Answer:
industry economies of scale
Step-by-step explanation:
industry economies of scale refers to a situation when the production of a certain industry become more efficient compared to early years of formation.
This situation can be achieved when we concentrated a specific type of industry within the same region (for example, Hollywood is where the film industry is concentrated , silicon valley is where the software industry is allocated , etc)
When an industry is focused on one place like this, every other components that support the industry (such as professional labors in programming field, actress and raw materials to make movies) will most likely flock into this area. This will eliminate various costs that derived from time, distance, and other causes of inefficiencies.
