Firm Heterogeneity,Region Heterogeneity and Multi-Factors Mobility
This paper unifies firm heterogeneity,region heterogeneity and multi-factors mobility into the analytical framework of NEG and develops the new NEG model of firm heterogeneity.The results indicate that when a strong condition of industrial agglomeration is met,the enhancement of enterprise distribution heterogeneity strengthens the"black hole condition"of industrial agglomeration;otherwise,it will strengthen the dispersion force of industry;the increase of region heterogeneity makes regional balanced development more difficult.If the initial endowment conditions among regions are the same,symmetric struc-ture may be a stable equilibrium structure,then the symmetric structure stability corre-sponds to the widest range of trade liberalization.Conversely,if the initial endowment con-ditions among regions are different,the interior general asymmetric structure may become a stable equilibrium structure,while the corresponding range of trade liberalization be-comes narrower;under the condition of region heterogeneity,interior asymmetric struc-ture may be a stable equilibrium structure,and the interior asymmetric structure will evolve into a symmetric stable equilibrium structure when the regions are homogeneous.Mean-while,it exists the phenomenon of multiple stable equilibrium structures.With the increase of trade liberalization,agglomeration is possible and gradual,and the process becomes reversible.
