  1. This table presents the pooled OLS estimation results for linear relationships between the firm innovation and CPQS Impact (CPQSIM) and Amihud's (2002) illiquidity ratio (ILLIQ). The dependent variable is INNOV_EXP and INNOV_PAT respectively. The definition of all variables is provided in Appendix A. For brevity, year and industry dummies are suppressed and only double-clustered adjustments are reported in parentheses. N is the number of firm-year observations. ***, ** and * denote statistical significance at the 1%, 5% and 10% levels, respectively
