Global supply chains will continue to expand in coming years, but at a slower pace than before, and in ways that follow different patterns, according to a new report from Standard Chartered Bank.

Low-cost manufacturing, for example, is moving westward from coastal cities as wages rise, leading to more goods produced in inland China, India and other Asian nations, the report said. Yet over time, inland wages are likely to increase as well, creating opportunities for other emerging economies.

Increased automation and 3D printing could reduce the advantages of producing goods in developing countries with low labor costs if technology displaces a portion of the workforce.

"World trade growth has been weak recently and the expansion of (global supply chains) has lost momentum," the report's authors wrote. "Some of this slowdown is likely cyclical, but rising wages in China and new automation technologies are challenging the low-wage model, prompting companies to consider re-shoring, or bringing production home."

China's dominant role in the global mass-production and delivery of goods was built largely on low wages and large workforces. But the country's wages rose by eight times between 1995 and 2009. This leaves them well below U.S. wages, but the gap has narrowed, Standard Chartered wrote.

On the whole, wages in emerging markets are still lower, in absolute terms, than in developed countries. Chinese workers, for example, still earn less than $10,000 a year on average, higher only than Mexico, the Philippines and India, according to the bank, which studied about 54 countries. U.S. workers earn about $43,000 a year on average, trailing Japan, Canada, France and Australia.

Average monthly manufacturing wages were about $500 in China, compared with $420 in Malaysia, $360 in Thailand, $240 in the Philippines, $230 and Indonesia, $200 in Vietnam and $140 in Laos, the bank found. More than 20% of companies surveyed by Standard Chartered said they planned to move manufacturing capacity out of China to Vietnam; 15% to Cambodia; 7% to Indonesia and Bangladesh; 3% to Sri Lanka, Thailand and India; and 2% to the Philippines.

The result of these changes are many, but Standard Chartered highlighted a few:

- China is set to become a "megatrader" nation, with stronger ties not just with its neighbors but also countries in Europe, the Middle East and Africa. As China strengthens its communication and IT infrastructure along its trade routes and encourages trading partners to use Chinese currency, the country's role will become more central to global trade, not just a source of cheap labor.

- More providers will relocate to second-tier Asian countries that are emerging as manufacturing hubs, especially those involved in new trade pacts, including the Trans-Pacific Partnership, should they take effect.

- The services sector, rather than the manufacturing sector, will be the biggest generators of supply chain growth in the coming decades, including "manuservices" such as research, design, marketing, distribution, accounting and human resources management. The services sector is becoming more efficient as a result of improvements in technology and communications.
