供应链转型升级视角下的供应商研发决策研究

Research on Supplier R&D Decision from the Perspective of Supply Chain Transformation and Upgrading

当现有产品处于不同的产品生命周期阶段时,面对下游制造商向市场导入新产品的情况,上游供应商独立开展的新产品零部件的研发决策会有所不同。考虑到在新产品导入初期,新产品和现有产品在市场上并存的情况,论文在Bass扩散模型的基础上,研究现有产品和新产品在产品生命周期中逐渐渗透到潜在市场的扩散路径,计算并比较整个生命周期内供应商在不同研发决策下的利润,从而确定供应商关于新产品零部件的研发决策选择。研究发现当新产品与现有产品差异较小时,新产品导入的时间越靠近现有产品生命周期的前端(即成长期),供应商更愿意选择研发新产品的配套零部件;当新产品与现有产品差异较大时,新产品导入的时间越靠近现有产品生命周期的后端(即衰退期),供应商越愿意选择研发新产品的配套零部件。

When the original product is in different stages of product life cycle,facing the situation that a downstream manufacturer introduces an innovative product to the market,the R D decision of innovative product parts independently carried out by the upstream supplier will be different.Considering that an innovative product and an original product coexist in the market in the introduction stage of the new product,we study the diffusion path of an existing product and an new product in the product life cycle,then calculate and compare the supplier'profits under different RD decisions,so as to determine the supplier'RD decisions on new product components.The results show that when the innovation degree of the innovative product is small,the more the original product is in the front of the product life cycle(i.e.the growth period),the more willing the supplier is to invest in the supporting parts of the innovative product.When the innovation degree is large,the later the existing product is in the product life cycle(i.e.recession period),the more willing the supplier is to invest in R D.
