摘要
在由一个上游和一个下游企业组成的体系中 ,每个企业通过 R&D可降低产品成本 .研究了企业 R&D投资和下游产品产量随纵向一体化的变动情况 ,结果表明 ,纵向一体化之后 ,每个企业的 R&D投资和下游产品产量、行业利润、消费者剩余和社会总福利均增加 .在纵向一体化之前 ,R&D投资和下游产品产量较少的原因是每个企业作出决策时没有考虑另一个企业的利润 .
Each firm can reduce its product's cost through R&D in a system composed of an upstream and a downstream firm. This paper studied how the R&D investments and the downstream output vary with vertical integration. It is shown that, after the vertical integration, each firm's R&D investment, the downstream output, the industry profit, the consumer surplus and the social welfare are all increased. Before the vertical integration, the lack of the R&D investments and downstream output is due to the fact that each firm's decision does not consider its counterpart's profit. A special example was given to further demonstrate the results of this paper.
