中国食物安全水平的区域差异及关键驱动因素研究
REGIONAL DISPARITIES AND KEY DRIVERS OF FOOD SECURITY IN CHINA
摘要
Abstract
Coordinated development is a core technique for ensuring food security.This study developed a comprehensive food security assessment paradigm for China,based on six important dimensions:affordability,controllability,substitutability,accessibility,availability,and sustainability.Employing the entropy method,it estimated China's food security status from 2010 to 2022.Subsequently,it analyzed the spatial origins and temporal evolution of regional food security disparities by employing the Dagum Gini coefficient and Kernel density estimation techniques.And to further,it examined the dynamics driving these disparities with the Kaya identity and logarithmic mean divisia index(LMDI)factor decomposition method.The results listed four key findings:(1)China's overall food security level had consistently improved over the examined period and remained relatively high,however,regional disparities persist.Spatially,food security levels decline in the order:Huang-Huai-Hai Region-Northeast Region-Middle and Lower Reaches of the Yangtze River Region-Other Regions.(2)In terms of relative disparities,intranational differences in food security had generally narrowed,while intraregional differences within the Northeast,Huang-Huai-Hai,Middle and Lower Reaches of the Yangtze River,and other regions had expanded.Interregional disparities,however,had shown a gradual and fluctuating decrease,indicating a convergence in the food security levels among regions.And interregional differences remained the main contributor to overall spatial disparities in food security.(3)Concerning absolute disparities,the internal absolute differences within China,the Northeast Region,and other regions had slightly expanded,whereas those in the Huang-Huai-Hai and the Middle and Lower Yangtze River Regions had decreased.(4)Examining the driving factors behind food security trends,the findings revealed that economic growth,industrial structure,land use intensity,and resource endowment had collectively contributed to variations in food security levels across China and its four main regions.Notably,economic growth and resource endowment showed significant positive impacts,while the industrial structure and land use intensity had shown negative,though gradually weakening,effects on food security.Therefore,to further enhance China's food security,this study suggests an"all-encompassing approach to food"that integrates innovative concepts,emphasizing strengthened arable land protection,technological advancement,and supporting coordinated regional development.关键词
