【摘要】 在AJ模型的基础上,引入R＆D竞争均衡的稳定性分析,通过比较R＆D竞争与联合实验室的均衡策略发现:当竞争均衡对称且稳定时,联合实验室中的企业利润和社会福利水平都较高;而在非对称竞争均衡情况中,评价联合实验室与R＆D竞争的优劣需要更为严格的市场参数条件.更多还原

【Abstract】 Equilibrium stability analysis in R&D competition was introduced into AJ model.Equilibrium comparison between R&D competition and joint laboratory was carried out. as stable and symmetric competition equilibrium exists, the profit and welfare of joint lab are higher. as stable and asymmetric competition equilibrium exit, however, the estimation on joint laboratory R&D competition needs stricter market parameters.更多还原
