中文摘要:
      研究目标:实证研究工业机器人应用对城镇居民收入差距的影响,并对相关影响机制进行探讨。研究方法:运用双向固定效应模型、工具变量等方法进行因果推断。研究发现:工业机器人的应用显著拉大了城镇居民的收入差距,通过多种稳健性检验和内生性处理后,结论仍然成立。机制分析表明,工业机器人的应用通过对劳动力市场中不同群体就业机会和工资水平的异质性影响进而对整体的收入差距产生作用。此外,分样本回归发现,工业机器人引起的收入差距扩大作用更多地表现在低收入、低教育地区。研究创新:首次利用中国家庭追踪调查和工业机器人使用数据进行研究,并对相关机制进行深入探究。研究价值:从劳动力市场的角度进行分析并为政府决策提供参考。
英文摘要:
      Research Objectives: To empirically study the impact of industrial robot application on the income gap of urban residents, and analyze the relevant impact mechanism. Research Methods: Two way fixed effect model and instrumental variable method are used to estimate the causal effect. Research Findings: The application of robotics has significantly widened the income gap among urban residents. After dealing with endogenous problems through instrumental variable method and multiple robustness tests, the conclusion remains consistent. The further analysis of mechanism shows that the application of robotics has positive effects on the overall income gap through the heterogeneous impacts on the employment opportunities and wage levels of different groups in the labor market. Besides, by the subsample regression, we find that the expansion of income gap caused by robotics application is more significant in low-income and low-education areas. Research Innovations: Using the data of China Family Panel Studies (CFPS) and International Federation of Robotics (IFR), we first studies the effects of robotics application on the income gap of urban residents and explores the relevant influence mechanism. Research Value: From the perspective of labor market, this paper analyzes this topic comprehensively and provide reference for government decision-making.
