In this paper we use the conventional Data Envelopment Analysis Malmquist approach to estimate the Malmquist index, efficiency change and technical change in China for the period of 2000-2017. The two methods of calculating the capital stock are compared, and the data of the capital stock calculated by the two methods are used to estimate. Furthermore, the results are analyzed by regions. The results show that China's total factor productivity increased by an average of 1.2% per year from 2000 to 2017, and the technical change increased by an average of 1.9% per year. The technical change is the most important driving force for the increase in total factor productivity. The total factor productivity growth in eastern regions is the highest at 2.7%, followed by 0.6% in the northeastern regions, 0.5% in the centre regions, and 0.3% in the western regions. The growth in total factor productivity in western regions is the least.
