Political ideology not only influences political activities, but also apolitical fields such as charitable giving. However, empirical studies regarding political ideology and charitable giving have yielded mixed results. To find out the effect size and explain the variation in effect sizes, we deploy a meta-analysis to estimate the average effect size and examine the potential moderators from four perspectives. Following scientific data collection and coding procedures, we identify 421 effect sizes from 31 empirical studies. Our meta-analysis results suggest that political conservatives are significantly more charitable than liberals at an overall level, but the relationship between political ideology and charitable giving varies under different scenarios. Furthermore, meta-regression results indicate that the measure of charitable giving, the type of charitable giving, and controlling for religiosity can account for the variation in effect sizes.

政治意识形态不仅影响政治活动，还影响慈善捐赠等非政治领域。然而，关于政治意识形态和慈善捐赠的实证研究产生了好坏参半的结果。为了找出效应量并解释效应量的变化，我们部署了一项荟萃分析来估计平均效应量并从四个角度检查潜在的调节剂。按照科学数据收集和编码程序，我们从 31 项实证研究中确定了 421 个效应量。我们的荟萃分析结果表明，在整体层面上，政治保守派的慈善程度明显高于自由派，但政治意识形态与慈善捐赠之间的关系在不同情景下有所不同。此外，元回归结果表明，慈善捐赠的衡量标准，
