Study on the Dynamic Efficiency of Listed Household Appliances Companies Based on the Malmquist-DEA Model

摘要

Based on data from16 listed household appliances companies, we use the Malmquist-DEA model to estimate the dynamic change of the total factor productivity (TFP) in the household appliance industry from 2002 to 2006, and analyze the scale efficiency and the input congestion level of household appliance industry. The results show that the TFP of household appliance industry was improved slightly, and the technical progress was obvious, but the pure technical efficiency and the scale efficiency were declining, and the input congestion degree was higher.
