Based on the data of A-share listed companies from 2006 to 2016, the influence of slack resources with different liquidity levels on organizational resilience was studied. The findings are as follows: first, unabsorbed slack resources have an effect from promoting to inhibiting on organizational resilience (inverted U-shaped), while absorbed slack resources have an effect from inhibiting to promoting on organizational resilience (U-shaped). Furthermore, the panel threshold regression method is used to explore the threshold characteristics and quantitative relationship between slack resources and organizational resilience. By taking the firm size as the threshold variable, it is found that the threshold effect of absorbed slack resources is significant, which reflects that absorbed slack resources play a different role in different firm sizes. Secondly, based on the situational characteristics of organizational resilience, it is found that slack resources have heterogeneity in different periods of severe adversity events and among enterprises of different ownership.
