An economic corridor is an infrastructure that helps facilitate economic activities. Figure 6.1 shows the stages involved in the development of an economic corridor. A corridor can be national (for example, Leipzig-Frankfurt corridor, Tokyo-Osaka corridor), regional (for example, GMS or CAREC corridors), or even international (for example, submarine telecommunication cables or energy pipelines). Trade facilitation and logistics services are the main catalysts in the development of economic corridor. Economic corridor helps strengthen industrial (or, services) agglomeration over time through establishment of industrial zones (or, SEZs) and facilitates clustertype development of enterprises.
