摘要我们考察了企业成本不对称对R&D投资的影响。我们得到了五个新的结果。首先，非合作R&D投资与合作R&D投资的社会偏好与企业成本不对称程度无关。第二，低成本企业的R&D投资大于高成本企业的研发投入。第三，对于较小的溢出效应，非合作R&D投资与市场竞争程度呈U型曲线关系。第四，随着市场竞争的加剧，低成本(高成本)企业可能会减少(增加)其非合作研发投资。第五，随着市场竞争的加剧，低成本企业与高成本企业的利润差距增大。
ABSTRACT We examine the effects of firms' cost asymmetry on R&D investments. We obtain five novel results. First, the social preference between noncooperative and cooperative R&D investments is independent of the degree of firms' cost asymmetry. Second, R&D investments of low-cost firms are larger than those of high-cost firms. Third, for a small spillover, noncooperative R&D investments have a U-shaped curve with the degree of market competition. Fourth, as market competition intensifies, a low-cost (high-cost) firm may decrease (increase) its noncooperative R&D investment. Fifth, the difference in profit between low-cost and high-cost firms increases with the degree of market competition.
