Abstract
Migration is one of the main factors that shape and accelerate the development of nations or urban areas, although the dynamics and combined effects of migratory movements, national policies, and the roles of local authorities present a mixed picture in Europe. Some countries have restrictive immigration and integration policies, other nations provide easier access to their political and welfare systems, while the question of local responsibility has also acquired particular importance in recent years. The aim of this study is to explain the linkages between migration policy and development, exploring the variety of European integration policies and their effects on the national socio-economic structures. The integration policy has progressively been becoming ever more important over the last decades. The analysis presents how integration tools interact with national or regional development, emphasizing the role of different migration strategies.
