Relationship between the comprehensive policy mix I (i.e., at least one policy introduced from each of the four areas) and the comprehensive policy mix II (i.e., all policies introduced that have been included in the CDP questionnaire in a given year) and absolute emissions (specifications 1+2) and emission intensities (specifications 3+4) as the dependent variable with sector, region, and year fixed effects.

The dependent variable includes scope 1 and 2 emissions and is lagged by one year. All specifications only include observations for which all variable data is present. Robust standard errors are computed using the Huber-White heteroskedasticity-consistent estimator.因变量涵盖范围一与范围二排放（scope 1 and 2 emissions），并进行了一期滞后处理。所有计量模型设定仅保留所有变量数据均完备的观测样本。稳健标准误通过Huber-White异方差一致估计量（Huber-White heteroskedasticity-consistent estimator）计算得到。
