While comparative research on nonprofit organizations has made much progress since the launch of the Johns Hopkins Comparative Nonprofit Sector Project in 1990, there now seems to be a loss of momentum. Some of the reasons for this have to do with aspects of definition, classification, and aggregation that can be corrected. The main issue, however, is the lack of progress in advancing comparative nonprofit sector theories beyond the social origins theory. To remedy this, the essay proposes four ways forward as part of a new research agenda.

非营利组织和部门的比较研究：回顾与展望

尽管自 1990 年约翰·霍普金斯大学比较非营利部门项目启动以来，非营利组织的比较研究取得了很大进展，但现在似乎失去了动力。造成这种情况的部分原因与可以纠正的定义、分类和聚合方面有关。然而，主要问题是在推进社会起源理论之外的比较非营利部门理论方面缺乏进展。为了解决这个问题，本文提出了四种前进方法，作为新研究议程的一部分。
