存在互补性时,分析了企业先进行减少成本的R&D投资再在产品市场上进行Bertrand竞争的一类两阶段模型.比较了当R&D分别采取完全竞争和非合作的合资形式时企业相对技术改进量的大小.表明当企业R&D投入的互补性较强时合资R&D所带来的技术改进量较大,而当R&D投入的互补性较弱时则相反.
When enterprises’ R & D resources are complementary, a two-stage two-stage model of the competition between Bertrand and the R & D investment in cost reduction is analyzed.Compared with the case of R & D when the two companies take the completely competitive and non-cooperative joint venture The relative amount of technical improvement shows that the joint venture R & D brings about a large amount of technical improvement when the R & D investment is highly complementary and the opposite is true when the R & D investment is weakly complementary.
