Agricultural Factor Structure,Biased-technical Progress And Labor Migration

Structural transformation is one of the most important parts of urbanization process.However,as we know,structural transformation relies on the movement of agricultural labor to non-agricultural sector,whilst agricultural technical change defines the migration speed.Most of the current related studies regard agricultural technique as a single homogenous technique.However,different technology have different functions on agricultural production.Agricultural technical change improves labor productivity,which makes agricultural sector more attractive;while on the opposite side,agricultural technique may substitute labor,which reduces labor demand of agriculture sector.Thus,it is necessary to study the effects of different agricultural technology on labor migration.To this end,we divide agricultural technology into two factor-biased technology.In combined with factor structure,we propose to give an illustration of the question above.Six chapters are included in this paper.Basic background,research significance,innovation and imperfection,related literature and the current situation of China's agricultural labor migration are introduced in the first three chapters.In chapter 4,we present a modified model based on Paula,which use a general equilibrium model to explore the effect of agricultural technique progress on labor migration.Chapter 5 employs China's panel data to guide our empirical works in three steps.Generally,we find that different agricultural technology progresses show heterogeneous effects on labor migration.Specifically,labor-biased technical change would accelerate labor migration.However,we find the opposite effects in the case of land-biased technical progress.Furthermore,we find the acceleration effects of labor-biased technical change are stronger in regions where there are relatively more labor than land,while the absorption effects of land-biased technical change show no difference in the same case.
