This provides ample scope for imprecise application and occasional misuse of the term. Polycentricity t
6、ends to be opposed to hierarchic systems of cities. It has to be acknowledged that the meaning of polycentricity is wholly context-dependent that is, it depends on countries territorial and demographic characteristics, their urban development patterns, their institutional organization and so forth.
7、In its wider scope, polycentricity can refer to the multiple spatial clustering of almost any human activity at any scale. 2. A working definition might be that polycentrism as the opposite of monocentrism is a spatial development model based on networks of cities that seeks the enhancement of terri
8、torial cohesion and addresses territorial disparities by rethinking the allocation of development and productive resources. It aims to reduce the negative effects of spatial over-concentration at any scale while tackling core-periphery disparities. It envisages integrated economic development inclus

In the real world, unbalanced urban systems and uneven urban and rural development are common. Land flight and urbanization have persisted, albeit at different times and paces and

Suburbanization and dispersal have become widespread, often increasing the economic and social polarization of urba

Migrants from less developed regions seeking work in cities may have difficulty adapting to urban lifestyles. Their precarious and sometimes illegal settlements have often compounded urb

More recent rebalancing strategies have tried to create viable conditions in the countryside to retain its inhabitants or, conversely, to alleviate urban congestion and the plight of urb

Arguably, on the urban scale, any multi-functional, spatially differentiated agglomeration is polycentric. A recent version of intra-urban polycentrism is Eb

Contemporary urban renaissance advocating mixed development in compact cities is the latest versi

On the regional scale, the self-contained, poly-functional “new towns” conceived to ease congestion in British and later French cities, or de Gaulles “mtropoles dquilibre” in France, could be seen as a deliberate effort of postSecond World War regional polycentrism. Conversely, monofunctional housing areas stemming from private speculative suburban railway and road development in parts of Europe and North America could be construed as dysfunctional polycentricity. Societies have developed intra-urban and regional polycentric models througho
