摘要20世纪90年代中期，日本政府启动了一系列的规制改革。日本城市燃气行业由各种规模的私营和非私营企业组成。许多先前的研究发现，放松管制导致生产率的提高。我们通过分析放松管制，私有化，和其他方面的一个受管制的行业，使用独特的公司层面的数据来扩展文献。本研究以生产率作为衡量指标来评估放松管制改革的效果。利用1993 - 2004年205家企业的数据，我们发现，放松管制的效果取决于企业规模。竞争压力有助于提高生产力。放松对商业客户的天然气销售管制是提高生产力的最重要因素。
Abstract The Japanese government initiated a series of regulatory reforms in the mid-1990s. The Japanese urban gas industry consists of various sized private and non-private firms. Numerous previous studies find that deregulation leads to productivity improvements. We extend the literature by analyzing deregulation, privatization, and other aspects of a regulated industry using unique firm level data. This study measures productivity to evaluate the effect of the deregulation reform. Using data from 205 firms from 1993 to 2004, we find that the deregulation effect differs depending on firm size. Competitive pressure contributes to advanced productivity. The deregulation of gas sales to commercial customers is the most important factor for advancing productivity.
