Abstract:

In the present study, the yield-increasing effect of grain total factor productivity at provincial level in China (Hong Kong, Macao, Taiwan excluded) from 2008 to 2018 was empirically measured based on the dynamic spatial Durbin model. It was shown that the grain total factor productivity increased steadily from 1.024 in 2008 to 1.156 in 2018 in China, and the number of high-efficiency production regions increased from 0 in 2008 to 11 in 2018, but the “Matthew effect” emerged in the process of improvement. The rise in grain total factor productivity could significantly contribute to the increase of grain yield, and its effect was second to the sown area of grains. At the national level, the increase in grain total factor productivity in the neighboring region brought a significant positive spillover effect to the local region. From the spatial structure, the spillover effect of grain total factor productivity showed significant spatial heterogeneity, with a significant negative spillover effect in the central China, a positive spillover effect in west China, and no significant spillover effect in east China.

Key words: food security, spillover effect, dynamic spatial model
