铁路运输业在经济发展中发挥了重要作用,但是铁路运输的紧张局面已成为制约国民经济发展的“瓶颈”,铁路运输企业内部经济效益逐年下降。作者通过对非瓦尔拉均衡模型的分析,就目前铁路运输企业亏损的原因作一初步探讨。
Railway transportation plays an important role in economic development, but the tension of railway transportation has become a “bottleneck” restricting the development of the national economy. The economic benefits of railway transport enterprises have been declining year by year. Based on the analysis of the non-Walla equilibrium model, the author makes a preliminary study on the reasons for the current loss of railway transport enterprises.
