The rise in inequality in most countries over the past two decades is one of the biggest challenges facing economic policymakers in both developed and developing countries. Several economists see technological progress as a key factor in income inequality. Therefore, this paper attempts to study the impact of technology on income inequality through meta-analysis. This paper collected 14 articles that met specific criteria and obtained 222 estimators from them. Then, it classified and coded the measurement of technology and inequality, data sources, model setting and control variables of different research to study the overall mean effect of technology on income inequality and the heterogeneity among different studies. Firstly, it is found that technological progress significantly increases income inequality after considering the heterogeneity of different studies, and there is an obvious positive publication bias. Secondly, Skill-biased Technical has the greatest positive impact on income inequality. Thirdly, using wage gape of skilled workers as a measure of income inequality yields even greater results. Lastly, the newer the data set used, the smaller the impact of technology on income inequality reflected by the data set.
