Energy Diversification Pathway Of China For Energy Security

The rapid increase in energy consumption has brought issues such as energy supply and demand imbalance, which makes energy security has become an international subject of widespread concern. Environmental pollution and climate change caused by energy use also seriously threat the sustainable economic development. As the world's fast-growing economies, China's energy demand particularly strong. While, China accounted for nearly three-quarters of global energy consumption growth in 2008. How to ensure energy security has also become China's a great challenge.As an important strategy for energy security, the theoretical significance and practical value of energy diversification have gradually caught scholars and policy-makers' attention. Diversification of energy resources reduces the over-reliance on a single or few energy options through the provision of multiple choices. Since it can reduce the risk of supply disruptions on one hand, and ensure that energy use does not cause irreversible impacts on the environment on the other hand, Energy Diversification is an important means to ensure energy security from the system level.This paper first analyzed the research background and theoretical relevance of this subject, and straightened out the existing research home and abroad, summed up the research trends and weaknesses. Then, based on defining energy diversification and energy security, used the energy economic theory to systematically analyze the relationship between energy diversification and energy security, then from the point of view of portfolio theory, analyzed diversification the scope of the role of energy security. Next, build the energy security-oriented MDA model of China's energy diversification, using time-series data on energy consumption to dynamic analysis China's diversity and energy security performance of the. Then, analyzed the multiple trades-offs during diversification path selection process. Based on establishment of system performance optimization models in different contexts, establish the optimal combination selection mechanism of China's energy diversification from the system level. Try to explore a diversification path selection method with a combination of resources and socio-economic conditions. Finally, in summing up the study of this paper, gave some policy recommendations for China's energy diversification.
