This paper introduces a modified version of the Hansen-gravity model as a framework to estimate the accessibility of higher education (HE) institutions in Italy from equal opportunities perspective. The fundamental assumption underlying gravity models is that accessibility decreases with spatial distance from opportunities. The paper extends the gravity equation to include socio-economic factors influencing the access to HE. The findings reveal differences in response to quality and other institutional characteristics by parental background and gender. Finally, decomposition of overall inequality into spatial and aspatial components reveals both the physical and social distance between groups of students seeking higher education opportunities in the country.

意大利学生流动性和获得高等教育机会不平等的社会经济因素

本文介绍了Hansen引力模型的修改版本，以此为框架从机会均等的角度估计意大利高等教育机构的可及性。引力模型的基本假设是可访问性随与机会的空间距离而减小。本文将引力方程式扩展到包括影响获取HE的社会经济因素。研究结果揭示了父母背景和性别对质量和其他机构特征的反应差异。最后，将整体不平等分解为空间和非空间部分，揭示了在该国寻求高等教育机会的学生群体之间的身体和社会距离。
