1994 年至 2002 年，使用定向输出距离函数在省级评估了中国工业的两种效率指标。一种是传统的效率衡量标准，仅考虑期望的输出，而另一种则同时考虑期望和非期望的输出。两种衡量标准的比较表明，只有在考虑理想产出的情况下，效率水平才会出现偏差。研究发现，仅考虑理想产出以及同时考虑理想产出和不良产出时，吸引大量外国直接投资的五个沿海省/市的效率最高。然而，忽略不良产出往往会导致山东、四川和河北省的工业效率水平被高估。我们还发现，一个省的产业结构对其效率水平有显着影响。 (C) 2007 Elsevier Ltd. 保留所有权利。
Two efficiency measures of Chinese industry were estimated at the provincial level from 1994 to 2002, using a directional output distance function. One is a traditional efficiency measure that considers only desirable output, while the other considers both desirable and undesirable outputs simultaneously. A comparison of the two measures revealed that efficiency levels are biased only if desirable output is considered. Five coastal provinces/municipalities that have attracted a large amount of foreign direct investment are found to be the most efficient when only desirable output is considered, and also when both desirable and undesirable outputs are considered. However, omitting undesirable output tends to lead to an overestimate of industrial efficiency levels in Shandong, Sichuan, and Hebei provinces. We also found that a province's industrial structure has significant effects on its efficiency levels. (C) 2007 Elsevier Ltd. All rights reserved.
