Abstract: Following the award of the 2025 Nobel Prize in Economic Sciences to Philippe  Aghion, a systematic review of his intellectual framework and scholarly contributions has significant academic and practical value. Based on the method of scientometrics, this paper draws a  map of scientific knowledge with the help of CiteSpace and VOSviewer, and combines this with a  study of representative papers and academic monographs to systematically sort out his academic  thoughts and research contributions, and to investigate his academic cooperation, academic influence, and the inheritance and development of Schumpeter's thought. The study found that Professor Aghion took "creative destruction" as the main line and gradually formed an intellectual  framework with the Schumpeterian growth paradigm as the core. He has long explained macroeconomic growth from the perspective of microeconomic mechanisms, incorporated corporate  R&D, innovation incentives, and the replacement of old technologies by new ones into growth  analysis, and attached importance to the impact of market competition and institutional arrangements on innovation activities. Relevant research has gradually expanded to environmental governance, artificial intelligence, and other fields. Professor Aghion's academic research contributions can be summarized in four aspects: theoretical foundation, mechanism deepening, paradigm expansion, and policy extension: ① constructing a Schumpeterian endogenous growth  model; ②revealing the inverted U-shaped relationship between competition and innovation; ③ using the Schumpeterian growth paradigm to explain growth and inequality, the middle-income  trap, secular stagnation, and other real economic problems; ④ proposing the "governmentmarket-civil society" golden triangle governance framework. His cooperation network brings together scholars from different research directions. Continuous communication and cooperation  provide knowledge support for theoretical analysis and empirical research, and also affect the development of his academic thoughts. Relevant papers and monographs have been continuously  cited by scholars in different fields. The citing literature is mainly concentrated in economics  and involves environmental science, political science, and other fields, showing the wide influence of his research results. As an important heir to and developer of Schumpeter's growth  theory, Professor Aghion integrates Schumpeter's ideas on the replacement of the old by the new  and the evolution of innovation into the analytical framework of modern economic growth through  formal modeling, and uses microdata to test relevant theories, so that classical ideas can be used  to explain real economic problems. For China's economy undergoing a deep transformation from  "factor-driven" to "innovation-driven" and then to "innovation-led", these studies provide a  theoretical reference for governing "involutionary competition" and responding to the labor market shocks brought by artificial intelligence. In order to truly release the growth potential of "creative destruction", it is necessary to cultivate a strong innovation ecosystem through in-depth institutional reform, break the monopoly pattern formed by entrenched vested interests, and support this process with a sound social security system and active government guidance, so as to  make creative destruction a sustainable driving force for the high-quality development of  China's economy.
