The role of urbanization in agricultural development has always attracted wide attention of researchers. However, a consensus on the impact of urbanization on food security has not been reached. Based on the panel data of 31 provinces in China’s mainland from 2000 to 2016, this study used the mediation effect model to explore the impacting mechanism of urbanization on food security, and carried out an empirical analysis for the different types of grain supply-demand balance areas. The results show that urbanization has a significant positive impact on food security in terms of national level. With regard to the effects of the mediating factors, land and labor are negative, while agricultural technology is positive and most significant. Urbanization has a significant positive impact on food security in the main grain producing areas and the supply-demand balanced areas, and the positive intermediary effect of agricultural technology is far greater than the negative effects of both land and labor. However, a significant negative impact exists in the grain importing areas, and the impacting factors include land, labor, and technology, but the negative intermediary effect of land is the largest. To ensure food security, we should focus on using agricultural land intensively, improving the quality of labor force, and strengthening investment in agricultural technology.
