China Import and Export Emergy Analysis

Import and export from China’s environmental and economic systems are analyzed to study current resources utilization by emergy anaysis. Domistic resource, purchased energy, materials input and outputs in environment and human society were identified. The emergy contrastive analysis between import and export from 1985 to 2005 reveals that the majority of resource depletion has been brought about by China’s internal booming development, China’s economy has benefited from recent international trade, and China makes great contributions to the world economy. However, increasing resource depletion impels China into exploiting indigenous resources and depending increasingly on international resource markets. The amount of waste generated as the main byproduct of resource depletion grows continuously every year, so domestic increasingly rigorous ecological and environmental problems is unavoidable.
