摘要
不同于新古典劳动经济学和制度主义对农民工频繁换工的讨论,本文从信息经济学视角对数字技术影响农民工“短工化”现象进行了考察。对2019年中国社会状况综合调查数据进行实证发现,数字技术对农民工“短工化”具有显著正向影响,即数字技术助推农民工“短工化”现象,在加入主要控制变量、地区虚拟变量后,结论仍然成立。为克服实证模型潜在的内生性问题和选择性偏误,运用工具变量条件混合估计法、倾向得分匹配法和多种稳健性检验后,所得结果依然支持数字技术对农民工“短工化”行为的正向效应。进一步异质性分析发现,数字技术对男性、“新生代”“低学历”和本地农民工“短工化”行为的助推作用更大。研究结论不仅为数字技术影响农民工工作转换提供事实依据,而且为引导数字技术助推农民工稳就业提供政策启示。
Unlike discussions on the frequent change of migrant workers from the perspectives of the neoclassical labour economics and institutionalism,this paper,based on the data of the 2019 China Integrated Social Survey,finds that digital technology has a significant positive impact on migrant workers'shortage of work.To overcome the potential endogeneity and selectivity bias of the empirical model,the results of this paper still support the positive effect of digital technology on the shortening of migrant workers'labour force after applying the conditional mixed estimation of instrumental variables,the propensity score matching method and various robustness tests.Further heterogeneity analysis reveals that digital technology contributes more to the‘new generation’,‘low⁃skilled’and local migrant workers‘short⁃timing’behaviour.The findings of this study not only provide a factual basis for the impact of digital technology on migrant workers'job transitions,but also provide policy implications for guiding digital technology to promote stable employment of migrant workers.
