摘　　要：创新驱动发展新质生产力实现共同富裕的新时代背景下,作为“活源之水”的劳动力跨区流动对区域收入差距产生深刻影响,并随技术创新水平而发生“质”的变化。本文以技术创新水平为门槛变量,选取2003—2022年中国省级面板数据为样本,通过构建非线性面板门槛模型实证检验劳动力流动、技术创新水平与区域间收入差距关系。研究发现:劳动力流动对区域收入差距呈现倒“U”型关系。当技术创新水平低于门槛值,劳动力流动显著扩大区域间收入差距;当达到门槛值,劳动力流动对区域间收入差距具有收敛效应,呈现区域异质性;当跨过门槛值,东、北部沿海发达地区的劳动力流出和东北、大西北欠发达地区的劳动力流入驱使区域间收入差距缩小。由此,顺应劳动力流动趋势、消除劳动力流动壁垒、缩小区域间技术创新势差是缩小区域间收入差距,靶向共同富裕的有效路径。In the new era of innovation-driven development of new-quality productivity to achieve common prosperity,the cross-regional mobility of labor as"living water"has a profound impact on regional income gap and experiences a"qualitative"changes with the level of technological innovation.This paper takes the level of technological innovation as the threshold variable,selects China's provincial panel data from 2003-2022 as the sample,and empirically tests the relationship between labor flow,technological innovation level and inter-regional income gap by constructing a nonlinear panel threshold model.It is found that labor flow has an inverted U-shaped relationship to regional income gap.When the technological innovation level is lower than the threshold value,the labor flow significantly expands the inter-regional income gap.When the threshold value is reached,labor flow has a convergence effect on the inter-regional income gap,showing regional heterogeneity.When the threshold is crossed,the outflow of labor from the developed coastal areas in the east and north and the inflow of labor from the less developed areas in the northeast and the Great northwest will narrow the inter-regional income gap.Therefore,conforming to the trend of labor flow,eliminating labor flow barriers,and narrowing the inter-regional technological innovation gap are effective ways to narrow the inter-regional income gap and target common prosperity.
