以上海铁路、公路、水运、航空等各行业一些具有代表性的样本企业在一定时期内运行状况的实绩考评为背景 ,在建立了相应评价基准模型的基础上 ,根据样本企业各项实绩指标与基准指标值的正负偏离度导出综合偏差系数 ,并由综合偏差系数导出各行业的评价指数 ,从而起到衡量一个交通行业乃至整个交通运输系统运行状况的“晴雨表”作用
Based on the performance evaluation of some representative sample enterprises in Shanghai railway, highway, waterway and aviation industries over a certain period of time, based on the establishment of the corresponding evaluation benchmark model, according to the actual performance indicators of the sample enterprises The positive and negative deviation of the benchmark index value to derive the comprehensive deviation coefficient and the comprehensive deviation coefficient to derive the evaluation index of each industry so that it can serve as a “barometer” to measure the operation status of a transportation industry and even the entire transportation system
