We show that whether a technology leader invests more in R&D compared to a technology follower may depend on the R&D process and whether the follower is in the market. Considering Cournot competition, we show that if the firms are in the market, the technology leader (follower) invests more in R&D under a step-by-step R&D process (when the firms target similar technologies). However, if the technology follower can enter the market only if it is successful in R&D, the technology follower may invest more (invests more) in R&D under the step-by-step R&D process (when the firms target similar technologies). We also show the implications of Bertrand competition.

研发竞争与技术领先的持久性

我们表明，与技术追随者相比，技术领先者是否在研发上投入更多可能取决于研发过程以及追随者是否在市场上。考虑到古诺竞争，我们表明，如果公司在市场上，技术领先者（追随者）在逐步研发过程中（当公司瞄准类似技术时）在研发上投入更多。但是，如果技术追随者只有在研发成功后才能进入市场，那么技术追随者可能会在逐步研发过程中（当公司瞄准类似技术时）在研发上投入更多（投入更多）。我们还展示了 Bertrand 竞争的影响。
