Using the method of analysis and synthesis, this paper carries out the evaluation of the interaction of oil companies and financial capacity of the Russian Federation on the structural elements of the national financial system as a methodological framework for the interdependence assessment. With the use of logical framework analysis we have revealed the resource orientation of the Russian economy and substitutional character of the factor of oil prices influence on the financial capacity of the state. We have also studied the positive and negative effects of dependence of state financial capacity on the financial capacity of oil companies. Based on an assessment of the current state of mutual influence of oil and gas companies on the formation of the financial potential of Russia, we have indicated and reasoned the direct and indirect impact which creates the induced effect of interference by increasing or decreasing the financial capacity of the state in view of its potential structure-forming components. In order to evaluate the interaction of financial capacity of oil companies and the state, as a methodological framework for the assessment of interference we have proposed a mechanism of system interaction of directly proportional positive and negative connections of structural elements of the enterprise and the state financial potential. This approach creates a platform for improving methodological approaches to the assessment of the potential interaction of financial business entities and state which could be implemented within corporate management and the mechanism of state fiscal policy.
