Abstract
Briec et al. (2003) Aggregation of directional distance functions and industrial efficiency. J Econ 79:237–261) showed that industrial and structural efficiency are identical in the context of cost aggregation if all firms use the same technology, a single output is produced and constant returns to scale prevail. In this note it is shown that the same is also true if the technology is additive, which is equivalently referred to as independence in production or input non-jointness.
Briec et al. (2003) Aggregation of direction distance functions and industrial efficiency.J Econ 79:237-261）的研究表明，如果所有企业使用相同的技术，生产单一产品，并且规模收益不变，那么在成本聚集的情况下，产业效率和结构效率是相同的。本说明指出，如果技术具有可加性，即生产的独立性或投入的非联合性，则两者也是相同的。
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
