ABSTRACT
The production of knowledge takes part in complex networks of firms and individuals. Recent decades have witnessed a period of fundamental change in world-wide economic activities. During this period, the use and supply of information and communication technology (ICT) has broadened and transportation costs have declined steeply, thus further accelerating the process of globalization. However, this process evoked a concentration of knowledge and the knowledge economy in global nodes such as global cities. This chapter provides an insight into the process of knowledge production and how accessibility enables firms to exploit externalities of agglomerations and networks in order to create knowledge. The empirical part of the chapter applies Taylor's world city network approach to analyse global connectivity. This approach provides an empirical instrument for analysing inter-city relations in terms of the organizational structure of knowledge-intensive firms and complements the approach of physical accessibility.
