Abstract. The purpose of the study was to generate legal support of the socio-economic development model genesis in post-industrial society. Fulfillment the research purpose requires solving several problems. Firstly, to determine the characteristics, components and directions of socio-economic development in post-industrial society. Secondly, to carry out a theoretical analysis of the basic concepts of socio-economic development transformation and to evaluate them. Furthermore, to determine the priority concept of transformation accordingly to the post-industrial development requirements. Thirdly, to develop the main directions of legal support for the formation of a model of socio-economic development of post-industrial society. Several environmental and economic crises, as well as the need to reconstruct the theoretical model of socio-economic development in post-industrial society, made the study relevant. Accordingly, the study intended to identify priority fields of legal support of socio-economic development model genesis. Based on the results of the evaluation of the basic concepts of socio-economic development transformation, the model of socio-economic development in post-industrial society was formed. Accordingly, the main directions of legal support of these processes were developed. The study provides a theoretical analysis of the basic concepts and components of the model of transformation of socio-economic development. An algorithm was developed and the evaluation of these concepts and components was performed, which allowed identifying the most optimal concept and relevant components. Based on this analysis, a socio-economic development model in a post-industrial society has been developed. The directions of legal support of the process of formation of such model were developed.
