Figure 7.
The scatter plot depicts a Technology Classification Matrix mapping Network Influence on the x-axis against Growth Potential on the y-axis. The x-axis shows Network Influence, Normalized Centrality, from 0 to 1, and the y-axis shows Growth Potential, Forecast Trend, from negative 0.5 to 1. The top right quadrant, labelled High Priority, Core and Growing, includes Signal, Sensor, Control, Device, and Speed with high influence and high growth. The top left quadrant, labelled Emerging, Low Influence and High Growth, contains Manufacturing. The bottom left quadrant, labelled Low Priority, Fading Tech, includes Test and Entrance with low influence and negative growth. The bottom right quadrant, labelled Niche Mature, Core but Stagnant, contains no plotted technologies. Points are colour-coded by category: Active, Hot, and Cold.Technology classification matrix: categorization of core technologies in korea’s railway industry
