题目港口应对气候变化灾害的投资决策:码头运营商的市场结构以及港口间和港口内的竞争合作

Title: Seaport Adaptation to Climate Change-related Disasters: Terminal operator market structure and inter- and intra-port coopetition

摘要Abstract

随着跨国码头经营公司(GTO)在港口运营中的兴起,码头运营商(TOC)的市场结构在决定港口内和港口间竞争与合作(即竞合)方面变得越来越重要。港口对气候变化相关灾难的预防性投资也可能受到这种TOC港口内和港口间竞合的影响。本文利用经济学模型,理论地研究了TOC市场结构如何影响港口的灾害预防投资。更具体地说,我们考虑一个区域内两个相互竞争的港口。这两个港口面临不确定的灾难威胁,并且TOC数量不对称。我们的模型分析和数值结果表明,本港或竞争港口TOC竞争强度对港口的灾害预防投资产生了相反的影响。跨港口TOC合资(JV)将减少两个港口的灾害预防投资。此外,我们发现TOC市场结构可以改变港口对于灾难不确定性的态度。也就是说,TOC港口内和港口间的竞合可以增强或减弱港口对灾难发生不确定性的敏感性。最后,我们还发现区域社会福利随着两个港口的总的灾害预防投资单调增加。所以建议监管机构鼓励新的TOC进入,同时限制跨港口TOC合资。

With the prevalence of global terminal operators (GTOs) in port operation, the market structure of terminal operator companies (TOCs) becomes more important in shaping intra- and inter-port competition and cooperation (i.e., coopetition). The port adaptation investment to climate change-related disaster might also be affected by such TOC intra- and inter-port coopetition. This paper examines analytically how the TOC market structure could affect ports’ adaptation investment. More specifically, we consider two landlord-type ports within a region that compete with each other. The two ports are subject to uncertain disaster threats and have an asymmetric number of TOCs. Our analytical and numerical results suggest that more TOCs at own port and the competing port have opposite impacts on the port’s adaptation investment. Inter-port TOC joint venture (JV) would decrease adaptation at both ports. Moreover, TOC market structure is found to moderate the effect of disaster uncertainty on port adaptation. That is, TOC intra- and inter-port coopetition can strengthen or weaken ports’ sensitivity to disaster occurrence uncertainty. Finally, the regional welfare is found to monotonely increase with two ports’ total adaptation. The regulators are suggested to encourage new TOC entries while restricting inter-port TOC JVs. The cases with heterogeneous disaster uncertainties at two ports are also examined.
