摘要

本文考察了赫芬达尔-赫希曼指数(HHI)是否为企业集中度的可靠决策工具。考虑了该指数的统计特性，以便改进该指数的统计决策。对卫生保健指数统计特征的误用助长了对该指数的可疑使用和应用。它也限制了它的潜在用途。了解HHI的统计性质揭示了这个指数比迄今为止所知的更多。

The Herfindahl-Hirschman Index as a decision guide to business concentration: A statistical exploration

This article examines whether the Herfindahl-Hirschman Index (HHI) is a reliable decision-making tool of business concentration. The statistical properties of the index are considered in order to facilitate an improved statistical decision-making with the index. A misinformed application of the HHI as to its statistical characteristics has encouraged questionable uses and applications of the index. It has also limited its potential uses. Understanding the statistical nature of the HHI reveals that there is more to this index than known heretofore.

期刊介绍： The Journal of Economic and Social Measurement (JESM) is a quarterly journal that is concerned with the investigation of all aspects of production, distribution and use of economic and other societal statistical data, and with the use of computers in that context. JESM publishes articles that consider the statistical methodology of economic and social science measurements. It is concerned with the methods and problems of data distribution, including the design and implementation of data base systems and, more generally, computer software and hardware for distributing and accessing statistical data files. Its focus on computer software also includes the valuation of algorithms and their implementation, assessing the degree to which particular algorithms may yield more or less accurate computed results. It addresses the technical and even legal problems of the collection and use of data, legislation and administrative actions affecting government produced or distributed data files, and similar topics. The journal serves as a forum for the exchange of information and views between data producers and users. In addition, it considers the various uses to which statistical data may be put, particularly to the degree that these uses illustrate or affect the properties of the data. The data considered in JESM are usually economic or social, as mentioned, but this is not a requirement; the editorial policies of JESM do not place a priori restrictions upon the data that might be considered within individual articles. Furthermore, there are no limitations concerning the source of the data.
