The objective of this study is to analyze the total factor productivity (TFP) of soybean in China. The present study used a multilateral index to measure regional soybean TFP and analyzed the factors affecting TFP. This study used province-level pooled data from 2004 to 2020. The results show that the trend of soybean TFP since 2014 seems to have accelerated. However, the contribution rate of conventional production factors has been remarkably high with the increase in soybean production. In addition, the improvement in water supply development and the reduction of the number of disaster areas contributed to the increase in TFP.
