十年后集团咨询仍使企业受益：来自哥伦比亚汽车零部件企业的实验证据
Group Consulting Continues to Benefit Firms after a Decade: Experimental Evidence from Colombian Auto Parts Firms
摘要
We revisit a randomized experiment that demonstrated the cost-effectiveness of group-based, compared to individual, consulting services for firms in the Colombian auto parts industry using administrative data that now permits following firms for up to a decade. Firms in the group consulting intervention are more likely to survive, have higher employment, and have increased sales and profits by approximately 50%. This longer-term growth appears to in part come through increased exporting, as well as persistent management improvements. Case studies offer insights into underlying mechanisms. The more expensive individual consulting has noisy long-term impacts that are much less cost-effective.
中文摘要
我们重新审视了一项随机实验，该实验通过行政数据展示了哥伦比亚汽车零部件行业中，相较于个体咨询，团体咨询对企业服务的成本效益，如今这些数据允许对企业进行长达十年的追踪。参与团体咨询干预的企业更有可能存活，就业人数更高，销售额和利润约增长50%。这种长期增长部分似乎源于出口增加，以及持续的管理改进。案例研究揭示了背后的机制。成本更高的个体咨询在长期影响上存在噪音，且成本效益远低于团体咨询。
