在已有研究基础上,将环境不确定性细分为动态性与敌对性两个维度,分别分析了它们各自对企业创新的影响机理。进一步的,检验了企业集团从属对环境不确定性与企业创新之间关系的调节效应。实证结果表明：环境动态性程度越高,企业更容易加大研发投入；环境敌对性程度越高,企业的研发投入越少。另外,不同类型企业集团的功能不同：从属于产业型集团削弱了环境动态性对研发投入的影响,而从属于控股型集团则削弱了环境敌对性对研发投入的影响。研究结论丰富了组织—环境关系的相关研究,并识别了企业集团缓冲外部环境不确定性的功能,具有一定的理论意义与实践意义。

Based on existing studies, environment uncertainty was divided into two dimensions, named dynamism and hostility, how they influence enterprise innovation respectively was analyzed. In addition, the moderating role of business group in the relationship between environment uncertainty and enterprise innovation was examined. The empirical results suggest that, an enterprise tends to increase its investment in R D when the degree of its environment dynamism is high, and it tends to decrease its investment when the degree of its environment hostility is high. Moreover, the roles of different kinds of business group are different: Industrial business group can weaken the impact of environment dynamism on enterprise innovation, while holding business group can weaken the impact of environment hostility. Our research conclusions are significant in both theory and practice. They enriched studies on the relationship between organization and environment, and identified the buffering role of business group.
