摘　　要：文本使用熵权法求得地级市数字经济发展指数,运用中国276个地级市2011-2019年的面板数据,以城乡居民收入差距为切入点,研究数字经济发展对共同富裕的影响。研究发现:数字经济发展对城乡居民收入差距的影响呈现先缩小后扩大的U型特征,即数字经济发展对共同富裕产生先促进后抑制的效果;从拐点值看,东部地区最大、中部地区次之、西部地区最小;与高行政等级城市相比,这种U型特征在低行政等级城市更为明显。同时,“宽带中国”示范城市政策对城镇居民的增收效果优于农村居民,拉大了城乡居民收入差距。未来,既要鼓励数字技术创新催生助农新模式,发挥数字经济的共同富裕效应,又要加强数字农民培育弥合城乡“数字鸿沟”,防范数字经济发展抑制共同富裕的风险。This paper first uses the entropy weight method to obtain the digital economy development index of prefecture-level cities,and then uses the panel data of 276 prefecture-level cities in China from 2011 to 2019,focusing on the income gap between urban and rural residents,to study the impact of digital economic development on common prosperity. The paper finds that the impact of the development of the digital economy on the income gap between urban and rural residents presents a “U-shaped” characteristic of narrowing first and then expanding, that is,the development of the digital economy will first promote and then inhibit common prosperity. As regards the inflection point value,the eastern region is the largest,the central region is the second,and the western region is the smallest. Compared with cities of higher administrative level,this “U-shaped” feature is more obvious in cities of lower administrative level. At the same time, this paper also finds that the “Broadband China” demonstration urban policy has a better effect on increasing the income of urban residents than rural residents,thus widening the income gap between urban and rural residents. In the future,we need to encourage digital technology innovation to create new models of supporting agriculture and bring into play the common prosperity effect of the digital economy. We should also strengthen the cultivation of digital farmers to bridge the digital divide between urban and rural areas,and guard against the risk that the development of the digital economy may inhibit common prosperity.
