中文摘要：

非营利组织的失信行为严重影响了非营利组织在公众心目中的神圣形象，打击了公众对非营利组织的信心，也严重影响到了非营利组织的长远发展。因此，非营利组织公信力的研究具有重要的意义。近年来，国内学者关于非营利组织公信力的研究成果较丰富，主要集中于公信力的内涵、失信的表现及成因、公信力的评估、公信力提升路径等四个方面。但是，学者的研究还需在基础性理论、实效性和研究方法上有待改进。

英文摘要：

The dishonest behavior of the non-profit organization（NPO） seriously affects the sacred im- age of the NPO in the public. It injures the public confidence in the NPO and is also harmful to the long-term development of the NPO. Therefore, the study on the credibility of the NPO is of great sig- nificance. This paper reviews the abundant related researches made in recent years from four aspects, namely the meaning of the credibility of the NPO, its evaluation criteria, the causes of incredibility, the measures for improving the credibility of the NPO, etc. It also points out that the researchers should be more focused on the fundamental theories, effectiveness and approaches of the research in the future.
