采用层次分析法和熵权法对全球7个大区和57个国家的油气资源投资环境进行评价和优选,提出投资优选建议,为我国在全球范围内的油气资源投资决策提供科学依据。结果表明,在石油投资环境的排序中,排在前3位的是美国、俄罗斯和挪威;天然气投资环境排在前3位的是美国、俄罗斯和哈萨克斯坦。我国油气资源海外投资优选建议主要体现为以全球能源战略思想为指导,以“重点突破、邻国优先、适当兼顾”为总体发展思路,逐步形成规模大、结构优、竞争力强的能源资源勘探开发与利用体系。
Analytic Hierarchy Process (AHP) and Entropy Method are used to evaluate and optimize the environment for oil and gas resources investment in seven regions and 57 countries. Proposals for investment optimization are put forward to provide a scientific basis for the decision-making of oil and gas resources in the world. The results show that in the ranking of oil investment environment, the top three are the United States, Russia and Norway; the top three natural gas investment environments are the United States, Russia and Kazakhstan. China’s oil and gas resources overseas investment proposals are mainly reflected in the guidance of the global energy strategy, “major breakthroughs, priority of neighboring countries, due diligence ” for the overall development of ideas, and gradually form a large scale, excellent structure, competitive energy Resource exploration, development and utilization system.
