打破供应链壁垒：女性所有中小企业采购培训的实验证据
Breaking into Supply Chains: Experimental Evidence on Procurement Training for Women-Owned SMEs
摘要
Women-owned-or-led small and medium-sized enterprises (WSMEs) are underrepresented in public and corporate supply chains worldwide. There is growing interest in promoting SMEs’ and WSMEs’ integration into value chains, but limited causal evidence whether interventions to support their participation in procurement are effective. This paper conducts a phased randomized controlled trial to estimate the impacts of corporate procurement training for WSMEs in Colombia. The program increases procurement knowledge and readiness, resulting in a ten percentage point increase in registrations to corporate portals, and an eight percentage point increase in the likelihood of submitting a bid. Impacts on winning bids are concentrated in WSMEs with prior procurement knowledge or experience, whose probability of winning a contract increases by eight to nine percentage points. These impacts are approximately twenty percent of the control means. More broadly, the paper illustrates how complier-weighted treatment effects can be used to evaluate programs delivered through a funnel-shaped participation process, common in private sector development interventions.
中文摘要
女性所有或领导的中小企业（WSMEs）在全球公共和企业供应链中代表性不足。人们日益关注促进中小企业及WSMEs融入价值链，但关于支持其参与采购的干预措施是否有效的因果证据有限。本文开展了一项分阶段随机对照试验，以评估哥伦比亚WSMEs企业采购培训的影响。该项目提高了采购知识和准备度，使企业门户网站注册率提高10个百分点，提交投标的可能性提高8个百分点。对中标的影响集中在事先具备采购知识或经验的WSMEs中，其获得合同的概率提高8至9个百分点。这些影响约为对照组均值的20%。更广泛而言，本文说明了如何使用依从者加权处理效应来评估通过漏斗式参与过程实施的项目，这种过程在私营部门发展干预中很常见。
