The Impact of Agricultural Science and Technology Innovation on Global Food Supply Chain An Empirical Analysis Based on Panel Data from 68 Food Producing Countries

With the frequent occurrence of geopolitical, economic and military conflicts in the world, the supply chain security of the global food industry chain is facing serious challenges. In this paper, global food supply chain security(FSCS) is divided into two dimensions: food supply chain dependence and food supply chain concentration, based on cross-country panel data of 68 food-producing countries around the world from 2001 to 2021, firstly, to analyze the global food security situation, and then, based on constructing indexes to measure the agricultural scientific and technological innovation, to empirically estimate empirical estimation of the agricultural scientific and technological innovation(ASTI) capacity impact on global food supply chain security. The results of the study show that agricultural science and technology innovation capacity has a negative impact on both food supply chain concentration and food supply chain dependence; on the whole, the improvement of agricultural science and technology innovation capacity can bring about a decrease in global food supply chain concentration and dependence.
