The subject of the study is the impact of sustainable development technologies on the formation of strategic management and the improvement of the efficiency of development companies in a dynamic market environment. The focus of the work is on the integration of environmental, social, and economic principles into the corporate governance system, as well as the development of methods for assessing the impact of sustainable technologies on the performance of development projects. The subject encompasses the analysis of transformational processes resulting from the implementation of energy–efficient, innovative, and socially oriented technologies that ensure the competitiveness of companies in the global market. Particular attention is given to the development of management models that combine long–term economic goals with environmental balance and social responsibility. Thus, the subject is a systematic study of how sustainable development technologies influence the strategic flexibility, resilience, and operational efficiency of development companies, shaping new standards of corporate governance.The purpose of the article is to substantiate the role of sustainable development technologies as a key factor in enhancing the strategic efficiency of development companies in a dynamic market environment. The study identifies the main directions for integrating environmentally oriented innovations into the strategic management system of enterprises. The purpose is also to establish scientific and methodological foundations for assessing the impact of sustainable technologies on the economic, social, and environmental performance indicators of companies. The practical aspect of the work lies in developing recommendations for improving management decisions focused on sustainable development, enhancing efficiency, and ensuring the long–term competitiveness of development enterprises.Research Methodology. The methodological basis of the study consists of systemic, analytical, and interdisciplinary approaches that make it possible to comprehensively assess the impact of sustainable development technologies on the strategic aspects of managing development companies. Methods of comparative analysis are used to compare traditional and sustainable management practices, and economic–mathematical methods are applied for the quantitative assessment of the efficiency of implementing energy–efficient and environmentally friendly technologies. Correlation–regression analysis is employed to identify dependencies between technological innovations and the financial performance of companies. The SWOT analysis method is used to determine the strengths and weaknesses of technological transformation, while the PESTEL analysis assesses the influence of external factors of sustainable development. Scenario modeling and system dynamics methods are also applied to forecast the effects of implementing sustainable development technologies under market volatility. Business Intelligence (BI) and GIS modeling tools are used to visualize results and develop analytical conclusions. The methodological framework ensures a multidimensional study that combines economic analysis, environmental assessment, and strategic planning.Research Results. As a result of the study, it was determined that the implementation of sustainable development technologies has a multiplicative effect on the strategic efficiency of development companies. Economic efficiency is manifested through the reduction of operational costs due to the introduction of energy–saving systems and renewable energy sources, which simultaneously increases profitability and investment attractiveness. Environmental efficiency is achieved through the reduction of CO2 emissions, the utilization of construction waste, and the use of environmentally friendly materials. The social component is expressed in improving living conditions, creating an inclusive environment, and increasing public trust in development projects. A model of strategic integration of sustainable technologies is proposed, which includes four management levels: resource, operational, social, and institutional. The results confirm that companies implementing sustainable development principles demonstrate higher stability in crisis conditions and an increased ability to adapt within a dynamic market environment.Conclusions. The conducted research proves that sustainable development technologies act as a catalyst for the strategic transformation of development companies. They change not only the approach to resource management but also the conceptual logic of strategic planning, where the key priorities are environmental balance, social responsibility, and long–term economic stability. The implementation of energy–efficient technologies, digital monitoring systems, eco–friendly materials, and «green» innovations enhances corporate performance, reduces risks, and improves market reputation. From a strategic management perspective, sustainable development is not only a contemporary necessity but also a tool for achieving competitive advantages. Development companies that actively adopt environmentally oriented solutions become examples of combining efficiency and responsibility, forming the foundation for the sustainable growth of the industry. Thus, sustainable development technologies should be viewed not as an additional function but as a key component of corporate strategy that determines the future resilience and performance of development enterprises.
