The frictional effect of distance & time-space convergence
- Distance decay or the frictional effect of distance suggests interaction is more likely between nearby areas.
- Due to advancements in transportation and communication, people can now interact over longer distances faster.
- Real-world example: A person in the US can video call someone in Japan almost instantly, overcoming the frictional effect of distance.
Technologies enabling international trade
- Transportation and communication technologies have not caused international trade or TNCs but have allowed them to develop.
- Without these technologies, today's global economy wouldn't exist.
- Real-world example: Amazon, a TNC, uses sophisticated logistics and ICT to deliver goods worldwide.
Transport systems & communication systems
- Transport systems move materials, goods, and people. Communication systems transmit information.
- With the advent of electricity in the 19th century, information could be transmitted faster and further, separating transport and communication as distinct yet related technologies.
- These advancements led to increased mobility and globalized markets, essentially shrinking the world.
Inventions that enhanced economic activity
- Inventions like steam power, railways, and steamships enhanced the scale of economic activity.
- The introduction of commercial jet aircraft, larger ocean-going vessels, and containerization further boosted this process in the mid-late 20th century.
- Jet aircrafts significantly influenced the development of TNCs.
- Real-world example: FedEx, a logistics company, uses a fleet of planes and containerized shipping for global delivery of goods.
Interplay of transport & communication technologies
- Both transport and communication technologies depend on each other for development.
- For example, rail and ocean transport in the 19th century needed the electric telegraph and oceanic cable.
- Similarly, the global transport system now fundamentally depends on telecommunications technology.
Global communication & satellite technology
- Satellite technology has enhanced global communication, especially data transmission, linking computer technologies with information-transmission technologies over vast distances.
- Optical fibre cables have a high carrying capacity, transmitting information very fast and with strong signals.
- Real-world example: Google's cloud services rely on global fibre optic networks for fast data transfer.
