摘要

2002 年，中国煤电批发行业实行了一系列市场改革。紧接着的一段时期，煤电行业极不稳定，人们普遍认为许多改革措施并未完全实施。然而，研究人员一致发现，这些改革为发电厂带来了效率收益。通过使用新的实物数据和匹配的财务数据，而不仅仅是财务数据，我发现没有证据表明电厂层面的效率提高了。我还发现，在此期间，生产率总体上出现了大幅下降。在这两种情况下，任何可衡量的收益都主要归因于投入和产出的价格波动。

Missing data and the effects of market deregulation: Evidence from Chinese coal power

A series of market reforms were introduced in 2002 in the Chinese wholesale coal power sector. The period immediately after extremely volatile for this industry, and it is generally accepted that many of the reforms were not fully enacted. Yet, researchers consistently find that these reforms resulted in efficiency gains for power plants. Using new physical and matched financial data, as opposed to only financial data, I find no evidence that there were efficiency gains at the plant-level. I also find that in the aggregate there were large productivity declines over this period. Any measurable gains in either case are mainly due to input and output price fluctuations.

期刊介绍： The IJIO is an international venture that aims at full coverage of theoretical and empirical questions in industrial organization. This includes classic questions of strategic behavior and market structure. The journal also seeks to publish articles dealing with technological change, internal organization of firms, regulation, antitrust and productivity analysis. We recognize the need to allow for diversity of perspectives and research styles in industrial organization and we encourage submissions in theoretical work, empirical work, and case studies. The journal will also occasionally publish symposia on topical issues.
