Evaluation of The Level of Digital Economy Empowering the Safety of China's Major Food Crops
Based on the empirical analysis of the production and consumption data of the four major staple foods from 2003 to 2022,this study found that the level of food security in China has continued to rise,shifting from a sin-gle support for structural security to a pattern of supply,economy,structure,and ecological security jointly supporting food security.However,the security levels of the four major staple crops are in the order of rice＞corn＞wheat＞soy-beans.In addition,there is a certain correlation between food crop security and the development of the digital econo-my in both regional and crop dimensions.To verify the correlation,this paper takes the level of digital economy devel-opment as the core explanatory variable,and food security and the four major staple crops as the explained variables.Control variables are determined within the four sectors,and digital industrialization is used as a replacement variable for econometric analysis.The results show that digital economy can improve China's food security level,but the em-powerment degree of the four major staple crops security levels is different.Soybean security mainly relies on govern-ment guarantees,while rice security is guaranteed by government-led effective market that plays a role,and wheat and corn security is mainly guaranteed by the effective market.Due to the negative correlation between economic de-velopment level and food security,the northeast,central,and western regions will shoulder more responsibility for food security.By paying attention to the differences in food crop security levels,optimizing the planting structure of food crops,formulating differentiated safeguard measures,and increasing the application of digital technology in the entire food process,China's food security level will enter a track of mutual progress of quality and quantity.
