Abstract

A JR is one of several freight and passenger railway companies created in 1987 after Japan National Railway (JNR) was privatized and separated. The authors use econometric techniques to examine total factor productivity (TFP) increases and to analyze how performance has changed among the JRs. The authors also examine whether, before privatization, capital input overcapitalization existed. Privatization raised annual TFP growth by 1.62%, bringing total annual TFP growth to 2.97% after privatization. Privatization has largely corrected the former JNR's over-capitalization.

私有化对生产率和资本调整的影响
JR是1987年日本国家铁路(JNR)私有化和分离后成立的几家货运和客运铁路公司之一。作者使用计量经济学技术检验了全要素生产率(TFP)的增长,并分析了JRs之间的绩效变化。作者还考察了在私有化之前,资本投入是否存在过度资本化。私有化使全要素生产率年增长率提高了1.62%,私有化后全要素生产率年增长率达到2.97%。私有化在很大程度上纠正了前JNR的过度资本化。
