Abstract: Abstract：Based on the framework of theory of planned behavior, through the theoretical deduction and the empirical studies of 545 questionnaires, this paper reveals the generating mechanism of scientific and technological personnel innovative behavior in China situation. First, the study gives the definition of scientific and technological personnel innovation behavior attitude, subjective norm, perception behavior control, and then subdivide them as endogenous and exogenous attitude, mandatory norm and demonstration norm, self-efficacy and control ability respectively, testing the affections they have on the behavior of innovation through the mediating role of innovation intend；Second, explores the direct influence of the key variable to innovation behavior；Finally, tests the regulatory role of the organizational support in the conversion process of innovation intend to innovation behavior. The empirical results show that the endogenous attitude of behavior attitude have a positive effect on the innovation behavior through the complete mediating role of innovation intend, the demonstration standard of subjective standard and the two dimensions of perception behavior control (self-efficacy and control ability) have a positive effect on innovation behavior through part mediating role of the innovation intend；the exogenous attitude of behavior attitude and the mandatory norm of subjective norm have no effect on innovation intend, but can directly affect innovation behavior positively；Organization support has a positive regulatory role in the relationship of innovation intend to innovation behavior, this function mainly reflects in the superior tool support.

摘要： 摘要：本文以计划行为理论为框架，通过理论推演与545份问卷的实证研究，整合个体内部因素、环境因素、工作特征等诸多创新行为影响因素，揭示了我国情境下科技人员创新行为产生机理。首先，本研究对科技人员创新行为态度、主观规范、知觉行为控制的内涵进行界定，进而将其分别细分为内生态度与外生态度、指令性规范与示范性规范、自我效能和控制力，验证了它们通过创新意愿的中介作用对创新行为的影响；其次，探索了上述关键变量对创新行为的直接影响作用；最后，检验了在创新意愿向创新行为转化过程中组织支持的调节作用。实证研究结果显示：行为态度的内生态度通过创新意愿的完全中介作用对创新行为产生正向作用，主观规范的示范性规范与知觉行为控制的两个维度（自我效能和控制力）通过创新意愿的部分中介作用对创新行为产生正向作用；行为态度的外生态度和主观规范的指令性规范对创新意愿没有影响，但可以直接正向影响创新行为；组织支持在创新意愿对创新行为的影响关系中起正向调节作用，该作用主要体现在上级工具性支持上。
