Abstract

Using DEA three-stage model and Malmquist index decomposition method, The Total Factor Productivity (TFP) of 28 provinces and cities in China during the period of 1987-2008 are measured and decomposed, the change trends and regional differences of TFP are also analyzed. At the same time, Kernel density distribution method is used to analyze the effects of input factors and TFP on regional economic gap. The results show that environmental factors have a great effect on the measurement of efficiency; therefore DEA three-stage model enhances scientificness of efficiency evaluation and comparability between the provinces. Technical efficiency is the main factor impacting TFP change, and spatial difference of TFP change is quite large, however the difference shows a narrowing trend. Evenly spatial distribution of input factors makes a greater contribution to narrow China’s regional economic gap.

Key words

TFP / DEA three-stage model / Malmquist index / regional economic gap
