This research explores how knowledge spreads in technology fields by looking at both industry types and geographical locations. By studying data over time, the researchers found that knowledge sharing within the same industry is influenced by how close or far apart the locations are. Specifically, sharing ideas across different industries is easier when the locations are nearby, while sharing within the same industry can happen even when the locations are far apart. In the case of France, they discovered that certain types of knowledge benefits more from nearby interactions, which can help industries grow and innovate.
