The productive efficiency analysis of Chinese steel firms: An application of data envelopment analysis.

摘要

Efficiency has become one of the most important factors for the survival and development of Chinese steel firms as the economic and political reforms in China deepen. The Data Envelopment Analysis (DEA), a non-parametric approach to the measurement of efficiency, is applied to the cross-sectional data of 35 of the largest Chinese steel firms to estimate the technical efficiency of these firms in a multi-input/output situation. In this thesis, 6 input and 4 output variables are chosen. The empirical study demonstrates the need to reduce resources consumption, especially the number of employees, and to increase outputs, particularly the profit for the Chinese steel industry to improve its technical efficiency.
