Abstract: As the price gap between diesel and natural gas widens and the advancement and implementation of dual carbon goals proceed, gas power takes up over 70% of the heavy-duty commercial vehicle segment for long-distance rated-load logistics. Serving as the core powertrain, gas engines confront mounting market competition, which brings fresh challenges to automakers in power selection and pricing amid fierce industrial competition. This paper selects the typical segmented market of long-distance rated-load logistics as the research scope and sets gas engines as research subjects. It constructs an analytic hierarchy model for gas engine premiums with five primary indicators including brand, market share, performance, quality and after-sales service as well as nineteen secondary indicators. The analytic hierarchy process-criteria importance through intercriteria correlation (AHP-CRITIC) hybrid method calculates weights at all hierarchical levels of the model from field operation and experimental data of sample A, sample B and sample C. The barrel effect is incorporated into the analysis to complete quantitative measurement of premium capacity for gas engines of diverse brands and models. Findings prove that the proposed model delivers scientific assessment of premium performance of gas power, and lays theoretical foundations for gas engine selection, precise market pricing and subsequent product iteration.

摘要： 随着柴油与天然气价格差拉大和“双碳”目标推进落地，燃气动力在重型商用车长途 标载物流市场的占比已超 70%，燃气发动机作为核心动力总成，市场竞争日趋激烈，在行业 内卷背景下整车动力选型、定价方面也面临新挑战。文章聚焦长途标载物流这一典型细分市 场，以燃气发动机为研究对象，构建了包含品牌、市场占有率、性能、质量、售后服务 5 个 一级指标及 19 个二级指标的燃气发动机溢价层次分析模型，采用层次分析-客观赋权 （AHP-CRITIC）混合法，基于样本 A、样本 B、样本 C 机型的实际运营数据和试验数据计算 出了模型中各个层级之间的权重，同时考虑木桶效应，最终量化了不同品牌型号燃气发动机的 溢价能力。研究表明，该模型能够科学地评估燃气动力溢价能力，为燃气发动机选型、产品 市场精准定价与产品迭代提供理论依据。
