不同类型创新生态系统如何推动核心技术开发与企业销售增长——以中国电子信息技术产业为例

高科技产业技术创新复杂度急剧提升，营造创新生态系统已成为企业保持长期竞争优势的一种重要战略选择。基于知识管理、技术依存结构与网络外部性等视角，利用中国电子信息技术产业上市公司2007-2017年面板数据，探讨相关技术多元化与非相关技术多元化创新生态系统推动核心技术开发、企业销售增长的深层次机理。结果发现：营造相关技术多元化创新生态系统有助于企业打造核心竞争优势，促进核心技术开发，并借此实现企业销售增长;营造非相关技术多元化创新生态系统不仅能够直接促进核心技术开发与企业销售增长，更有助于丰富互补配套产品技术体系，激发间接网络效应，与相关技术多元化创新生态系统形成耦合效应，从而共同促进企业销售增长。

How do Different Types of Innovation Ecosystem drive core Technology Development and Enterprise Sales Growth

The complexity of technological innovation in high-tech industries has increased dramatically, and creating an innovative ecosystem has become an important strategic choice for enterprises to maintain long-term competitive advantage. Based on the perspectives of knowledge management, structure of technological interdependence and network externalities, using panel data of China's electronic information technology industry listed companies from 2007 to 2017, this paper explores the deep-seated mechanism of creating different types of innovation ecosystems to promote the core technology development and enterprise sales growth. The results show that creating a "related technological diversification innovation ecosystem" can help enterprises to create core competitive advantages, promote the development of core technologies, and achieve sales growth of enterprises; creating a "unrelated technological diversification innovation ecosystem", which not only directly promotes the core technology development and enterprise sales growth, enriching complementary product technology systems, inspiring indirect network externalities, and coupling with "related technological diversification innovation ecosystem" to promote enterprise sales growth.
