To promote the green transformation of the shipping industry and improve environmental responsibility awareness among shipping enterprises, this paper presents a game model with two enterprises that differ in their awareness of environmental responsibility. The model uses non-cooperative game theory to study how environmental responsibility awareness affects investment in green shipping and the economic utility of enterprises during market competition. The results of the study show that the optimal level of investment in green shipping is determined solely by the cost-benefit analysis of the investment itself, rather than by the investment levels of other companies or the market environment. When there is a large gap in environmental responsibility awareness among shipping companies or when indirect cargo profit and loss is too low, enterprises' willingness to transform to green shipping will weaken during competition, as enterprises that take the initiative to transform to green shipping will lose their competitive advantage due to excessive encroachment on productive resources and reduced economic efficiency. Furthermore, to ensure that the overall utility of the shipping market improves with the depth of green transformation, it is necessary to control the cost of green investment, improve the return on investment of green shipping and reduce the pressure on enterprises to transform to green shipping. Based on the analysis results, it is recommended that the government promulgates policies and regulations to unify green shipping standards, encourage technological innovation in shipping and promote industry synergy and technology sharing, in order to achieve continuous green transformation.

为科学推动航运业绿色转型、提高航运企业环境责任意识，文章建立了一个由两家环境责任意识水平不同的航运企业组成的产量博弈模型，深入研究市场竞争过程中环境责任意识对企业绿色航运投资水平和经济效用的影响。研究结果表明，企业的最优绿色航运投资水平只受到投资本身的成本和收益影响，而与其他公司的投资水平和市场环境无关。当航运公司间环境责任意识差距过大或间接货运损益过低时，在企业竞争过程中，主动进行绿色航运转型的企业出于环境保护要求会出现生产性资源被过度侵占、经济效益降低从而失去竞争优势的情况，此时绿色航运转型意愿会被削弱。另外，为保证航运市场的总体效用随着绿色转型的深入而提高，需要控制绿色投资成本、提高绿色航运的投资回报率，减小企业绿色转型压力。最后，基于分析结果，建议政府颁布政策法规统一绿色航运标准、鼓励航运技术创新、推动行业协同与技术共享等以实现绿色转型持续推进。
