基于服务竞争的航运供应链的纵向整合决策

在港口服务竞争下构建两条平行竞争的港口—承运商—货代三级航运供应链,研究承运商的纵向整合决策,并结合货主效益识别不同整合策略的可行条件及其均衡特征。研究发现,对手链的整合策略仅影响自身链是否选择纵向整合。当承运商选择整合策略时,前向整合策略的选择取决于港口服务竞争程度,而后向整合策略的选择则与港口服务投入系数有关。在对手链不同的整合策略下,都存在一个最优条件,此时承运商选择后向整合能够同时最大化自身利润和满足货主期望。

Vertical Integration of Shipping Supply Chain Under Service Competition

Under port service competition, two parallel three-tier shipping supply chains, each of which is composed of a port, a carrier and a freight forwarder, are constructed to study the carrier's vertical integration decision and identify the feasible conditions and equilibrium characteristics of different integration strategies combining with the shipper's benefit. We find that the rival chain's integration strategy only has an impact on whether the carrier adopt integration or not, but makes no difference on its specific integration selection. Carrier's forward integration depends on the degree of port service competition , while the forward backward integration depends on the port service cost coefficient. Under the different integration strategies of the rival chain, there exists an optimal condition where carrier choosing backward integration can maximize its profit meanwhile achieve the shipper's benefit expectations.
