Abstract:

In this work, we used DEA model and Malmquist index method to evaluate the efficiency of input-output and the TFP(total factor productivity) change of the equipment manufacturing industries in Northeast China in the years of 2006 and 2012. The results show that the advantages of the equipment manufacturing industries in Northeast China present a mutually complementary state. Seven industries in Liaoning province are in the stage of the decreasing returns to scale, while six industries in Jilin province and three industries in Heilongjiang province achieve the best returns to scale. During the six years, the TFP changes of the electric equipment manufacturing industries and the special purpose machinery manufacturing industries in Northeast China are the biggest. In addition, the TFP change of the computer, the telecommunication, and other electronic equipment manufacturing industries in Heilongjiang province and the transport equipment manufacturing and general purpose machinery manufacturing industries in Jilin province are significantly higher than the national average. On the basis of the analysis, we give the adjustment values for achieving the best index of input-output level of the equipment manufacturing industries in Northeast China.
