在分析跨部门知识分享特性的基础上,基于行为战略的理论逻辑,构建角色承诺、跨部门知识分享和企业技术创新绩效的理论模型并提出研究假设。研究发现,角色承诺对跨部门知识分享、企业技术创新绩效均起着倒U型的影响,跨部门知识分享对企业技术创新绩效提升起着正向影响,跨部门知识分享在角色承诺和企业技术创新绩效间起中介作用。

英文摘要：

Drawing on behavior strategy theory,this study aims to examine the relationship among role commitment,cross-sector knowledge sharing and technological innovation performance.Results of an experience-sampling study of 239 firms show that there exists＂inverted U＂relationship between role commitment and cross-sector knowledge sharing,and cross-sector knowledge sharing has a direct positive effect on firm technological innovation performance.There exists＂inverted U＂relationship between role commitment and firm technological innovation performance either,and crosssector knowledge sharing plays a intermediary role between role commitment and firm technological innovation performance.
