The contribution to human and social capital accumulation is one of the most important socio-economic benefits of public investment in Research Infrastructures. Sure enough, these large scientific enterprises are exceptional incubators of human and social capital, especially for early-career researchers who have the opportunity to gain new skills and expand their network of contacts in highly prestigious and challenging workplaces. This paper explores the contribution of spending a period of study and/or work at the Large Hadron Collider of CERN to the expected future lifelong salary of early-career researchers. Previous studies are here extended by using three sources of data: primary data collected through a survey to CERN Alumni, a survey to team leaders who supervised early-career researchers at CERN, and secondary data salary information. Findings show that an experience-based learning process at CERN is instrumental in developing skills that are needed by the economy and reveal an expected salary premium between 5% and 11%. Such human capital effect seems more important than a pure networking and reputational effect.

研究基础设施内的人力和社会资本积累：以欧洲核子研究中心为例

对人力和社会资本积累的贡献是研究基础设施公共投资最重要的社会经济效益之一。果然，这些大型科学企业是人力和社会资本的杰出孵化器，尤其是对于那些有机会获得新技能并在享有盛誉和具有挑战性的工作场所扩大人脉网络的早期研究人员而言。本文探讨了在欧洲核子研究中心的大型强子对撞机上花费一段时间的学习和/或工作对早期职业研究人员的预期未来终生工资的贡献。以前的研究在这里通过使用三个数据源进行了扩展：通过对 CERN 校友的调查收集的原始数据、对在 CERN 监督早期职业研究人员的团队领导者进行的调查，以及辅助数据工资信息。调查结果表明，欧洲核子研究中心的基于经验的学习过程有助于培养经济所需的技能，并显示出 5% 到 11% 的预期工资溢价。这种人力资本效应似乎比纯粹的网络和声誉效应更重要。
