Abstract

This paper explores the impacts of the evolution of the dietary structure of the population on national food security using the food self-sufficiency rate under various statistical dimensions and simulate various food security scenarios for China in the medium- and long-term future. This study indicates that China’s rapid economic and social development and the continuous improvement in people’s living standards appears to be declining in the food self-sufficiency rate. The analysis regarding the factors influencing the food self-sufficiency rate revealed that the improved dietary structure, involving an increase in animal-based food product consumption, has led to a decrease in China’s food self-sufficiency rate. It concludes that the dietary structure is likely to continue to move toward increased consumption of animal-based food products in China for the future. The research results will assist decision-makers in formulating scientific food self-sufficiency rate targets and food security strategies

This study mainly focuses on the dynamic evaluation of food security and the grain self-sufficiency rate in China, the mechanism whereby the dietary structure evolution influences the grain self-sufficiency rate, predictions of medium- and long-term future food demand based on the evolution of the dietary structure, and regulatory strategies and schemes related to food security in response to the evolution of the dietary structure

Summary

Introduction

China is promoting the strategy of rural revitalization, and it is significant to ensure national food security. Under the uncertain situation of the food market caused by the COVID-19, it is critical for rural revitalization to ensure adequate food and essential agricultural products. Some food-exporting countries have taken measures to restrict exports to ensure their food supply in response to the potential economic stagnation and decline in production caused by the spread of the epidemic, raising concerns about the world’s food supply. In this context, it is urgent and essential to analyze the changing dietary structure and its impact on China’s change of food self-sufficiency
