Ports, railroads, airports, and highways influence economic growth potential as products find their way in and out of the country through the most efficient and cost effective pathways they can. Connectivity in the world-system increases spatial polarization toward global cities in a way their favors economic activities (Friedmann, 1986). Better connections attract more traffic that in turn increases business opportunities.
Cities that have placed themselves strategically, or by good fortune were geographically located in an advantageous locations such as rivers and trade routes, have historically found themselves more wealthy and more cosmopolitan centers of innovation and development. The principles that have applied in the past continue to apply today in a way that influences the wealth and viability of nations.
Supplies and products come in, are converted to higher value goods, and shipped throughout the country. In reverse, raw goods and parts come from the region, are converted into a higher value products and shipped to overseas markets. The business ability of each city will determine what type and how much value they can create.
China found that after they invested in the development of their ports they also realized significant economic growth throughout the region (Song & Geenhuizen, 2014). These infrastructure investments had spill-had effects that reached into various areas of the country. Increased import and export activity opened new opportunities for regional businesses that further justified increased investments.
Think of the world as a round sphere of railroads, highways, shipping lanes, and air traffic routes.
Connecting a city to global networks does take some analysis. Such cities should have a solid manufacturing and technology base to improve and convert incoming and outgoing products. Investments in shipping infrastructure should be based on the needs of the international market and the capacity of the cities current position within existing global supply networks. Likewise, constant development of internal networks is necessary for value building for distribution to markets.
