Abstract: This paper examines the impact of industrial robot application on urbanrural income gap in the context of the advent of the intelligent manufacturing era and Chinas sustained lead in the installation and stock of industrial robots worldwide Utilizing panel data from 271 cities across China，the study reveals significant insights into the relationship between industrial automation and urbanrural inequality
Our findings are summarized as follows First，the application of industrial robots significantly narrows the urbanrural income gap A one standard deviation increase in the density of industrial robot installations can lead to an average reduction of 33% in the urbanrural income gap over the sample period Second，industrial robots enhance the income of rural migrant workers，thereby reducing income disparity However，there is also an effect that widens the gap by increasing the disparity in urbanrural fixed asset investment per capita and total profits，but the overall net effect is to reduce the urbanrural income gap Third，heterogeneity analysis shows that the application of robots in cities with more developed agriculture has a smaller effect on reducing urbanrural income gap In cities with a higher concentration of hightech industries，the application of robots leads to increased income for both urban and rural residents Furthermore，the application of robots allows highskilled migrant workers to earn more but remit less back to rural areas 
The marginal contributions are as follows Firstly，the study explores the impact of industrial robot application on urbanrural income gap against the backdrop of Chinas industrial robot boom and the urbanrural divide，providing crucial evidence that technological progress may positively contribute to common prosperity Secondly，the study explains the micromechanism of how industrial robot application affects urbanrural income disparity，offering microlevel evidence for macrooutcomes Thirdly，the studys mechanism indicates that the impact of industrial robot application on urbanrural income gap is bidirectional，with both “expanding” and “narrowing” effects，but the net effect is the latter This finding aids in enhancing the “narrowing effect” of industrial robot application on urbanrural income gap and suppressing the “expanding effect”， thereby better serving the common prosperity of urban and rural areas

摘要： 在智能制造时代来临、中国工业机器人安装流量和存量持续保持世界第一的背景下，本文基于全国271个城市的面板数据，探讨了工业机器人应用对城乡收入差距的影响及其内在机理。研究发现，工业机器人的应用显著缩小了城乡收入差距，这一结论在经过一系列内生性检验和稳健性检验后依然成立。机制分析发现，工业机器人的应用提升了农村转移人口收入，进而减少了城乡收入差距。此外，工业机器人的应用也存在通过扩大城乡人均固定资产投资差距和增加利润总额从而扩大城乡收入差距的效应，但总体净效应仍然表现为缩小城乡收入差距。同时，在农业更发达的城市，机器人的应用对城乡收入差距的缩小效应更小；在拥有更多高技术行业的城市，机器人的应用可以使城镇居民和农村居民都获得更多收入；机器人的应用使农村转移人口中的高技能劳动力能够获得更多收入但更少寄回农村。本文的研究为政府如何同时引导产业升级和实现共同富裕提供了一定的参考。
