The existing economic evaluation index system of oil-gas exploration project lacks environmental efficiency index and social efficiency index, and has no definite risk index. This paper analyzed the existing economic efficiency indexes, added the social efficiency and environmental efficiency indexes. These indexes can efficiently reflect the project’s difference, moreover, the data can be obtained easily. This paper designed the indexes, which can weight project geology risk, the project risk and the economic risk. These indexes composed a systematic and comprehensive system of oil-gas exploration project economic evaluation index. This index system can reflect the project characteristic from different angles, and provide the policy-making reference for the policy-maker.

Projection Pursuit Model

To realize the coordinated and sustainable development of hydropower projects and regional society, comprehensively evaluating hydropower projects’ influence is critical. Usually, hydropower project development has an impact on environmental geology and social and regional cultural development. Based on comprehensive consideration of complicated geological conditions, fragile ecological environment, resettlement of reservoir area, and other factors of future hydropower development in each country, we have constructed a comprehensive evaluation index system of hydropower projects, including 4 first-level indicators of social economy, environment, safety, and fairness, which contain 26 second-level indicators. To solve the problem that existing models cannot evaluate dynamic nonlinear optimization, a projection pursuit model is constructed by using rough set reduction theory to simplify the index. Then, an accelerated genetic algorithm based on real number coding is used to solve the model and empirical study is carried out with the Y hydropower station as a sample. The evaluation results show that the evaluation index system and assessment model constructed in our paper effectively reduce the subjectivity of index weight. Applying our model to the social impact assessment (SIA) of related international hydropower projects can not only comprehensively analyze the social impact of hydropower projects but also identify important social influencing factors and effectively analyze the social impact level of each dimension. Furthermore, SIA assessment can be conducive to project decision-making, avoiding social risks and social stability.

Regional energy efficiency evaluation stands for the analysis of regional energy efficiency whose aim is to figure out the low– and high– efficient parts in energy consumption, providing most economic suggestions to improve energy efficiency. Based on the energy balance sheet, this paper decomposed the energy efficiency of one entire region into different sub-regional values and then got the energy efficiency index of each sub-region through standardized treatment. Further, the overall energy efficiency index was calculated out through weighting to lay the foundation of energy efficiency analysis and energy saving potential evaluation. Besides, this paper analyzed and compared the 2010 and 2006 energy efficiency data of China (including 30 provincial-level administrative regions) with a result that the evaluation index system of regional energy efficiency could satisfy the energy saving and managing demands, like location and analysis of regional energy efficiency level .

The Index System

Effectiveness evaluations are one of the important ways to guide grid investment and to improve investment efficiency. Improving the effectiveness of grid investment evaluations is studied based on the optimization of the investment evaluation index system and the utility evaluation model. The index system is optimized by establishing an evaluation index system of grid investment effectiveness, considering the redundancy between the indices, and constructing an ISM-DEA model. The utility function model was introduced to fully consider the different risk appetites of decision-makers, and a utility evaluation model that takes risk appetite into account was established. An improved weight integration model based on multiobjective optimization was established by considering the minimum deviation and the trend-optimal objective function when setting the index weights. The calculation results show that the feasibility of the index system optimization model and utility evaluation model constructed in this study is verified under the premise of satisfying the assumptions. By adjusting the risk preference coefficient of decision-makers, the dynamic optimization of the grid investment utility evaluation results can be realized.
