摘　　要：沃特森的自然垄断理论表明,严重的供不应求和独家经营规模不经济两种状况同时出现是自然垄断行业市场主体多元化的前提条件。对我国铁路运输业的供需状况进行考察,发现整个行业处于严重的供不应求状态;对在我国铁路运输业中几乎处于独家垄断经营的国铁的规模经济状况进行分析,发现其出现了严重的规模不经济现象。综合考虑上述两种情况,我国铁路运输业已经具备了进行市场主体多元化改革的条件。The natural monopoly theory of Waterson indicates that the prerequisite for natural monopoly industry to realize the diversification of suppliers is the conjunction of seriously tight market and the sole supplier＇ s diseconomies of scale. To examine the supply and demand situation of Chinese railway transport industry, it can be found the supply of the industry seriously lags behind the demand. To analyses the situation of scale economy of national railways which is close to a monopoly in the industry, it can be found that serious diseconomies of scale occurs in national railways. In view of the above two situations, the condition of suppliers diversification reform for Chinese railway transport industry is available.
