摘要： 收入差距拉大是当下全球普遍性问题,与此同时全球数字服务快速发展,然而"数字不平等"现象越发严重,数字服务产业已被发达国家主导。在"数字不平等"已成事实的前提下,利用130个国家2007~2019年的面板数据实证分析收入差距对数字服务进口的影响。结果表明,收入差距拉大将显著降低发展中国家数字服务进口,而对发达国家的影响并不显著。在进一步引入工具变量和动态面板数据以缓解内生性问题后,估计结果仍然稳健。研究结果表明除了互联网ICT技术外,发展中国家为赶上数字经济时代和避免被进一步"数字边缘化",缩小收入差距也是其不容忽视且亟待解决的问题。

Abstract: The increasingly wide income disparity is a universal problem in this world. At the same time, the global digital service is developing rapidly, while "digital inequality" is becoming more and more serious, since the digital service industry has been dominated by developed countries. Based on the fact of "digital inequality", this paper makes an empirical analysis about the impact of income disparity on the import of digital service by using the panel data of 130 countries from 2007-2019. The results show that the growing income disparity will significantly reduce the import of digital service in developing countries, which doesn’t have significant impact in developed countries. After further introducing instrumental variable and dynamic panel data to alleviate endogeneity, our results remain robust. By explaining the impact that income disparity has on the import of digital service, this paper suggests that in addition to the development of the Internet and ICT technology, it is also important for the developing countries to narrow the income disparity to catch up with the digital economy era and avoid further "digital marginalization".

Key words: income disparity, digital service import, digital marginalization, instrumental variable, difference GMM
