At a time of critical talent shortages and environmental challenges, it is necessary to increase understanding of how green employer certification (GEC), as an ethical market signal, affects job seekers' perceptions. This study examines whether the relationship between GEC in recruitment advertisements and organizational attractiveness is mediated by firms' perceived prestige and person-organization (PO) fit and if it varies according to firm ownership (i.e., investor-owned vs. member-owned). Results from a controlled online experiment firstly show that the communication of GEC has an indirect positive influence on organizational attractiveness via the mediating effects of perceived prestige and perceived PO fit. Secondly, depending upon firm ownership, people interpret the same certification differently: the communication of GEC thus has an indirect influence on organizational attractiveness and significantly improves firms' perceived prestige and PO fit among member-owned firms but not among investor-owned firms. Hence, practitioners should consider the value of including environmental certification in their recruitment advertising strategy while considering the issue of firm ownership.

绿色认证与组织吸引力：企业所有权的调节作用

在严重的人才短缺和环境挑战之际，有必要加深对作为道德市场信号的绿色雇主认证 (GEC) 如何影响求职者的看法的理解。本研究考察了招聘广告中的 GEC 与组织吸引力之间的关系是否由公司感知的声望和个人组织 (PO) 契合度来调节，以及它是否因公司所有权（即投资者所有与成员所有）而异。一项对照在线实验的结果首先表明，GEC 的沟通通过感知声望和感知 PO 契合度的中介效应对组织吸引力产生间接的正向影响。其次，根据公司所有权的不同，人们对相同的认证有不同的解释：因此，GEC 的沟通对组织吸引力有间接影响，并显着提高了公司在成员拥有的公司中的感知声望和 PO 契合度，但在投资者拥有的公司中却没有。因此，从业者在考虑公司所有权问题的同时，应考虑将环境认证纳入其招聘广告策略的价值。
