摘要
本文讨论了铁路通信信号的地位、作用和特征.利用生产函数的理论,分析了我国铁路通信信号的经济效益并建立了数学模型.定量地计算了铁路通信信号对铁路运输总产值的贡献,提出铁路电务部门是铁路运输中的重要生产部门.
This paper discusses the position, action and characteristic of railway communication and signal, and analyses its economic beneficial results and establishes the mathematcal model based on the theory of productive function. The contribution to the total production of railway transportation is calculated quantitatively. It is presented that we must take railway communication and signal as one of the important part of the production of railway transportation.
