Abstract: Enterprises need to balance the exploration innovation and exploitation innovation to ensure both current and future viability, thus it is urgent to select a proper balance mode of innovation. Based on fitness landscape theory and complex network theory, this paper builds balance modes about ambidexterity and punctuated equilibrium based on the NK model, and examines how the network structure effects the selection of the balance mode. The results show that, (i)when the network structure is conductive to access to external knowledge, the enterprise selecting ambidexterity can improve the innovation performance; when the network structure is not conductive to access to external knowledge, the enterprise selecting punctuated equilibrium will get a high short-term performance, and ambidexterity will lead a high long-term performance; (ii)the innovation complexity or environment dynamics does not influence the selection of the balance mode, but the ambidexterity will have more advantages when the innovation complexity or environment dynamics increases.

摘要： 企业通过平衡探索性创新和利用性创新来保证短期和长期的发展，如何选择适合的创新平衡模式成为亟需解决的重要问题。基于适度景观理论和复杂网络理论，在NK模型的基础上对企业的双元和间断两种创新平衡模式建模，通过仿真模拟考察联盟网络结构如何影响企业创新平衡模式的选择。结果表明：（1）当网络结构有利于企业获取知识时，企业选择双元模式有利于提升创新绩效；当网络结构不利于企业获取外部知识时，企业选择间断模式能够获得较高的短期绩效，选择双元模式能够获得较高的长期绩效。（2）创新复杂程度和环境的变化不会影响企业在网络中创新平衡模式的选择，但随着创新复杂程度或环境变化程度的增加，双元模式越来越有优势。
