In the context of open innovation, enterprises’ thirst for innovation resources is increasing day by day. Faced with limited resources, innovation search behavior, as a way to collect and learn information such as knowledge and technology to increase the novelty of resources, is an important way for enterprises to break through the status quo in order to obtain a wider range of resources and improve the innovation of enterprises. However, in the existing literature, there are many studies on the impact of innovation search behavior on innovation performance, but the existing studies are scarce and paradoxical regarding the influencing factors of antecedent variables of innovation. In today’s rapidly evolving society with faster product iterations and changing consumer needs, the market competition environment is becoming increasingly fierce, which leads to higher standards for enterprises to carry out innovation activities. More and more enterprise managers find that by relying on their own resources, they cannot adapt to the changing market environment and cannot obtain sustainable innovation advantages. Enterprises need to actively conduct innovative search behaviors to obtain resources according to their own state, and innovative resources need not only include internal resources but also external resources, which are open. In this context, the open innovation behavior of enterprises is promoted through innovation search behavior, and sustainable competitive advantages are obtained to ensure the sustainable development of enterprises.
