中文摘要：

近年来，随着国有企业战略性调整的开展，针对新国企效率的讨论再度升温。对于新国企效率，不同的分析角度往往得出不同的结论。具体来看，以全要素生产率衡量的国有企业技术效率提升显著，但与其他所有制企业的横向比较的研究结果存在分歧；对于新国企的经营效率变化存在有效、无效、悖论三种观点，其成因分析主要从垄断、政府补助等因素展开；以资源配置效率衡量的资源配置有效性同样存在分歧，针对新国企的研究侧重横向比较和全局分析，“双重效率损失”与预算软约束是问题的焦点；综合效率评价考虑了国有企业的社会效率，一致认为国有企业的综合效率是有效的。

英文摘要：

In recent years,along with the strategic adjustment of state-owned enterprises the efficiency new state-owned enterprises （SOE）has been heatedly discussed again. For the new SOEs,different analytical perspectives often come to different conclusions. Specifically,the SOEs applying the measurement of the total factor productivity have a significant rise in technical efficiency,but the study results are different from the study of other ownership enterprises by horizontal comparison. Therefore,people hold three views on the op- crating efficiency changes in new SOEs,considering it valid,invalid or a paradox. The analysis mainly involve monopolies,government subsidies and other factors. As to the effectiveness of resource configuration measured by the allocation efficiency,there exist the similar differences. The studies of new SOEs have been carried out by means of the global analysis and horizontal comparison,which mainly focus on ＂the double efficiency loss＂ and soft budget constraint （SBC）. The comprehensive evaluation of the efficiency of SOE,on the other hand,takes the social efficiency into account,and agrees that the overall efficiency of SOE is effective.
