【摘要】 基于专业资本理论，以中国东中西8省（市）667名中小学教师的调查数据为样本，探讨组织支持、知识共享与教师专业资本的关系，发现组织支持显著正向预测教师人力资本、社会资本和决策资本；知识吸收在组织支持与人力资本关系间的中介效应显著，在组织支持与社会资本、决策资本关系间的中介效应不显著；知识贡献在组织支持与决策资本关系间的中介效应显著，在组织支持与人力资本、社会资本关系间的中介效应不显著。学校应通过加强组织支持促进教师知识吸收与知识贡献从而发展教师专业资本，特别是重视搭建促进教师知识贡献的平台促进教师决策资本发展。更多还原

【Abstract】 Based on professional capital theory, this study uses survey data from 667 primary and secondary school teachers across eight provinces(or municipalities) in China to explore the relationship between organizational support, knowledge sharing, and teacher professional capital. The findings reveal that organizational support significantly and positively predicts teachers’ human capital, social capital, and decisional capital. Knowledge absorption has a significant mediating effect on the relationship between organizational support and human capital, but not on the relationships between organizational support and social capital or decisional capital. Knowledge donation has a significant mediating effect on the relationship between organizational support and decisional capital, but not on the relationships between organizational support and human capital or social capital. Schools should enhance organizational support to promote both knowledge absorption and knowledge donation, thereby fostering the development of teacher professional capital, with particular emphasis on building platforms that facilitate knowledge donation to enhance teachers’ decisional capital.更多还原
