Structural Analysis drving Forces Knowledge Based Urban DevelopmentCase study: Tehran Metropolis

Knowledge Based  city or Knowledge Based urban Development (KBUD) is an  new approach and  strategy for  interaction between knowledge and city .this strategy, activate  the knowledge cycle in city  and connect urban economic foundations and driving forces of urban development to By knowledge cycle in urban space, the foundations of economics and the driving force of urban development based economy. This article has been attempted by structural analysis method cluster driving forces of Knowledge Based urban development(KBUD) in Tehran metropolis. This research is  a descriptive-analytic study. theoretical data is provided by on desk and field data with a survey method based on Delphi technique. The statistical population is 20 persons of  urban experts and driving forces including 50 variables in four dimensions of economic, social, environmental and institutional.these variables have been processed by the structural interaction analysis method in MICMAC software. The findings from the overall analysis of the seismic environment showed that 838 has a relation of 3, which means that the relationships of the key driving force are very high and highly influential. The propulsion clustering system indicates the concentration of effective and dual driving force (risk and goal driving force). Of the 50 development driving forces, 15 key drivers include creative class, economic prosperity, effective leadership, research and development, urban diversity and cultural mixing, smart growth, macroeconomic infrastructure, governance and planning, good governance, social justice, effectiveness. The government, the just tax system, environmental sustainability, multinationals and e-government have been identified. Tehran's gradual transition to knowledge-based development requires prioritizing the forces, key drivers, and knowledge-based needs in formulating the city's main development strategy, which must be provided through the foundation of elaborate documents and the context of Tehran's development plan.
