Estimation and Decomposition of Total Factors Productivity in Zhejiang Province : A Study Based on DEA-Malmquist Productivity Index Approach

This paper uses DEA-Malmquist productivity index approach to estimate and decompose total factors productivity(TFP) of 11 regions in Zhejiang Province.The estimating result shows that TFP of all regions grow fast from the 8th Five-Year Plan to the 9th Five-Year Plan,while TFP of some regions declines remarkably during the 10th Five-Year Plan.Further decomposing results suggest that technological efficiency change is characterized in convergence and has little effect on TFP,while technology changes in similar fashion with TFP,therefore it is identified as a main influencing factor in TFP change.
