激烈的竞争环境推动企业实施开放式创新战略突破组织边界，通过获取丰富的外部知识来弥补自身不足以促进企业成长，但学界对创新开放度、企业成长与知识获取三者之间关系的理论分析和实证研究不足，为此，以国内316家高新技术企业为样本，运用结构方程模型研究验证三者之间的关系。结果表明：创新开放广度与深度对高新技术企业成长的影响具有差异性，不同类型知识获取的中介作用也有所不同。其中，创新开放广度对企业成长没有显著影响，而创新开放深度对企业成长具有正向影响；创新开放广度对显性知识获取没有显著影响、对隐性知识获取具有正向影响，而创新开放深度对显性知识获取与隐性知识获取均有正向影响；显性知识获取对企业成长的影响并不显著，而隐性知识获取在创新开放广度与企业成长之间具有完全中介作用、在创新开放深度对企业成长的正向影响中起部分中介作用。从而得到如下启示：企业要重视开放式创新战略，合理高效利用开放式创新网络；不断提高创新开放深度，有效控制创新开放广度；重视从多种途径获取知识，尤其是隐性知识。

he fiercely competitive environment drives enterprises to implement open innovation strategies to break through organizational boundaries and make up for their inadequacy to promote enterprise growth by acquiring rich external knowledge. However, the theoretical analysis and empirical research on the relationship between innovation openness, enterprise growth and knowledge acquisition are inadequate in academic circles. For this reason, the structural equation model is used to study and verify the relationship among 316 high-tech enterprises in China. The results show that the effects of the breadth and depth of innovation openness on the growth of high-tech enterprises are different, and the mediating role of different types of knowledge acquisition is also different. The breadth of innovation openness has no significant effect on enterprise growth, while the depth of innovation openness has a positive effect on enterprise growth. The breadth of innovation openness has no significant effect on explicit knowledge acquisition and a positive effect on tacit knowledge acquisition, while the depth of innovation openness has a positive effect on both explicit knowledge acquisition and tacit knowledge acquisition. The effect of explicit knowledge acquisition on enterprise growth is not significant, while tacit knowledge acquisition plays a fully mediating role between the breadth of innovation openness and enterprise growth, and a partially mediating role in the positive effect of innovation openness depth on enterprise growth. Thus, we get the following insights: enterprises should attach importance to open innovation strategy and make reasonable and efficient use of open innovation networks. Enterprises should continuously improve the depth of innovation openness and effectively control the breadth of innovation openness. Enterprises should pay attention to acquiring knowledge in various ways, especially tacit knowledge.
