基于结构方程模型的绿色铁路建造能力形成机理研究

Mechanism of green railway construction capacity formation based on structural equation modeling

在“碳达峰碳中和”双碳目标驱动下,铁路的绿色转型势在必行,然而目前铁路工程企业绿色铁路建造能力尚显不足,究其原因是由于绿色铁路建造能力建设目标不明确、依据不充分。首先,通过文献分析归纳出绿色铁路建造能力的4个构成维度,筛选识别出5类影响因素和23个影响因素指标。其次,根据绿色铁路建造领域相关研究成果提出影响因素作用的研究假设,建立结构方程概念模型。最后,通过调查问卷进行数据收集,进行理论模型的拟合和检验,再基于拟合结果分析揭示各影响因素对企业绿色铁路建造能力的作用效应。研究结果表明:企业技术发展及人才建设水平、行业发展水平、企业内部绿色发展水平、企业综合管理水平和政府推力对绿色铁路建造能力均有显著正向影响,且影响效应依次递减;政府推力和行业发展水平仅对绿色铁路建造能力产生间接影响,企业内部绿色发展水平、企业综合管理水平和企业技术发展及人才建设水平仅起直接作用。研究揭示了绿色铁路建造能力的形成机理,为提高企业绿色铁路建造能力提供理论依据,有助于提高铁路工程企业对绿色铁路建造能力的认知水平,帮助其快速实现绿色转型。

Driven by the 30-60 double carbon target,the green transformation of railway is inevitable.However,the current green railway construction capacity of railway engineering enterprises is still insufficient,and the reason is due to the unclear goal and insufficient basis for green railway construction capacity building.Firstly,this paper summarized four constitutive dimensions of green railway construction capacity through literature analysis,screen and identify five types of influencing factors and 23 influencing factor indicators.Secondly,the research hypothesis of the role of influencing factors was proposed,and the conceptual model of structural equation was established according to the relevant research results in the field of green railway construction.Finally,the data were collected through questionnaires,the theoretical model was fitted and tested,and then the effect of each influencing factor on the green railway construction capacity of enterprises was analyzed based on the fitting results.The research results are shown as follows.Enterprise technology development and talent building level,industry development level,enterprise internal green development level,enterprise comprehensive management level and government thrust have significant positive effects on green railway construction capacity.The effects are decreasing in order.Government thrust and industry development level only have indirect effects on green railroad construction ability,and enterprise internal green development level,enterprise comprehensive management level and enterprise technology development and talent building level only play a direct role.The results can reveal the formation mechanism of green railway construction capacity,provide theoretical basis for improving the green railway construction capacity of enterprises,help to improve the cognitive level of railway engineering enterprises on green railway construction capacity,and help them to realize green transformation rapidly.
