不同竞争模式下制造商创新投入决策影响研究

基于不同市场结构下的博弈模型，探讨了横向与纵向维度下的不同竞争模式对上游制造商创新投入决策的影响.研究表明，横向市场竞争强度对上游制造商的创新投资意愿具有负面抑制作用，而纵向市场势力对上游制造商的创新投资愿意具有正面促进作用，但与无竞争压力的基准情形相比，无论是横向竞争还是纵向竞争，均会降低制造商进行创新研发投资的动机性，且来自于横、纵维度的双重竞争压力会加剧这种抑制作用.最后通过数值分析，验证了所得结果的正确性.

Research on Impacts of Manufacturers ' Innovation Investment Decision-Making Under Different Competition Modes

Based on the game models under different market structures， the impacts of different competition modes on upstream manufacturers’ innovation investment decision-making in horizontal and vertical dimensions were discussed. The results showed that the horizontal market competition intensity has a negative effect on upstream manufacturers’ innovation investment willingness， while the vertical market power has a positive effect on upstream manufacturers’ innovation investment willingness. However， compared with the benchmark situation without competition pressure， both horizontal and vertical competition will reduce manufacturers’ motivation to invest in research and development innovation， and the double competition pressure from the horizontal and vertical dimensions will aggravate this inhibition. Finally， through numerical analysis， the correctness of the obtained results is verified.
