Analysis of Structural Effect of Energy System in West China
西部能源生产系统结构演进效率分析

Energy resource has been resulting in the most enormous effect than other kinds of resources during the long-term mankind development fulfillment. The development speed of the nation and region more and more depend on the supply ability of energy productive-system. China, on the other hand, as the biggest developing country, had propped up great achievement in second half of 20 century which is inseparable with powerful energy supply. On the other hand, as the most increasing quickly nation of world energy consumes, its energy problem has caused the international social concern. The situation of both side becomes the rigorous challenge to the limited energy productive-system in China. As a strategic mothball base for energy development of nation, the output effect of energy production system in west China influences national security of energy production and sustainable development of the whole country. Based on analysis of structural evolution and output effect, the paper synthetically studies relativity about structural evolution and output effect of energy production system in west China, thus laying a instructive reference for further energy exploitation in west China. The results show that evident relativity exists between structural evolution and output effect of energy production system. Output effect is decided by structural evolution on condition of relatively closed energy production system, and structural evolution and open level both make a decisive impact on output effect of energy productive-system. To improvement system construction and promote open -degree is basic premise for increasing output effect of energy production system in west China.
