基于DPSIR-TOPSIS模型的新时代粮食安全可持续性发展评价体系构建OA

To further consolidate food security and explore the development of food security in the new era,a evaluation index system for the development level of food security was constructed based on the DPSIR model.Correlation analysis and entropy weighting method were employed to optimize the relevant indicators,followed by the application of the TOPSIS method to empirically analyze the development level of China's food security from 2017 to 2022.The research results indicate that there are numerous and varied factors influencing food security,and the development level of food security exhibits significant fluctuations.From a categorical indicator perspective,the driving force is a key factor influencing food security in the new era.Further advancement in aspects such as grain reserve systems,food supply systems,sustainable agricultural production techniques,and circular economy is proposed to promote the development of food security in the new era.The DPSIR-TOPSIS model demonstrates strong practicality in evaluating the development level of food security in the new era,contributing to the enhancement of sustainable development in food security.
