An Evaluation of the Petroleum Investment Environment in African Oil-Producing Countries Based on Combination Weighting and Uncertainty Measure Theory

Recognizing that the evaluation of overseas petroleum investment environment is affected by many uncertain factors and there are problems with current methods, this paper proposes a mathematical model an oil resources environment, based on combination weighting uncertainty measure theory. Combining international theory characteristics industry, establishes index system for linear function each index. Using subjective weight obtained using analytic hierarchy process together objective entropy method, optimal was minimum relative information entropy. A multi-index matrix top 12 oil-producing countries in Africa calculated. Finally, credible degree recognition criterion used to judge order level environment. This provides effective method The results show Nigeria Angola have best climate, followed Algeria, Egypt, Libya. In general, important strategic partner China rich resources. Although Africa’s industry fraught complex challenges headwinds, also present opportunities.
