Abstract:

As one of the major path to realize agricultural modernization, protected vegetables have been rapidly developed in China due to its good economic and social benefits. In order to comprehend the national production efficiency of protected vegetables, figure out the reasons of high or low production efficiency at different regions, and realize the macroeconomic regulation and control of vegetable production resources allocation, we adopted super efficiency DEA and Malmquist index method to ecalculate from static and dynamic perspective the efficiency of protected vegetables production in China. The results were obtained as follows: ① There were 23 DEA efficiency among all 63 DMUs in 2011-2013, when the DEA inefficiency proportion was 63.49% and problem about the excessive investments on protected vegetables was serious. ② Protected vegetables TFP(total factor productivity) in China increased by 0.8% in 2011-2013, technical efficiency was the power of TFP growth, technological advances had the negative effect on TFP growth. In order to improve the production efficiency of protected vegetables, the scientific research and achievement transformation of protected vegetables should be strengthened, the agricultural technology extension should be further promoted, and attention should be paid to learning and communication, so as to improve the production efficiency of protected vegetables.

Key words: super efficiency DEA, Malmquist index, technical efficiency, technological progress, protected vegetables
