Changes of total factor productivity，technological progress and efficiency in Chinese banana industry

In this paper，based on DEA -Malmquist index method，we calculated the total factor productivity （TFP）of China and the 5 major banana producing areas in 2003-2014，and decomposed it into technological progress and technological efficiency. The results showed that the TFP growth rate of banana industry in China was 1.3%，which was mainly due to the technological progres，which was 2.6%，and the pure technological efficiency and scale efficiency declined，which were -0.1% and -1.2%. The improvement of total factor productivity of banana industry in China was mainly due to the technological progress，and it was the extension and application of new technologied，such as cultivation of new banana varieties，high quality cultivation management，technology of saving water and fertilizer，and no injury harvest and so on. Pure technological efficiency and scale efficiency of banana production was negative，it indicated that our banana plantation management level was not high，to achieve economy scale effect through convergence and integration still need to practice，banana growers should promote technology progress at the same time，and promote the banana industry scale and management level.
