Weber said that four forces affect both cost of distance and spatial development patterns: (1) Changes in information and communication technology that facilitate speedy and inexpensive transfer of ideas across space; (2) innovations in production technology and productivity-enhancing investments that are embedded in the innovations and concentrate production spatially; (3) transportation investments that speed transfer of people and products and movement of innovation across space; and (4) agglomeration economics that favor concentration of people and production across urban space.
