Production efficiency change and convergence analysis of japonica rice in China LIU De-juan

The total factor input-output efficiencies of japonica rice production in our country were deduced by analyzing the output-input panel data (2001-2012) of 12 provinces of japonica rice main production areas. The results showed that, from 2001 to 2012, the average rate of growth of the total factor productivity (TFP) was -2.3% and the technological progress was -2.2%. The decline of technical progress was the main cause of the decrease of TFP. Moreover, distinctions existed among the TFPs of these provinces, while the TFPs of Heilongjiang and Jiangsu Provinces were higher than that of other provinces. Further convergence test indicated that the TFP of main production areas had convergence trend.
