This results suggest that environmental dynamism is multi-dimensional, knowledge diffusion velocity affects the knowledge management paradigm and employment strategy, and competitive environment volatility has positive impact on HR flexibility, while its affect on the employment strategy is ambiguous. The results indicate that the enterprises in high knowledge diffusion velocity environment should adopt long-term employment, and the competitive environment volatility affects the methods they manage knowledge employees; when the enterprises face high knowledge diffusion velocity and low competitive environment volatility, they should adopt short-term employment; when those environmental dynamism being both high, the enterprises should adopt multi-employment.
