Convergence and depopulation processes in the Center-Periphery system

The paper proposes advancement of a stratum demographic model characterized by the presence two strata — Center and Periphery, which are different in respects their way life, development level social values. processes convergence depopulation heterogeneous system Center-Periphery type were studied. Various variants “catch-up development” Periphery considered within framework numerical simulation. Modes economic growth that contribute to income levels countries indicated, depending on value characteristic time convergence. There identified regimes stable supposedly irreversible Periphery. It is shown participation changing situation might be necessary achieve for maintaining stability entire system. As an explanatory principle observed phenomena, institutional trap concept proposed. A number socio-economic interpretations dynamics as well possibility System behavior control appropriate management decisions discussed results computer modeling. Further proposed may include studying other scenarios interaction taking into account additional migration parameters equations growth.
