供应链中企业交叉持股的定价和绩效的变化影响供应链上企业的合作关系乃至供应链竞争力的发挥。文章首先借助Stackelberg博弈模型讨论供应链中交叉持股对企业的影响,定量地推演无交叉持股前、交叉持股时和纵向一体化情况下定价和收益的差异;然后通过对推演结果的分析得出结论:交叉持股可以使市场价格下降的同时使供应链中企业的总收益增加;最后通过比较交叉持股与纵向一体化的外部效应,提出支持交叉持股、限制过度纵向一体化的企业战略建议。
Changes in the pricing and performance of cross-shareholdings in the supply chain affect the cooperation between enterprises in the supply chain and the competitiveness of the supply chain. Firstly, this paper discusses the impact of cross-shareholding in the supply chain on the firm with the help of Stackelberg game model, and quantitatively deduces the difference between pricing and return without cross-holding, cross-shareholding and vertical integration. Then through the analysis of the result of the deduction It concludes that the cross-shareholding can make the market price drop at the same time increase the total return of the enterprises in the supply chain. Finally, by comparing the external effects of cross-shareholding and vertical integration, we propose to support cross-shareholding and limit excessive vertical integration Business strategy advice.
