俄乌冲突背景下农业推广服务对农场韧性的作用
Agricultural extension services for farm resilience in Russian–Ukrainian Conflict
摘要
We analyse how agricultural extension services affect farm resilience using the Post-Russian Invasion Survey of Smallholder Farmers in Ukraine for 2022–3. Farm household resilience is measured using the Resilience Capacity Index (RCI), constructed from Adaptive Capacity (AC), Assets (AST), Social Safety Nets (SSN), and Sensitivity (S). To address the heterogeneity problem, Latent Profile Analysis (LPA) defines homogenous resilience profiles. The manuscript also examines a causal relationship by incorporating treatment effects into latent analysis. The results reveal that extension service receivers experience higher levels of AST and SSN. The extension service has a positive effect on RCI levels.
中文摘要
我们利用2022-2023年乌克兰小农户战后入侵调查数据，分析农业推广服务如何影响农场韧性。农场家庭韧性通过韧性能力指数（RCI）衡量，该指数由适应能力（AC）、资产（AST）、社会安全网（SSN）和敏感性（S）构成。为应对异质性问题，采用潜在剖面分析（LPA）定义同质韧性剖面。本文还通过将处理效应纳入潜在分析，考察因果关系。结果显示，接受推广服务的农户在AST和SSN方面水平更高。推广服务对RCI水平具有正向影响。
