The aim of this paper is to examine whether innovative effort is a key driver of the financial performance of a set of 3860 Spanish companies in a context of financial crisis. For this purpose, we use contrarian case analysis and configural analysis using fuzzy-set qualitative comparative analysis to test the main tenets of complexity theory: (1) innovative effort, as a single antecedent condition, is not a sufficient or necessary factor of a high score in corporate performance; (2) a few possible configurations lead to high corporate performance (equifinality principle); (3) contrarian cases occur; and (4) causal configurations for high scores for corporate performance are not the mirror opposites of causal configurations for low scores for corporate performance (causal asymmetry principle). The findings suggest that innovative effort, as a single antecedent condition, is not a sufficient or necessary factor for a high score in corporate performance.
