Study On Decision Optimization Of Cooperate Objective Selection Of China's Oil Companies In International Exploration And Development

Objectives selection decision on international oil cooperation is a key step for the development strategy of internationalization for domestic oil companies, which is influenced by oil reserve, economic power, politic situation, regulation base, infrastructre, contract mode, and so on. By now, the resource-based powers are applying very harsh oil contract modes and associated financial taxation items to severely control the profits for foreign oil companies, which brings a huge risk on the international cooperation profits and oversea business development of China's oil companies, and a new challenge for objectives selection decision optimization of international oil cooperation on both theory and methodology.This dissertation was guided by the combination of business strategic management theory, decision optimization theory, oil geo-political and economic theory, and investment environment evaluation theory, studied on the objectives selection decision optimization of international oil cooperation for domestic oil companies by phases and multiple targets, enriched the potential evaluation indexes on international oil cooperation, improved profit evaluation methods on international oil cooperation projects, perfected the decision optimization theory on objectives selection of international oil cooperation, and acquired some original research achievements as follows:(1) Designed and perfected potential evaluation index system on international oil cooperation. The dissertation combined the contract mode with the resource base and investment environment initially to construct the index system. With the perspective of domestic oil company, this dissertation enhanced the evaluation pertinence, and enriched the indexes measure-methods, so as to realize the overall evaluation on cooperation potentials between domestic oil companies and international oil resource countries.(2) Constructed an effect function on international oil cooperation, on the levels of contract profit, net cash flow, and effect influence factors. Based on the systematical analysis on international oil contract mode and taxation items, and the comprehensive comparison of effect evaluation methods on international oil cooperation projects, the dissertation analyzed the effect influence factors and adjustment factors with the guidance of cash flow, and constructed the effect function on international oil cooperation respectively in accordance with specific contract modes.(3) Constructed a decision optimization model on international oil cooperation objectives selection, with the combination of multiobjective programming in project cluster decision and matrix model in risk decision. On the basis of resource potential evaluation of resource-based powers, and effect evaluation on oil contract modes, the dissertation constructed the decision optimization model on international oil cooperation objectives selection for domestic oil companies in accordance with the dual objectives for China's oil companies of guaranteeing national oil resource supply and pursuing business economic profits, to provide a tool for the objective selection decision of China's oil companies. The model set the overall profits of international cooperation of domestic oil companies as objective function, and the oversea investment amount and the supply diversity of oversea oil productivity as the constraint conditions.(4) Accomplished the application study on decision optimization on objectives selection of international oil cooperation. The dissertation, based on cooperation potential evaluation index system, made comprehensive evaluation and gave an ordering on major oil resource-based powers with the methods of factor analysis; took some major oil resource-based powers in A area as objectives to perform the application study on the model constructed, and put forward some cooperation suggestions and strategies, which provides a new thought for our oil companies to make objectives selection decision on international oil cooperation.
