Drawing on the Broaden and Build theory, this study investigates how and when receiving gratitude shapes public servants' service innovative behavior. Based on a multi-wave, multi-source survey study of 398 public servants and their paired leaders in Chinese civil service sub-district offices, the results empirically support expectations that receiving gratitude during public service can promote public servants' service innovative behavior. Specifically, receiving gratitude during public service promotes public servants' positive emotions of meaningfulness, further promoting service innovative behavior. Moreover, high emotional intelligence strengthens such processes. Theoretical and practical implications are also discussed.

Keywords: Public servants; emotional intelligence; meaningfulness; quantitative research; receiving gratitude; service innovative behavior; the broaden and build theory.

本文基于“扩展与构建理论”，研究了收到感激如何以及在何种情况下会影响公务员的服务创新行为。通过对398名中国基层政府机关的公务员及其配对领导进行多阶段、多来源调查，结果实证支持了这样的预期：在公共服务中收到感激可以促进公务员的服务创新行为。具体而言，在公共服务中收到感激会增强公务员有意义感的积极情绪，从而进一步促进服务创新行为。此外，高情感智力加强了这种过程。本文还讨论了理论和实践意义。
