摘要
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。
Aggregation of directional distance functions and industrial efficiency: a note
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.

Specializing in mathematical economic theory, Journal of Economics focuses on microeconomic theory while also publishing papers on macroeconomic topics as well as econometric case studies of general interest. Regular supplementary volumes are devoted to topics of central importance to both modern theoretical research and present economic reality. Fields of interest: applied economic theory and ist empirical testing.Officially cited as: J Econ
