This study examines the role of public policies in addressing the rapid economic and technological transformations characterizing the contemporary world, particularly in light of the digital revolution, artificial intelligence, and the shift toward a knowledge-based economy. It aims to analyze the extent to which governments are able to adapt to these changes through flexible and proactive policies that promote sustainable economic growth, enhance competitiveness, and maintain social cohesion. The research adopts a descriptive-analytical approach, policy analysis methodology, as well as comparative and foresight methods. It explores the theoretical framework of public policies, analyzes the impact of economic and technological changes on state functions, reviews key international experiences, and highlights the challenges faced by developing countries. Furthermore, the study proposes a policy framework designed to enhance governmental readiness for future transformations. The findings reveal that economic and technological changes have reshaped the role of the state, shifting it from a traditional interventionist role toward that of a regulator, facilitator, and catalyst for innovation. The study also demonstrates that the effectiveness of public policies depends largely on their capacity to integrate technology, invest in human capital, and strengthen institutional and legislative frameworks. Conversely, developing countries face significant structural challenges, including the digital divide, weak education and innovation systems, and limited financial and human resources. The study concludes with a set of recommendations, most notably the need to adopt a comprehensive national digital transformation strategy, strengthen public–private partnerships, and reform education and training systems, in order to transform technological challenges into sustainable development |
