[目的/意义]科学数据和模型公开共享已成为知识创新活动和学术交流深入发展的共同需求，但少有研究人文社会科学数据共享的影响机制，因此本文探究人文社会科学数据共享意愿影响因素，具有丰富的理论意义和现实意义。[方法/过程]基于同辈压力理论，将影响人文社会科学数据共享的几种因素分为内在压力和外在压力，构建人文社会科学数据共享意愿影响因素模型，进而通过调查问卷数据进行实证分析。[结果/结论]人际信任、互利互惠、态度、团体氛围、团体制度五个变量对科研人员数据共享意愿产生正向影响，感知风险对科研人员共享意愿产生反向影响，科研人员的共享意愿对共享行为产生正向影响。

[Purpose/significance] The open sharing of scientific data and models has become a common need for the in-depth development of knowledge innovation activities and academic exchanges, but few studies have studied the impact mechanism of data sharing in humanities and social sciences. Therefore, this article explores the influencing factors of humanities and social sciences data sharing willingness, which has rich theoretical and practical significance. [Method/process] Based on peer pressure theory, several factors that affect the sharing of humanities and social sciences data are divided into internal pressure and external pressure, and a model of influencing factors for the willingness to share data of humanities and social sciences is constructed, and then empirical analysis is conducted through questionnaire data. [Result/conclusion] The five variables including interpersonal trust, mutual benefit, attitude, group atmosphere, and group system have a positive impact on the researcher’s willingness to share data. Perceived risk has a negative impact on the researcher’s willingness to share. Researchers' willingness to share has a positive impact on sharing behavior.
