Note(s): This table reports the channel analysis of the relationship between CDT and green bond financing costs. Columns (1) and (2) examine the information transparency channel through environmental information disclosure quality (Envir), while Columns (3) and (4) examine the governance and agency channel through internal control quality (Internal). Industry and year fixed effects are controlled in all regressions. Robust t-values are reported in parentheses. *, **, and *** denote significance at the 10%, 5%, and 1% levels, respectively
