The book is an expansion of previously published book "Modelling international economic integration and regional economic development: an oscillation theory approach". The book carefully proposes an idea that an inter-disciplinary approach is probably the best and, at least, correct way of treating the dynamics of economic integration. Theories of economic integration and competition, oscillation theory, predator-prey model, telegraph, heat and Navier-Stoxes equations were successfully implemented towards the dynamics of economic integration, trade creation and diversion effects and regional dynamics.
