铁路运输投资与折旧关系的研究

Research on the Relation Between Investment and Depreciation in China Railway Transport Enterpises

通过对铁路运输经济增长与投资的理论分析，建立了铁路运输投资与折旧的基本测算模型。并且运用１９５０至１９９３年的实际数据对铁路运输业投资与折旧的关系进行了定量分析且提出了＂九五＂期间折旧占铁路投资的比重。

After analysing the relation between the growth of economy and the investment in railway transport, a model to relate the invesment and the depreciation in railway transport enterprises has been established and the actual data from 1950 to 1993 is applied to analyse the model quantitatively. The proportion of depreciation in the railway investment in the period of the nineth five-year plan has been established.
