3 Trends in global economy Global Economy: shift to urban regions with mass and size? It is a common misperception that megacities have been driving global growth for the past 15 years. In fact, most have not grown faster than their host economies. Today's 23 megacities with populations of 10 million or more will contribute about 10 percent of global growth to In contrast, 577 middleweights cities with populations of between 150,000 and 10 million, are seen contributing more than half of global growth to 2025, gaining share from today's megacities. (Mc Kinsey, 2011)

4 Polycentric urban regions What is the position of polycentric urban regions? 1) How do we organise the economy and the quality of life of polycentric urban regions in a global economy? 2) How to overcome cross border issues? 3) Role of planning?

5 GROW! versus Borrowed Size Strategies

6 GROW!

7 GROW! Why think on a local urban scale? Agglomeration gives a premium on productivity (+5%) Labour markets are localized Subcontracting may be facilitated by proximity (trust) Policy structure / devolution strives for local power Institutions / culture mould economic interaction Competition leads to favoring own strengths Knowledge spillovers are localized to a large extent Consumer City and higher educated Source: Frank van Oort (with Mar_jn Burger, Henri de Groot, Evert Meijers, Mar_jn Smit

8 Borrowed Size Alonso (1973) suggested that economies of scale from polycentrism can be achieved: in certain European urban patterns, such as those of Germany and the Low Countries, whose cities, quite small by our standards, apparently achieve sufficient scale for the functioning of a modern economy by borrowing size from one another (p. 200).

9 Borrowed Size Why think on larger scale? Trade networks are global Structuring corridors are interregional Technological and societal transitions are universal An institutional goal may be integration (e.g. cities, EU) There are common problems and challenges in multiple regions: accessibility, governance, sustainability, growth, demographic change Regions may borrow size or functions from each other (polycentricity) and together also have the 5% premium, given physical, functional and governance relatedness.

10 Borrowed Size Van Oort e.a. The concept of borrowed size can lead to the same positive effects as the concept of agglomeration but... THERE HAS TO BE SOMETHING THAT CAN BE BORROWED, COMPLEMENTED OR COMPETED Source: Frank van Oort (with Mar_jn Burger, Henri de Groot, Evert Meijers, Mar_jn Smit

17 Case Study ABC Region (Van Oort) Conclusions 1. CiFes & urbanizafon are important 2. Borrowed size (func_ons, performance) is important 3. Investments in place- based and in connec_ng network- and governance (coopera_on) structures are needed (in tandem) - for trading, learning, sharing & matching 4. There is a common governance responsibility across all scales and stakeholders of the regional economic ecosystem to make these structures! 5. Coopera_on can do or complement what larger- scale urban governance can do but does it? Source: Frank van Oort (with Mar_jn Burger, Henri de Groot, Evert Meijers, Mar_jn Smit

20 Cross border issues

21 Cross border regions in EU Overview of cross-border cooperation initiatives between small and medium cities in Europe

22 Challenges 1. To combine the means, know-how and resources to acquire a critical mass By pooling resources to set up and operate large scale infrastructure projects or events. By fostering the networking of competencies in order to generate innovation. Research Educa_on Health Environment Economy antoine.decoville@liser.lu frederic.durand@liser.lu

23 Challenges 2. To bring more spatial & functional coherence through the elaboration of common territorial strategies

24 Challenges 3. To provide an international image of the cross-border region Through the promotion of the territory to foreign investors Through the development of a more attractive and welcoming image of the cross-border area antoine.decoville@liser.lu frederic.durand@liser.lu

25 Influencing factors 1. The belonging to a transnational space such as the EU, the Schengen area or the Eurozone and/or the history of cooperation 2. Spatial configurations between small and medium cities In cross-border agglomerations, the authorities are confronted with the necessity to manage together local services and infrastructures. The distance collaboration within polycentric regions is often more flexible and focused on a limited number of strategic collaborations. antoine.decoville@liser.lu frederic.durand@liser.lu

26 Influencing factors 3. The cross-border governance structures Some general principles to improve cross-border governance: To open the governance arena to non-institutional actors To use the available legal instruments and means But the quality of interpersonal relations between policymakers remains crucial to ensure an efficient cooperation!

27 Influencing factors 4. The feeling of sharing a common cross-border living area Events and actions can develop the sense of belonging to a cross-border community of interests. antoine.decoville@liser.lu frederic.durand@liser.lu

28 Ques_ons for the workshop How do you view the chances of GROW! and Borrowed Size? Do these strategies also apply for in between polycentric regions like the Aachen Maastricht Luik / Genk region? Or is there a different, more relevant strategy?

29 Ques_ons for the workshop What is the size (distance / time) of a daily urban system? Connecting the dots : What should be borrowed, complemented? And how to identify these functions? How should be dealt with the cross border issues? What is the role of planning in enhancing polycentric, cross border regions?
