Innovation activities of private firms are crucial for sustainable economic growth in every society. Therefore, the majority of firms around the world spend large amounts of capital (money, time, and human resources) in searching for novel innovative opportunities in the marketplace. In our study, we sought to understand how the openness of firms' external search strategies (external search breadth and external search depth) affects firms' innovation capabilities as measured by awareness, decision-making, interpretation, and implementation capability. Furthermore, using survey data collected from 112 Chinese manufacturing firms over a six-month period, this study conducted an empirical analysis about the association between firms' innovation capabilities on the type of innovation (exploratory innovation vs. exploitative innovation). This study also provides important managerial insights for manufacturing companies.
