| 摘 要： | 本文通过将研发投资和产品生产视作相互独立的变量、引入虚拟局中人以揭示合作动机,同时去除企业的事前对称性假设,得出与传统的研发合作策略研究不同的结论。本文发现具有下列特征之一的企业更倾向于合作研发:较高的市场份额,较高的边际成本节约、较大的风险规避度、较强的吸收能力,较高的边际吸收能力、未来市场的领导者;或者企业面临下列市场处境之一时,也具有更大的合作可能性:较高的技术共享水平,较弱的未来市场竞争。总之,合作企业的研发投资变化方向取决于假定投资增加后自身β-定产边际成本节约的变化(合资中)或总体的β-定产边际成本节约的变化(技术共享联盟中)。

| Abstract: | This paper presents different conclusions with that in the literature,using three approaches: treating R&D investment and post-innovation output independently,introducing a virtual player to reveal cooperative incentives and eliminating the symmetry of members.The authors find that firms with one of the following characteristics are prone to cooperate: large output in the future,high marginal cost reduction,large degree of risk-averse,strong absorptive capacity,leaders;or that firms facing the following circumstances are likely to cooperate: high spillovers,unserousness in the future competition.All in all,the move of firm's R&D investment must consistent with the direction of its(the alliance's) marginal aggregate cost reduction with spillovers for fixed prospective outputs. |
