摘要:
Data envelopment analysis (DEA) measures the relative efficiency of peer units when multiple outputs and inputs are present. DEA-based Malmquist productivity index measures the technical and productivity changes over time. The current study extends the Malmquist productivity index into a non-radial index where the decision maker's preference over performance improvement can be incorporated. The non-radial Malmquist productivity index eliminates possible inefficiency represented by the non-zero slacks. The method is applied to measure the productivity change of three Chinese major industries: Textiles, Chemicals and Metallurgicals during four five-year-plan periods. The paper shows how DEA-based Malmquist productivity index can be employed to evaluate the technology and productivity changes resulted from the economic development plans. The paper also shows the importance of using the non-radial Malmquist productivity index. (C) 2002 Elsevier Science B.V. All rights reserved.
