邮轮旅游供应链研发投入研究——基于演化博弈模型

Research on R&D Investment in Cruise Tourism Supply Chain—Based on Evolutionary Game Model

向绿色低碳转型是我国船舶工业当今的发力点,今年年初起,针对现有船只的碳强度指数及排放指数正式生效,航运业的低碳转型之路开始加速。造船厂和邮轮公司对减排技术和广告宣传的合理投入,对提升邮轮的品牌形象以及供应链的整体收益有重要意义。本文建立了造船厂和邮轮公司之间的博弈模型,比较研究了两个主体合作与否以及邮轮公司是否分担造船厂对减排技术投入成本对邮轮旅游供应链整体收益的影响。研究发现,两个主体合作时的供应链整体收益以及对减排技术和广告宣传的研发投入水平均高于不合作时;两个主体不合作时的两种情形下,其供应链整体收益以及对减排技术和广告宣传的研发投入水平的高低取决于旅游社出售价格和邮轮公司价格之间的大小关系。

The transformation to green and low-carbon is the driving force of China’s shipbuilding industry today. Starting from the beginning of this year, the carbon intensity index and emission index for existing ships have officially come into effect, and the low-carbon transformation of the shipping industry has begun to accelerate. The reasonable investment of shipyards and cruise companies in emission reduction technology and advertising is of great significance to enhance the brand image of cruise ships and the overall revenue of the supply chain. This paper establishes a game model between shipyards and cruise lines, and compares the impact of whether the two entities cooperate and whether cruise companies share the input cost of shipyards on the emission reduction technology input costs on the overall revenue of cruise tourism supply chain. The study found that the overall revenue of the supply chain when the two entities cooperated, as well as the average level of R&D investment in emission reduction technology and advertising, was higher than that of non-cooperation;in both cases when the two entities do not cooperate, the overall revenue of the supply chain and the level of investment in R&D and investment in emis-sion reduction technology and advertising depend on the size of the relationship between the selling price of the tour agency and the price of the cruise company.
