Definitions and forms of interaction of legal entities in the aspect of constitutional economics

The article investigates the problem of interaction of subjects of economic relations in the aspect of constitutional economics, which is relevant for both legal science and practice.It is noted that in scientific doctrine there are different interpretations of the term interaction. Various scientists emphasize the specificities of an interaction as a certain process andprovide their own definitions of interaction. Given that the subject of this study is constitutional economics, the author’s definition is proposed.It is important to highlight, that if an economic relationshipinvolves a group of subjects endowed with state functions, on the one hand,and private entities, on the other,then their interaction is designed to satisfy both public and private interests. The participants are in a horizontal relationship with each other, not in a relationship of power and subordination. The interaction of governmental and non-governmental actors is aimed at achieving a clearly defined goal, including the establishment or change of legal regulation of certain economic relations, achieving certain economic results, implementing economic reforms, solving socio-economic problems, etc.  Taking the Ukrainian legal reality into consideration, it is proposed to analyse some forms of interaction within the domestic economy, which are actively used in our country. Thus, it is noted that a common form of interaction between government and business is the creation of advisory bodies and working groups, which include both representatives of public authorities, civil society and business.It is noted that lobbying is a common form of public-private cooperation in the world, but there is no legislation on lobbying in Ukraine, and bills registered in parliament are characterised by significant shortcomings.One of the most successful models of interaction between government and business is public-private partnership, which helps to achieve synergies and implement large-scale projects in various sectors of the economy, including social, from road construction to space exploration.The social responsibility of entrepreneurs is also mentioned as a form of constructive interaction between government and business.
