Innovations in construction as a factor of technological renewal, increasing competitiveness and sustainable development of the industry

The aim of the article. In modern conditions of rapid economic development, intensive urbanization and digitalization, the construction industry is one of the leading sectors of the national economy, which determines the quality and comfort of the spatial environment. At the same time, global challenges, increased competition, growing requirements for environmental safety and production efficiency necessitate the active implementation of innovative technologies and management approaches in construction. Innovations are a key factor in technological renewal of the industry, increasing its competitiveness and ensuring sustainable development in conditions of high capital intensity, long-term life cycle of objects and complexity of coordination between participants in the investment and construction process. Analysis results. The article analyzes the essence, structure and classification of innovations in the construction industry, as well as their impact on the efficiency of construction enterprises. Innovation activity is considered as a purposeful process of creating, distributing and using new or improved technologies, materials, management methods that increase the quality, efficiency, safety and environmental friendliness of construction products and processes. The complex and interdisciplinary nature of innovations, covering technical, organizational, economic and digital components, is emphasized. The main components of the innovation structure in construction are determined: scientific and technical, technological, organizational, economic, legal and social components. The life cycle of innovation is characterized, which includes the formation of an idea, assessment of potential, research phase, design, production implementation, operation and diffusion of innovations. The innovative environment of the construction industry is analyzed, which includes research institutions, construction enterprises, design organizations, investors, state regulators and innovation clusters. It is shown that the effectiveness of innovation implementation depends on the coordination between these participants and the level of readiness for cooperation. A classification of innovations is proposed by the nature of novelty (radical, improving, combined), level of impact (technological, organizational, informational, environmental, social), place in the construction process, source of initiation, level of management, duration of implementation and origin. Such systematization allows for more clearly planning the innovation policy of enterprises, predicting efficiency and managing the innovation portfolio. Conclusions and directions for further research. It is emphasized that innovations contribute to increasing labor productivity, reducing costs, improving the quality and reliability of construction work, reducing project implementation times, increasing environmental sustainability and optimizing management. They are not only a tool for technical improvement, but also a factor in the strategic competitiveness of construction companies. Therefore, ensuring sustainable innovative development of the construction industry requires not only technical renewal, but also the transformation of management approaches, institutional architecture and corporate culture. The success of innovation depends on the openness of enterprises to change, readiness for risks, the formation of partner networks and integration into innovation ecosystems.
