琦文分享（一）考虑双均衡的港航供应链可持续投资研究

　　原文摘要：
　　针对港航联合碳减排问题，构建了静态 Stackelberg 均衡与动态演化博弈双均衡联动模型，在政府碳排放规制和碳交易市场双重因素下，研究考虑可持续发展的港航供应链低碳技术投资策略。研究表明：随着投资成本分担比例的增大，在静态 Stackelberg 均衡下，航运公司投资意愿逐渐降低，而港口却始终偏好自身投资，此时系统均衡策略由航运企业投资的囚徒困境转变为港口投资的帕累托最优；在动态演化博弈下，稳定结果是航运企业投资转变为港口投资。并从政府-市场-企业三方视角发现：（ 1）企业长期低碳投资策略与政府碳排放限额无关；（ 2）企业需要关注低碳市场价格、托运人对可持续水平敏感度以及分担比例，这些参数值增高会降低碳排放量；（ 3）随着价格敏感度的增大，碳排放量呈现先上升后下降的趋势。最后结合静态与动态投资策略，为政府、港口和航运企业可持续投资提供建议。
　　赏析：该摘要也是资料型的摘要写法，通过摘要，我们可以清晰地看到整篇论文的工作大纲，分析如下：
　　＂目的＂--我为什么研究这篇论文：在政府碳排放规制和碳交易市场双重因素下，研究考虑可持续发展的港航供应链低碳技术投资策略
　　＂方法＂：构建了静态 Stackelberg 均衡与动态演化博弈双均衡联动模型
　　＂结果＂：研究表明：随着投资成本分担比例的增大，在静态 Stackelberg 均衡下，航运公司投资意愿逐渐降低，而港口却始终偏好自身投资，此时系统均衡策略由航运企业投资的囚徒困境转变为港口投资的帕累托最优；在动态演化博弈下，稳定结果是航运企业投资转变为港口投资。
　　＂结论＂：（ 1）企业长期低碳投资策略与政府碳排放限额无关；（ 2）企业需要关注低碳市场价格、托运人对可持续水平敏感度以及分担比例，这些参数值增高会降低碳排放量；（ 3）随着价格敏感度的增大，碳排放量呈现先上升后下降的趋势。最后结合静态与动态投资策略，为政府、港口和航运企业可持续投资提供建议。
　　本文的摘要非常简洁，没有一句话是多余的，包含了文章的所有信息。
　　Appreciation: The abstract is also a data-based abstract. Through the abstract, we can clearly see the work outline of the entire paper. The analysis is as follows:
　　＂Purpose＂-Why did I study this paper: Under the dual factors of government carbon emission regulations and carbon trading market, to study the sustainable development of low-carbon technology investment strategies in the port and shipping supply chain
　　＂Method＂: Constructed a dual equilibrium linkage model of static Stackelberg equilibrium and dynamic evolutionary game
　　＂Result＂: The research shows that with the increase of the investment cost sharing ratio, under the static Stackelberg equilibrium, the shipping company＂s investment willingness gradually decreases, but the port always prefers its own investment. At this time, the system equilibrium strategy is the prisoner＂s dilemma of the shipping company＂s investment. The Pareto Optimal Transformation into Port Investment; Under the dynamic evolutionary game, the stable result is that the investment of shipping companies transforms into Port investment.
　　＂Conclusion＂: (1) The long-term low-carbon investment strategy of the company has nothing to do with the government＂s carbon emission limit; (2) The company needs to pay attention to the low-carbon market price, the shipper’s sensitivity to sustainable levels, and the share ratio. Increased values of these parameters will reduce carbon. Emissions; (3) As the price sensitivity increases, carbon emissions show a trend of rising first and then falling. Finally, it combines static and dynamic investment strategies to provide suggestions for sustainable investment by the government, ports and shipping companies.
　　The summary of this article is very concise, no sentence is superfluous, and it contains all the information of the article.

　　表示论文研究结果、结论的关键词。本文最终的研究目的是为政府、港口和航运企业的可持续投资提供建议，所以选择可持续投资作为关键词。
　　Appreciation: We pide keywords into three categories
　　1. Thematic keywords: port and shipping supply chain
　　Indicates the research topic of this article.
　　2. Process keywords: Stackelberg model; evolutionary game
　　Indicates the theories, methods, models, etc. used in the research process.
　　3. Resulting keywords: sustainable investment
　　Key words that indicate the research results and conclusions of the thesis. The final research purpose of this article is to provide suggestions for sustainable investment of governments, ports and shipping companies, so sustainable investment is chosen as the key word.
　　引言赏析
　　我们将引言也分为三个部分赏析。
　　第一部分：首先告诉读者，我为什么做这个研究，这个研究的重要性在哪里？
　　We will also pide the introduction into three parts for appreciation.
　　Part 1: First tell the reader why I did this research, and what is the importance of this research?
　　随后，作者为体现该研究可持续发展和低碳投资的重要性，分别对＂国籍航运碳排放的发展＂、＂政府努力推进港口可持续运营＂、＂客户的低碳意识对港航供应链的促进＂方面进行了文献综述。
　　Subsequently, in order to reflect the importance of sustainable development and low-carbon investment in this research, the author separately discussed the ＂development of national shipping carbon emissions＂, ＂government efforts to promote sustainable port operations＂, and ＂customers＂ low-carbon awareness on the port and shipping supply chain. A literature review was conducted on the ＂promotion of＂.
　　引言赏析
　　第二部分：指出现有研究和本文研究的gap。
　　The second part: Point out the existing research and the gaps studied in this article.
　　引言赏析
　　第三部分：指出本文要去解决的研究问题
　　Part Three: Point out the research problem to be solved in this article
　　模型赏析
　　本文的特点在于结合了动态演化模型与静态Stackelberg模型分析短期和长期的港航供应链低碳技术投资决策。单独的模型使用十分常见了，小编认为这段双联动分析还是颇有新意的。
　　The feature of this paper is that it combines the dynamic evolution model and the static Stackelberg model to analyze the short-term and long-term low-carbon technology investment decisions of the port and shipping supply chain. The use of separate models is very common, and I think this double linkage analysis is quite innovative.
