A geographical concentration of businesses enables them to mitigate the drawbacks arising from their small size. It is therefore important to highlight the existence of such zones and their location in regions where most businesses are SMEs, such as the Valencia Community region. Moreover, it is particularly important for technological companies, since such concentrations act as a means of increasing their productivity. By using georeferencing software, SatScan, four zones with a high concentration of technological companies are identified superimposed on zones with a very industrial tradition. The profile of the companies analysed could be of interest in implementing suitable industrial policies.
