Functions and modes of information development of economy: methods and models

Informatization intensification of the modern economy stresses the importance to discuss the following group of issues: 1) the establishment of criteria and measurement of the effectiveness of the information system; 2) the definition of the information potential of the agent and the assessment of effective information action; 3) information security of the social and economic system. The purpose of the study is to analyze theoretically the functions of various types of information with the determination of the efficiency of information and the modes of economic systems information development. Economic agents are known to search for relevant information that is only a part of total information in the system to make efficient decisions. The action of an agent as well as the development of an economic system is generally characterised with an efficiency coefficient that assesses the opportunity to obtain relevant information. The research methodology is the classification method that allows us to highlight the properties of information, to introduce quantitative indicators for measuring these properties and using mathematical tools to determine possible relationships between them, building theoretical models of the dynamics of information development of economy. Using this approach the functions of information, namely, notification, accumulation, cumulative amplification within the framework of consideration of the informational interaction schemes “object-agent” and “agent-agent” have been determined. The criterion of information potential of the controlled system and the information efficiency coefficient have been introduced. The latter means the ratio of information security to the level of information completeness of the system. Using the analysis of the dynamics of the efficiency and the ratio of relevant and general information, the modes of information development of the controlled system have been determined; three options for the accumulation of information with the ability to quantify the effect that determines the development of the knowledge economy have been suggested. Standard, enhanced and storage accumulations have been shown in the framework of the “object-agent” information interaction model, formal parameters for their quantitative assessment have been introduced. We have proved that one of the goals of economic policy should be the insurance of the necessary regime of information development of the economy, that is aimed at solving problems in the field of information security due to the fact that the functions of information can be violated, i. e. performed with different results, which indicates the dysfunction of the information system and economic management. Such the approach will reduce the depth of dysfunctions of economic policy measures and the application of the information security loop proposed by the author will provide the tool for comparing the damage and benefits from possible information threats, which predetermines the practical application of the conducted theoretical analysis applied to different information modes. Sustainable development of the modern economy should consider the elimination of information threats especially in the context of overcoming opportunism in the form of deliberate distortions of information in order to obtain additional benefits. At the same time, the use of the information security loop for the development of economic policy measures will allow not only to diagnose the damage and benefits within the existing information processing regime, but also to identify the dynamics of the economic system development as a result of changes in the ratio of information benefits and costs.
