韧性能力对我国西部农村家庭食品支出和膳食多样性的影响分析

doi:10.1016/j.jia.2023.12.010

摘要/Abstract

摘要： 更具韧性的农户生计系统对于改善脆弱家庭食品安全状况和膳食决策具有重要影响。本研究利用多指标多因素模型（MIMIC）量化分析了我国西部地区农村家庭的韧性能力，并分析了韧性能力的三个维度（抗逆能力、恢复能力、因应与演进能力）对韧性能力的贡献，探讨了食品支出、膳食多样性与韧性能力的关联性。结果显示，尽管存在区域异质性，但农户韧性能力指数（RCI）在2015年至2021年间持续增长。具有较高韧性能力指数的家庭，呈现出与家庭食品支出增加和膳食选择多样化的正相关关系，其原因可能由于具有韧性能力的家庭，其处理风险和冲击的能力更强，能够将更多的钱用于食品支出，而不是为不确定性而储蓄。因此，政策制定者应支持农户采用更加有效的风险管理策略，提高农户生计系统的韧性水平，这对预防与饮食相关的人力资本损失将产生积极的溢出影响。

Abstract:

A more resilient livelihood is increasingly recognized as an efficient way to improve vulnerable households’ food security and optimize their dietary decisions. This study quantifies rural household resilience in western China, identifies the three pillars (absorptive capacity, adaptive capacity, and transformative capacity) contribution to resilience, and then establishes the estimated Resilience Capacity Index (RCI) linked with food security and dietary diversity supported by the multiple indicator multiple cause (MIMIC) model. Results show that, despite geographical heterogeneity, the RCI consistently increased from 2015 to 2021. Households with a higher RCI inheriting better capacity to deal with risk and shocks are significantly and positively correlated with increasing food expenditure and diversifying food choices. It can be because resilient households will allocate more money to food expenditure instead of saving for livelihood uncertainty. Thus, policymakers can provide more incentives for rural households to adopt more dynamic and effective risk management strategies. This, in turn, could yield positive spillover effects by preventing human capital loss associated with dietary-related chronic diseases and mortality.
