Spatial diffusion of innovations


Search this article


The present study investigates innovation diffusion as equivalent to birth-type diffusion. First, the work of Hägerstrand, the substantial initiator in this field, is evaluated in Chapter 2. In Chapter 3, his explanatory framework is validated concerning diffusion phenomena dependent upon the communication process, taking as two examples the 1771 Okagemairi and the Spanish influenza epidemic. In Chapter 4, the examples of electricity supply companies and NHK radio stations reveals that an alternative explanatory framework different from Hägerstrand's should be prepared for diffusion phenomena dependent upon the adoption process. In Chapter 5, a more comprehensive explanatory framework is presented on the basis of the preceding chapers' discussions, which embraces Hägerstrand's explanatory framework and regards entrepreneurial and household innovation diffusion as a chain of events. This explanatory framework, to some extent, follows Brown's, but the author presents as integrated approach further incorporating spatial analysis based on the relational view of space.
