Abstract: Based on Schumpeter’s innovation theory, this paper explored the internal influence mechanism of entrepreneurship on technological innovation diffusion, and discussed the mediating role of knowledge sharing as well as the moderating role of environmental turbulence on the above process. Based on 279 questionnaires, a hierarchical regression analysis was conducted for the empirical test. The results show that entrepreneurship not only directly promotes innovation diffusion, but also indirectly facilitates technological innovation diffusion by enhancing knowledge sharing. Environmental turbulence, i.e., both technological turbulence and market turbulence, negatively moderated the promoting effect of knowledge sharing on innovation diffusion. Moreover, the mediating role of knowledge sharing is significantly different under different circumstances of environmental turbulence, i.e., environmental turbulence has a contingency effect on the mediating effect of knowledge sharing.

Key words: entrepreneurship; innovation diffusion, knowledge sharing, environmental turbulence, moderated mediation effect

摘要： 基于熊彼特创新理论，探讨企业家精神对技术创新扩散的内在影响机制，进一步分析知识共享、环境动荡性对上述作用过程的中介作用和调节作用。基于279份问卷调查数据，采用层次回归分析进行实证检验。结果表明：企业家精神在直接促进技术创新扩散的同时，也通过加强知识共享来间接地促进技术创新扩散；环境动荡性，即技术动荡性与市场动荡性均负向调节知识共享对技术创新扩散的促进作用；环境动荡性较弱的条件下知识共享对企业家精神与技术创新扩散的中介效应显著，反之则知识共享的中介作用不显著。
