下游竞争者进入情形下投资供应商技术的排他性策略
Exclusivity Strategy in Supplier Technology Investment Under Downstream Rival Entry
摘要
Abstract
In the face of downstream rival entry and potential technology spillover,a buyer may adopt an exclusivity strategy when upgrading the supplier's production technology through investments.This paper explores how the exclusivity strategy affects downstream entry,and how the incumbent buyer develops such a strategy.First,it examines the impact of the exclusivity strategy on new rival entry and finds that the strategy can block the entry of an entrant buyer when both the investment cost and the penalty cost are low,provided that the supplier's production cost is high.Then,it analyzes the effect of the exclusivity strategy on technology spillover.The results show that the strategy can prevent technology spillover when both the investment cost and the production cost are low.In other cases,the strategy only prevents technology spillover if the cost is low;otherwise,the supplier will offer new technology to the entrant buyer.This paper further explores how the incumbent buyer designs an exclusivity strategy based on the firm entry.When the production cost is low,regardless of whether the investment cost is high or low,the incumbent buyer should set a high penalty.However,if the investment cost is very high,the penalty should not be excessively high.Then the production cost is medium or high,if the investment cost is low(or high),the incumbent buyer should set a low or high(high)penalty.If the investment cost is very high,the penalty should be set high but not excessively high.Finally,this paper investigates how the incumbent buyer shapes an exclusivity strategy based on technology spillover.If the production cost is low,the incumbent buyer should set a low penalty if the investment cost is low,and a low or high penalty if the investment cost is large.If the investment cost is very high,the penalty should not be set excessively high.For a high production cost,the incumbent buyer should set a low(low or medium)penalty,if the investment cost is low(or high).关键词
