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)。
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.
