Note(s): This table presents the summary statistics of the sample. Panel A reports the summary statistics of firm characteristics variables. The variables include M&A frequency (Ln_(1 + Count)), return on assets (ROA), market-to-book ratio (MB_Ratio), leverage (Leverage), size (Ln_MV), sales (Ln_Sales), capital expenditures (CAPEX), R&D expenditures (RDX) and cash and short-term investment (Cash). For each variable, we report the number of firms, mean, standard deviation (STD), 25th percentile values, median and 75th percentile values. All variables are winsorized at 1% and 99% to mitigate the impact of outliers. Following Fang et al. (2016) and De Angelis et al. (2017), we also compare the differences of various firm characteristics between the pilot and the control group in 2003, the year immediately before the start of the pilot program and report the t-statistics of the difference. Panel B reports the classification of M&A deals year by year. The sample period is from January 2001 to December 2010, excluding 2004. See appendix for a detailed description of the variables
