为了评价15类典型道路运输服务对社会公共影响的程度并比较定位,根据道路运输服务特征构建了判定道路运输服务社会公共影响程度的9个评价指标。结合专家调查法,采用主成分分析法获得了公益因子、环境因子、发展因子和安全因子共4个主成分,建立了判定道路运输服务社会公共影响程度的评价模型;根据计算结果,对15类道路运输服务按照社会公共影响程度大小进行了排序。研究结果表明:社会公共影响最大的前3类道路运输服务依次为危险品货物运输、城市公交和农村客运;15种典型运输服务社会公共影响程度排序对道路运输理论研究具有指导意义,可为政府针对各种服务制定有区别的发展政策提供参考,对运输企业实施不同服务的发展策略和经营管理也有很好的指导意义。
In order to evaluate the impact of 15 types of typical road transport services on the social public and compare them with each other, nine evaluation indexes are set up based on the characteristics of road transport services to determine the social public influence of road transport services. According to the expert investigation method, four principal components of public factor, environmental factor, development factor and safety factor were obtained by principal component analysis, and the evaluation model was established to determine the public influence degree of road transportation service. According to the calculation results, Road transport services are ranked according to the degree of social public influence. The results show that the first three types of road transportation services with the greatest social public impact are the transport of dangerous goods, urban public transport and rural passenger transport. The ranking of social public influence of 15 typical transport services is of guiding significance to the theoretical research of road transport and can be used by government It also provides reference for formulating differentiated development policies for various services and also has very good guiding significance for the development strategies and operation and management of transport enterprises in implementing different services.
