Robustness has gathered in the last decades the interest of many specialists in the field of structures and infrastructures engineering.Such a characteristics can be seen as a specific property of a structure which is able to preserve the same,or a similar,level of performance even if local failures occur (Starossek &Haberland 2011,Frangopol et al.2012).

本文基于甘肃省1240个农户的两期面板微观数据,利用西北生态严重退化区休耕试点政策作为准实验,采用双重差分法识别农地休耕对农户收入的影响,并进一步探究这一影响的作用机制与异质性。研究发现,农地休耕可使农户年总收入提高0.4978万元,增幅为10.35%,这一效应,在剔除休耕补贴后依然存在,但在不同收入水平的农户群体间存在差异,突出表现为“益富不益贫”的特点。作用机制分析表明,农地休耕主要通过提高转移性收入的直接作用和促进非农就业由此提高非农收入的间接作用两条途径来促进农户增收,且以增加的非农收入贡献度最大
