High-quality economic development is an economic development concept that emphasizes the transformation of development processes from primarily quantity-oriented expansion toward improvements in efficiency, structural quality, innovation capacity, sustainability, and inclusiveness. Within economics and industrial development studies, it describes a multidimensional development process in which economic growth is accompanied by improvements in resource allocation efficiency, technological progress, industrial upgrading, environmental sustainability, and the coordination between economic performance and social outcomes ^[1]. Unlike conventional economic growth, which mainly focuses on increases in aggregate output or income, high-quality economic development incorporates qualitative dimensions of development, including productivity enhancement, economic structure optimization, and the improvement of development efficiency ^[2]. The concept is analyzed through the interaction of economic growth mechanisms, institutional arrangements, innovation systems, and industrial transformation processes, rather than referring solely to short-term increases in gross domestic product. Within economic development theory, high-quality economic development represents an extension of traditional growth perspectives by integrating quantitative expansion with qualitative improvements in the functioning and sustainability of economic systems ^[3].
