Abstract:

In order to measure China’s (excluding Hongkong, Macao, Taiwan) agricultural total factor productivity in a standard way and identify the regional differences, the input variables of land, labor and intermediate inputs under the framework of input-output unity were clarified, and the agricultural capital stock of provincial-level regions were estimated by using the minimum deviation method. The SFA-KLH model, suitable for China’s agricultural production, were introduced to measure the growth of agricultural total factor productivity since the implementation of reform and open policy, and the trend sources, spatial and regional distribution of agricultural total factor productivity from 1978 to 2020 were also discussed. It was found that the China’s agricultural total factor productivity showed an overall fluctuating growth trend during 1978-2020. But, after 2006, China’s agricultural total factor productivity showed a slowing down and stable growth trend. The average annual growth rate of China’s agricultural total factor productivity measured by SFA-KLH was 2.27%, and technical progress was the main growth source. There was spatial difference of agricultural total factor productivity, and the growth of agricultural total factor productivity decreased as central>east>west. On the whole, there was no absolute convergence of agricultural total factor productivity in China, but the conditional convergence did exist, and different provincial-level regions had different convergence rates.

Key words: agricultural total factor productivity, capital stock, spatial distribution
