Abstract: Based on the theory of innovation ecosystem, this paper constructs a moderated mediation model by introducing innovative ecological environment and innovation niche. Based on the survey data of manufacturing enterprises in the Yangtze River Delta, it explores the impact of innovation ecological strategy on corporate innovation efficiency through innovative ecological network by using the bootstrapping method. The results show that the innovation ecological strategy has a positive impact on the corporate innovation efficiency. The innovation ecological network plays a mediating role in the relationship between the innovation ecological strategy and the corporate innovation efficiency. In addition, the innovative ecological environment and the innovation niche moderate the mediation relationship. The research results further enrich the theoretical research of innovation ecosystem by constructing an intermediate transformation mechanism from innovation ecological strategy to corporate innovation efficiency from the perspective of innovative ecological network.

Key words: innovation ecological strategy, innovative ecological network, innovation niche, innovative ecological environment

摘要： 基于创新生态系统理论，通过引入创新生态环境和创新生态位，构建一个有调节的中介效应模型，并基于长三角制造业企业调研数据，采用Bootstrap方法进行检验，探究创新生态战略通过创新生态网络对企业创新效率的作用机理。研究结果表明：创新生态战略对企业创新效率具有正向影响；创新生态网络在创新生态战略与企业创新效率关系中发挥中介作用；并且创新生态环境和创新生态位调节该中介效应。研究结果从创新生态网络视角构建了创新生态战略向企业创新效率转化的中间机制，丰富了创新生态系统理论研究。
