摘要
作为国家能源开发的战略基地,西部地区能源生产系统的产出效益,对国家能源生产安全保障和国家经济持续稳定增长具有重要意义。文章在定量分析西部能源生产系统结构演进状态和产出效益变化的基础上,对能源结构演进与产出效益的相关关系进行综合研究,以期为西部地区调整能源结构和提高能源效率提供一种新的理论视角和实践依据。研究结果表明:能源生产系统的结构演进与产出效益之间存存着显著的相关性,同时也存在着时空不一致性;在系统相对封闭的阶段,产出效益大小取决于能源结构的演进状态,而在系统相对开放的阶段,能源结构的演进状态和自给率变化同时制约着能源生产系统的产出效益。
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 productivesystem. To improvement system construction and promote open-degree is basic premise for increasing output effect of energy production system in west China.
