“…In addition, external knowledge acquired by proactive boundary-spanning search enhances firms' ability to cultivate external awareness (Barasa et al, 2018) and predict latent emergencies in advance (Hillmann, 2021), thus building precursor resilience. However, excessive proactive boundary-spanning search will lead to knowledge redundancy, and it will be difficult for firms to identify the most valuable information from redundant knowledge (Ferreras-Méndez et al, 2016), which will narrow firms' attention (Hoppmann et al, 2021) and then hamper firms' ability to predict and handle potential emergencies. Moreover, too little proactive boundary-spanning search cannot enable firms to accurately identify and predict the trend of environmental changes, which further makes it difficult for firms to take proactive actions for unexpected events, and then impede precursor resilience.…”
