Methodology for delimiting borders of the St. Petersburg agglomeration

Introduction. The lack of unified approaches to (1) formation and development of agglomerations, (2) the regulatory legal framework for the methodological support of agglomeration processes, (3) the official conceptual framework in this area, (4) the assessment of agglomeration effects, (5) the approved methodology for delimiting agglomeration boundaries hinders the process of making informed decisions needed to solve a number of territorial, socio-economic, and transport problems arising in connection with the expansion of trans-regional integratory interactions between various constituent entities of the Russian Federation. In this regard, development of a border delimitation methodology for the St. Petersburg agglomeration is particularly relevant. The subject of the research is regulatory and methodological support for agglomeration processes. The goal is to develop a system of methodological support for creating and developing urban agglomerations within the framework of a well-balanced urban planning policy and legal framework of integratory processes in agglomerations.Materials and methods. The material for the study is the research focused on formation and development of agglomerations. Methods of system analysis and generalization of research results and practical work were applied to set the criteria for delimiting the boundaries of agglomerations. A methodology for delimiting the boundaries of the St. Petersburg agglomeration is proposed on the basis of analysis of research works of Russian scientists, results of practical research by St. Petersburg specialists, and special features of the St. Petersburg agglomeration.Results. The most complex theoretical and methodological problems of delimitation of the boundaries of the St. Petersburg agglomeration are identified; basic principles of formation and development of urban agglomerations are formulated to define the requirements for establishing boundaries; the main criteria for the delimitation of the St. Petersburg agglomeration are formulated, taking into account its specific features. A methodology for establishing the boundaries of the St. Petersburg agglomeration is proposed. Its main stages and research methods, used at each stage, are highlighted. The main problems of the legal support of formation and development of agglomerations are formulated.Conclusions. The research novelty and practical significance of the study result from the problems identified in the field of the regulatory support of agglomeration processes, which do not allow intensifying the development of agglomerations. The proposed methodology for establishing the boundaries of the St. Petersburg agglomeration is based on objective spatial development patterns of the two constituent entities of the Russian Federation and takes into account specific features of their interaction.
