我们分析了寡头垄断企业在研发溢出情况下的研发和产出行为，前提是这些企业在研发方面存在推测性差异。通过使用猜想变异方法，先前的研发研究扩展到更一般的分析，并且更加阐明了许多行业中实际企业的行为。本文表明，企业在研发决策中采取积极行动还是消极行动，对研发和产出行为的影响完全相反。事实证明，常规结果在一系列竞争或共谋下也成立。研发中的简历在决定技术改进水平方面发挥着至关重要的作用。
We analyze R&D and output behavior of oligopolistic firms under R&D spillover when they possess conjectural variations in R&D. By use of the conjectural variations approach, the preceding researches on R&D are extended to more general analysis and the behavior of actual firms in a lot of industries are more elucidated. This paper shows that the results on the R&D and output behavior are totally reversed by whether firms act in an aggressive or a passive way in the R&D decision. It is demonstrated that the conventional results hold under a range of competition or collusion as well. CVs in R&D play a crucial role in determining the level of technological improvement.
