This paper developed an optimal model of low-carbon urban agglomeration on the base of energy structure under uncertainty. The case study shows that the carbon intensity was decreased by [32.19, 41.20] (%) and energy intensity was reduced by [34.08, 43.19] (%) compared with those in 2010; meanwhile, the carbon intensity and energy intensity in the core area was reduced by [50.88, 54.11] (%) and [51.24, 54.57] (%) respectively, compared with those in 2010. The optimized scheme could not only meet the requirements of 12th Five-Year Planning Outline of Controlling Greenhouse Gas Emission, but also complied with the requirements of regional planning targets. The established model also provided more decision-making space for the sustainable development of low-carbon urban agglomeration.

The financial centre - a cluster? A multiscalar approach and evidence from a case study of Frankfurt/Main: The cluster approach has recently been applied in various studies of financial centres, for example of London or Frankfurt. Its current use in financial geography, however, seems to be more metaphorical than analytical. This paper firstly discusses specific sectoral characteristics which make it difficult to simply apply a concept which was developed for the industrial sector to the financial economy. Secondly, value networks in the production processes of financial products indicate that only certain parts of the production process, i.e. knowledge-based, non-repetitive transactions in the network, require local proximities. Following Gordon/McCann in their reasoning on industrial clusters, it is argued that the cluster approach to financial centres calls for a multi-scalar perspective combining the juridical national territory, the advantages of a large urban agglomeration, and, finally, the network externalities of a district within the urban agglomeration, i.e. the “financial district”. This is demonstrated using the example of the financial centre of Frankfurt/RhineMain, a term which stands for the larger urban agglomeration.
