Regulatory policy in the field of urban planning and development is a key element of public administration aimed at ensuring economic stability, social welfare and sustainable development. In the conditions of globalization and intensive technological progress, effective regulation of urban planning processes is becoming more and more important for solving modern challenges. The purpose of this study is to carry out a theoretical analysis of the concept of regulatory policy in urban planning and development, to study the main approaches to its implementation, as well as to determine modern trends and opportunities for adapting international experience for Ukraine. In particular, the research aims to identify effective models of regulatory policy that can be integrated into national legislation and practice to improve the management of urban development. The research uses a comprehensive approach, which includes the analysis of scientific publications, comparative analysis of regulatory policies of different countries, methods of critical literature review and data synthesis. Special attention is paid to the experience of countries such as the USA, Germany and Singapore, where various approaches to the regulation of urban planning processes are used. The analysis showed that regulatory policy in urban planning and development is a multifaceted phenomenon, which includes such basic approaches as zoning, strategic spatial planning, energy efficiency, integration of transport infrastructure and active involvement of the public in the decision‒ making process. Modern trends in regulatory policy have been identified, including innovative approaches to planning, the use of digital technologies, an emphasis on sustainable development and environmental safety. A comparative analysis of the regulatory policies of the USA, Germany, and Singapore made it possible to identify effective models that can be adapted to the conditions of Ukraine. The study confirmed that an effective regulatory policy is an important prerequisite for sustainable economic development, social stability and protection of citizens' rights. Further research should focus on the integration of digital technologies into regulatory processes, improvement of control and monitoring mechanisms, which will contribute to the sustainable development of cities in Ukraine.
