After prolonged rapid growth,China reached the Lewis turning point in 2004.Over the next two decades,China maintained high growth and industrial upgrading,with labor shifting from agriculture to more productive non-agricultural sectors.During this period,the government promoted universal high school and higher education,enhancing the young workforce's educational level.This advancement has driven economic growth and industrial upgrading,leading to a more formal and white-collar employment structure.This paper argues that since 2020,China has completed its economic transition and entered a unitary economy stage.The paper examines labor market changes from several angles:the allocation and pathways of non-agricultural labor,regional human capital convergence,the peak scale of non-agricultural employment,the formalization and white-collarization of the labor market,the central government's development stage assessment and talent dividends,and the age structure of the agricultural labor force.These factors support the conclusion that China has transitioned to a unitary economy,with no surplus labor remaining in agriculture.
