A Study on the Impact of Agricultural New-quality Productivity on Food Security in China: Based on Mediating Effects

Agricultural new-quality productive capacity is a key driver for enhancing food security and achieving agricultural modernization. Based on panel data from 30 provinces and unicipalities in mainland China from 2013 to 2022, this study constructed a dual fixed-effects and mediation effects model and employed empirical analysis methods to validate the impact of agricultural new-quality productive capacity on food security and its underlying mechanisms. Research results show that developing new high-quality production capacity in agriculture greatly improves food security, but with heterogeneity. In grain-producing regions and eastern regions, the enabling effect of agricultural new-quality productive capacity on food security is more pronounced. The mediating effect suggests that the development level of rural industrial chains and supply chains, as well as digital agriculture, play a mediating role in the process by which agricultural new-quality productive capacity promotes food security.
