动态环境中战略柔性对企业创新绩效具有重要影响，但对其具体作用机制现有文献还缺乏深入剖析。本文从主动与被动两个角度出发。识别了前瞻型战略柔性与反应型战略柔性，在此基础上引入环境变化速度和环境变化难以预测性为调节变量，提出并验证了两种战略柔性对企业创新绩效的不同作用机制。对长三角制造业企业的实证研究表明，前瞻型与反应型战略柔性均对企业创新绩效有正向影响，但其作用效果和机制存在显著差异：总体来看，前瞻型战略柔性对企业创新绩效的效果更明显；环境变化越迅速，前瞻型战略柔性对企业创新绩效的正向作用越明显；环境变化难以预测性越高，反应型战略柔性对企业创新绩效的正向影响作用越明显。这些结论深化和拓展了战略柔性理论，也为企业的战略实践提供了有益参考。

英文摘要：

Strategic flexibility in a dynamic environment has an important impact on enterprises＇ innovation performance, but an in - depth exploration still lacks in the present literature as to its specific working mechanism. This paper examines the effects of strategic flexibility on innovation performance by incorporating proactive and reactive strategic flexibility into the framework of strategic flexibility, and the moderating effects of environmental change. By conducting an empirical study of 228 sample Chinese manufacturing firms, the results show that ： （ 1 ） Both proactive and reactive strategic flexibility have positive effects on innovation performance; （2） Rate of environmental change positively moderates the relationship between proactive strategic flexibility and innovation performance, and negatively moderates the relationship between reactive strategic flexibility and innovation perform- ance ; （3） Turbulence of environmental change positively moderates the relationship between reactive strategic flexibility and in- novation performance. The results indicate that firms facing fast rate of environmental change should pay more attention to preac- tive strategic flexibility, while facing high turbulence of environmental change should pay more attention to reactive strategic flexi- bility. These results have not only deepened and broadened the theory of strategic flexibility, but also provided helpful references for the strategic practices of enterprises.
