政府采购中优惠政策计划的影响:来自退伍军人预留项目的证据

The impact of preference programs in public procurement: Evidence from veteran set-asides
Journal of Public Economics · 2026 · Rodrigo Carril、Audrey Guo

中文摘要

退伍军人拥有的企业在美国退伍军人事务部的采购中享有优惠待遇;按采购支出计,该部是规模最大的联邦文职机构。我们研究最高法院2016年的一项裁决,该裁决扩大了此类预留项目的适用范围,并估计其对目标企业和采购结果的影响。该裁决提高了授予因服役致残的退伍军人所拥有小企业的采购订单合同份额。收益既流向了在位供应商,也流向了首次成为退伍军人事务部承包商的企业,其中包括此前已注册但从未赢得联邦合同的企业。我们发现几乎没有证据表明合同授予的竞争发生变化,且对合同执行绩效没有显著影响。结果表明,在进入壁垒相对较低的商业采购市场中,预留项目能够扩大目标企业的准入机会,而政府采购结果未出现可检测到的恶化。

Abstract

Veteran-owned businesses receive preferential treatment in procurement by the U.S. Department of Veterans Affairs, the largest civilian federal agency by procurement spending. We study a 2016 Supreme Court ruling that expanded the scope of these set-asides and estimate its effects on targeted firms and procurement outcomes. The ruling increased the share of purchase order contracts awarded to service-disabled veteran-owned small businesses. Gains accrued both to incumbent vendors and to first-time VA contractors, including firms that had previously registered but had not won federal awards. We find little evidence of changes in competition for awards, and no significant impact on contract execution performance. The results suggest that, in commercial procurement markets with relatively low barriers to entry, set-asides can expand access for targeted firms without detectable deterioration in government procurement outcomes.
