Research on the effect on enterprise's selection of innovation balance mode in alliance network:from the perspective of network structure

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.
