The existing research on the relationship between innovative knowledge search and open innovation still has the following two gaps. On the one hand, most of the existing researches only focus on the related researches on inbound open innovation, but relatively ignore the generating process and influencing mechanism of outbound open innovation. Due to the differences in innovation forms between inbound open innovation and outbound open innovation, there may be great differences in organizational patterns and innovation routes. On the other hand, although existing studies have discussed its possible influence on open innovation from the perspective of innovative knowledge search and resource bricolage, such independent studies often ignore the role of cross-over connection mechanism. Resource bricolage, as a method of creative use of resources under resource constraints, is not limited to the strength of the enterprise itself, but also emphasizes the process of maintaining the dynamic ability of the organization for the optimization of resource acquisition and utilization. Therefore, from the point of view of the process, resource bricolage is based on the existing resources of the enterprise, re-design the plan, and integrate the internal and external available resources of the organization. Resource bricolage requires the cooperation of the enterprise′s innovation search activities and other organizational actions to seek the best technological innovation strategy.

For the implementation process of open innovation, external innovation knowledge search and resource bricolage are controlled and active activities of monitoring and evaluating new knowledge and resources. Therefore, this study believes that enterprises need to adopt an external-oriented strategic approach to seek more potential valuable knowledge outside the organization; Besides that, in the context of resource constraints, enterprises need to creatively utilize available resources internally, seize market opportunities brought by new resources, and promote two-way open innovation through interactive efforts from both sides. From the interaction perspective of resources bricolage and external innovation knowledge search, this study deem that enterprises needs through the right way to find the best "work" in acquiring knowledge or technology in the technology market, namely to promote enterprise in finding the equilibrium between external knowledge search and internal technology development, to better promote the two-way open innovation in the enterprise. 

By investigating 176 companies from strategic emerging industries in the pearl river delta, this study found: (1) external innovation knowledge search all have a inverted U type influence on two-way open innovation significantly; (2) enterprise resource bricolage activities all impact on two-way open innovation significantly; (3) the interaction of external innovation knowledge search and enterprise resources bricolage impacts on outbound open innovation significant, but its direct impact on inbound open innovation is not significant. The research conclusions of this paper not only enrich the existing theories on the relationship between innovation knowledge search and two-way open innovation, but also discover the interactive effect between innovation search and resource bricolage from the perspective of cross-over effect, and expand the related research on resource bricolage. Our conclusion also provides some management enlightenment for enterprises to implement two-way open innovation strategy.
