This paper investigates how the characteristics of university laboratories influence the propensity of Ph.D. students to entrepreneurship, and thus, contribute to the transfer of academic knowledge to society. As determinants of Ph.D. entrepreneurship, we focus on the lab scientific and social capital as well as on the business experience that Ph.D. students acquire during their training period. The empirical exercise is based on questionnaire survey data of 5266 Ph.D. students in Italian universities in all subject areas. First, we find that 6.7% of the Ph.D. graduates engage in startup activities, and thus, Ph.D. training seems to contribute to knowledge transfer through entrepreneurship. Second, Ph.D. entrepreneurship is driven by business experience, in the forms of industry collaboration and industrially applicable research projects, during their training period. Third, the lab scientific capital is negatively associated with Ph.D. entrepreneurship, suggesting a conflict between scientific excellence and entrepreneurship, but this effect is mitigated if students acquire business experience. Fourth, the lab social capital increases the chance of startup when students have business experience. We further investigate the effects of lab environment by distinguishing between startups that are based on university research and startups that are not, finding different determinants.

本文研究了大学实验室的特征如何影响博士学位的倾向。学生创业，从而为向社会传播学术知识做出了贡献。作为博士学位的决定因素。企业家精神，我们专注于实验室的科学和社会资本以及博士所拥有的商业经验。学生在培训期间获得。实证研究基于5266名博士的问卷调查数据。所有学科领域的意大利大学的学生。首先，我们发现博士学位占6.7％。毕业生从事创业活动，因此有博士学位。培训似乎有助于通过企业家精神进行知识转移。二，博士 企业家精神是由业务经验驱动的，包括行业合作和行业适用的研究项目，在他们的训练期间。第三，实验室科学资本与博士学位负相关。企业家精神，这表明科学卓越与企业家精神之间存在冲突，但如果学生获得商业经验，这种影响就会减轻。第四，当学生具有业务经验时，实验室的社会资本增加了启动的机会。我们通过区分基于大学研究的初创公司和非大学研究的初创公司，找出不同的决定因素，从而进一步研究实验室环境的影响。当学生具有业务经验时，实验室的社会资本增加了启动的机会。我们通过区分基于大学研究的初创公司和非大学研究的初创公司，找出不同的决定因素，从而进一步研究实验室环境的影响。当学生具有业务经验时，实验室的社会资本增加了启动的机会。我们通过区分基于大学研究的初创公司和非大学研究的初创公司，找出不同的决定因素，从而进一步研究实验室环境的影响。
