As the society pays more attention to environmental issues and the development of a green,low-carbon economic system,manufacturing firms begin to regard green technological innovation as an effective strategy to obtain sustainable competitive advantage.However,existing research has paid little attention to the relationship between boundary-spanning search and green technological in-novation.Therefore,it is worth clarifying the role of boundary-spanning search on green technological innovation.Drawing on knowledge-based theory and resource orchestration theory,this study explored the influence of boundary-spanning search on green technological innovation,and examined the mediating role of organizational resilience and the modera-ting role of knowledge orchestration capability.To test the theoretical model,we selected manufacturing firms as research object.The results indicated that:(1)Reactive boundary-spanning search and proactive boundary-spanning search have significant positive influence on green technological innovation.(2)Reactive boundary-spanning search positively affects organizational in-ternal resilience,while proactive boundary-spanning search positively affects organizational external resilience.(3)Organiza-tional internal resilience partially mediates the relationship between reactive boundary-spanning search and green technological innovation,and organizational external resilience partially mediates the relationship between proactive boundary-spanning search and green technological innovation.(3)Knowledge orchestration capability plays a significant moderating role between boundary-spanning search and organizational resilience,and moderates the mediated effect of organizational external resilience between proactive boundary-spanning search and green technological innovation.This study has made several theoretical contributions.First,this study uncovers the effects of two boundary-spanning search on green technological innovation,and enriches the research on antecedents of green technological innovation.Second,the result finds that boundary-spanning search impacts organizational resilience,and reveals the differential impacts of two types of boundary-spanning search on organizational resilience.Third,this study uncovers the partial mediating role of organizational re-silience,and enriches the antecedents of organizational resilience.Fourth,this study finds the moderating role of knowledge orchestra-tion capability,and clarifies the effect of knowledge orchestration capability on green technological innovation.This study also has some management implications.First,firms should develop a scientific plan for boundary-spanning search,and strengthen the establishment of formal and informal external cooperation networks.Second,firms should establish crisis awareness and cultivate a long-term vision,pay attention to searching for knowledge ahead of competitors,and carry out diversified cooperation.Third,firms should enhance internal members'interaction,reconfigure existing green resources and technological capabilities,and attach importance to green intelligent manufacturing.
