本文构建三阶段动态博弈模型,从纵向市场势力的角度考察了影响本土小型零售商自主创新的因素。研究结论表明：买方抗衡势力差异是造成本土小型零售商自主创新能力较弱的重要原因,之所以出现这一结论是因为买方抗衡势力对不同类型零售商创新的影响不同。买方抗衡势力对大型零售商创新的影响与零售商竞争程度有关,当零售商竞争程度较弱时,大型零售商的创新水平随买方抗衡势力增强而增加;当零售商竞争程度较强时,大型零售商的创新水平随买方抗衡势力增强先增加后减小。买方抗衡势力对小型零售商创新的影响与竞争程度无关,随着买方抗衡势力增强,小型零售商的创新水平先减小后增加。在此结论基础之上,论文提出了促进本土小型零售商创新的建议。

英文摘要：

This paper studies the factors that lead to weak innovation ability of small retailers from the perspective of vertical market power by constructing a three stage dynamic game model.The study shows that the difference of countervailing power between retailers is an important reason for the weak innovation ability of small retailers.This conclusion results from the different impacts of countervailing power on retailers.The impact of countervailing power on big retailer＇s process innovation is related to the degree of competition between small retailer and big retailer.When the degree of competition is low,the process innovation level of big retailer increases with countervailing power.When the degree of competition is high,the process innovation level of big retailer firstly increases and then decreases with the countervailing power.However,the process innovation level of small retailers always decreases firstly and then increases with the countervailing power.Based on the conclusions of the paper,we put forward some suggestion of promoting the innovation of small retailers.
