Micro solution methods solve macro-economic problemNowadays, global financial crisis cause a slowdown in world trade growth. The recent great recession has important impacts on international trade. The international trade has changed from three factors: The evolution of global imbalances, trends in globalization and the structure of trade negotiations.For example, new technologies in manufacturing, connectivity and energy efficiency in particular, have the potential to transform the global economic risk. From macroeconomic perspective these new technologies increase potential growth, allowing the economy to grow faster and it may also put downward pressure on energy price. The US seems as a likely beneficiary, where its competitive advantage in the production and deployment of information technology is widely recognized. Otherwise, some countries' development could be threatened by the substitution of cheaper and more efficient capital for ( labor and by the shortening of global supply chains).I believe new technologies have the potential to solve global macro economic development challenges from micro economic ( every country technological firms cooperation development) method. The reason as below: (1)Recent advances in information and communications technology new innovations in methods of manufacturing and fresh ways of exploiting energy could bring significant growth benefits for the world global economic technological development from different countries themselves technological firms research new ( undiscovered) technological products development to influence future human life, water energy, solar energy, nuclear energy, vehicle battery energy new energy development technology. It aims to avoid global energy shortage challenge occurrence and new artificial intelligent cities development, it aims to let human feel to live in high technological development, artificial intelligent cities can let human to live more comfortable and more convenient in global cities from artificial intelligent assistance.For another example, some of the new technologies allow companies earn higher quality of physical capital at lower prices. Enhanced energy storage, shale gas and oil techniques, and innovations in renewable energy are helping to drive down the price of energy relative to the trend that would have unfolded in their absence. In all cases, new energy development, these technologies have the potential to raise productivity growth sectors and countries, allowing faster, new energy supply growth and lower inflation, when human have different kind of energy to choose to use. For another example, mobile communications technology can make the world economy more efficient and may also lead to significant dislocation. Mobile communications technology has the potential to bring 2 to 3 billion people into the world economy development. Additive manufacturing as 3 D printing, could remove up to 90% of the waste from some manufacturing processes. At the same time, advanced robots which can work as little as USD$4 per hour, may eventually display existing employment in manufacturing. So, on micro economic view point, technology will be one kind production of factor to global future manufacturing firms. Mckinsey Global Institute finds that our trend global growth could be 0.5 to 0.7 percentage points higher in 2025s than in the absence of technological change, it implies productivity gains comparable to apply only personal computer and internet revolutions of the 1990s.However, if these countries' labor can learn how to apply robots knowledge to control robots to help their employer to manufacture products. It is possible that they won't be dismiss, even employers will need them to assist them to control the new robots manufacturing machines to manufacture their products in factories. It depends on whether they choose to attempt to control manufacturing robots or not.
