大食物观下中国食物安全的综合评价:基于熵权TOPSIS模型
Comprehensive evaluation of China's food security under the greater food approach:Based on entropy TOPSIS model
摘要
Abstract
In order to investigate the development level of China's food security,this study constructed a theoretical and logical analytical framework for food security based on the supply system of the whole industrial chain under the greater food approach,formed a scientific and comprehensive evaluation index system of China's food security in six key dimensions,such as availability,accessibility,reachability,controllability,substitutability and sustainability,and utilized the entropy-weighted TOPSIS model to evaluate China's food security level from 2010 to 2022.The results show that:1)The overall development level of China's food security under the greater food approach has been steadily increasing,and the process of change can be divided into two stages,which are slow increasing stage and rapid increasing stage.It shows a trend from unbalanced development to balanced development.2)From the point of view of the structural evolution of China's food security,it is discovered that the levels of the above six dimensions are all showing an overall increasing trend.The level of availability is lower than that of food security in recent years,which has restricted food production;the levels of both accessibility and reachability have grown at similar rate to the food security level,which contributes to China's food security in general;the level of controllability has risen the most,becoming the main pulling force for China's food security;the level of substitutability shows a year-on-year upward trend,which is basically in line with the trend of changes in the level of food security and has become a key factor in maintaining and improving China's food security;the sustainability level has exhibited a"U"-shaped upward trend,particularly since 2020,when it has emerged as the primary driving force behind the enhancement of China's food security standards.In conclusion,it is necessary to focus on strengthening the protection of arable land and the development and utilization of diversified resources,stabilizing the supply of agricultural labour,upgrading the quality of agricultural labour,optimizing the structure of agricultural labour and efficiently utilizing the resources of the international market.关键词
