语言距离与民族地区县域劳动力流入——基于数字普惠金融的新证据

Dialectical Distance and the Inflow of Labor in Ethnic Regions——The New Evidences Based on Digital Inclusive Finance

在实现共同富裕的目标导向下,推动劳动力流入民族地区县域是实现区域协调发展、促进民族地区高质量发展的重要举措。作为民族文化的载体,语言是影响劳动力流入民族地区县域的重要因素,而数字普惠金融引致的包容性增长给劳动力流入带来新契机。论文以是否愿意长期定居作为意愿型流入、以住房属性作为实质型流入,研究发现,语言距离显著降低了劳动力流入民族地区县域的概率。以地形起伏作为语言距离为工具变量进行内生性检验和更替变量进行稳健性检验均佐证了此结论。机制检验发现,语言距离通过阻碍劳动力在民族地区县域的社会融入降低了其流入可能性。而数字普惠金融显著增强了社会融入与劳动力流入的正向关系。基于数字普惠金融服务程度发现,数字普惠金融覆盖面和数字化程度对社会融入与劳动力流入民族地区县域发挥正向调节作用,但数字普惠金融服务深度调节作用不显著;基于数字普惠金融服务方式分析发现,数字信贷和数字支付发挥正向调节作用,但数字投资的调节作用不显著。

Guided by the goal of achieving common prosperity,promoting the flow of labor into ethnic areas and counties is an important measure to achieve regional coordinated development and high-quality development of ethnic areas.As the carrier of ethnic culture,dialect is an important factor affecting the inflow of labor into counties in ethnic areas,and the inclusive growth caused by digital inclusive finance brings new opportunities for labor inflow.In this paper,the willingness to settle down for a long time is regarded as the willing inflow,and the housing attribute is the substantive inflow.The study finds that the dialect distance significantly reduces the probability of the labor force flowing into the counties in ethnic areas.Endogenous test with topographic relief as dialect distance as instrumental variable and robustness test with replacement variable both support this conclusion.The mechanism test finds that dialect distance reduces the possibility of labor inflow by hindering the social integration of labor in ethnic counties.Digital financial inclusion significantly enhances the positive relationship between social integration and labor inflow.Based on the degree of digital inclusive financial services,it is found that the coverage and digitization of digital inclusive financial services have a positive moderating effect on social integration and labor inflow in ethnic counties,but the deep moderating effect of digital inclusive financial services is not significant;based on digital inclusive financial services The method found that digital credit and digital payment play a positive regulating role,but digital investment regulating role is not significant.
