摘要
随着我国“碳达峰”“碳中和”目标的提出,铁路行业的绿色化发展势在必行。铁路工程企业作为行业发展中的重要参与者,亟需深化对绿色铁路的认识和实践,加强自身绿色铁路建造能力建设。为此,基于文献研究,从企业绿色铁路建造能力的特点出发,识别企业绿色铁路建造能力的影响因素,运用系统动力学方法构建企业绿色铁路建造能力仿真模型,对模型的关键变量进行敏感性测试,揭示影响因素对企业绿色铁路建造能力的作用规律。模型仿真结果与2015~2020年国家铁路单位综合能源消耗实际情况基本吻合,验证了本研究所构建仿真模型的有效性。在模型仿真结果的指导下,针对性地提出企业绿色铁路建造能力提升的对策建议。研究结果表明:节能环保技术创新、政策支持力度和人才培养水平是企业绿色铁路建造能力的关键影响因素,且从技术、制度、资源和文化4个方面对企业绿色铁路建造能力均产生较大的正向影响。研究结果可帮助企业加强对绿色铁路建造能力的科学认识,为企业绿色铁路建造能力提升及方案制定提供理论依据与参考指导。
With the proposal of “carbon peak” and “carbon neutral” in China,the green development of railway industry is imperative.As an important participant in the development of the industry,railway engineering enterprises should strengthen the understanding and practice of green railway,and strengthen the green railway construction capacity.Therefore,from the characteristics of green railway construction capacity of enterprises based on literature research,the influencing factors of green railway construction capacity of enterprises were identified.Based on this,the system dynamics method was used to build a simulation model of the green railway construction capacity of enterprises.The sensitivity test of the key variables of the model was carried out to reveal the law of influence factors on the green railway construction capacity of enterprises.The simulation result basically matches with the actual situation of 2015~2020 national railway unit comprehensive energy consumption,verifying the effectiveness of the simulation method.Under the guidance of the model simulation results,effective suggestions for improving the green railway construction capacity of enterprises are put forward.The results show that the energy conservation and environmental protection technology innovation,policy support and personnel training level are three key factors of the green railway construction capacity of enterprises.Those have great positive effects on the construction ability of green railway enterprises from four aspects of technology,system,resource,and culture.Therefore,the research results can help enterprises strengthen their scientific understanding of green railway construction capacity,provide theoretical basis and reference for enterprises to improve their capacity of green railway construction and make corresponding plans.
