In recent years, the Chinese financial industry has significantly enhanced its support for the real economy's quality and efficiency. However, there are still numerous constraints hindering the high-quality development of finance. The concept of new quality productive forces can theoretically guide the practical development of financial innovation. Existing literature on the concept and connotations of new quality productive forces in the financial sector, as well as its impact on the high-quality development of finance, is just beginning. Particularly lacking are definitive definitions and interpretations of financial new quality productive forces, as well as profound theoretical research promoting high-quality development of finance. This article first explores the essence of financial new quality productive forces, emphasizing it as the fundamental driving force behind high-quality financial development. It plays a leading role in technological and pattern innovation, combining financial technology innovation with industry innovation in a way that conforms to the laws of financial development as an advanced productivity state. Secondly, based on the Perez technology-economic paradigm, it argues that financial new quality productive forces not only possess basic characteristics of high technology, efficiency, and quality, but also feature technological-economic characteristics such as data-driven processes, technological innovation, cross-border integration, and open collaboration. Building upon these characteristics, the article further constructs a theoretical analytical framework encompassing three dimensions: "momentum, format, and ecology", to clarify the theoretical logic of how financial new quality productive forces promote high-quality financial development. Moreover, it analyzes the constraints faced by financial new quality productive forces, including issues such as inadequate financial infrastructure adaptation, insufficient control over financial technology innovation, untapped potential in high-quality financial data elements. and the inability of financial innovation to meet the demands of real economy financial services. Finally, from academic exploration and perspectives on financial innovation, the article proposes relevant suggestions to effectively implement financial new quality productive forces and empower high-quality financial development. In contrast to previous literature, this study expands in two main aspects: firstly, it comprehensively discusses the definition and essence of financial new quality productive forces, summarizes its technological-economic characteristics of data-driven, technological innovation, cross-border integration, and open collaboration, which lays a theoretical foundation for its role in promoting high-quality financial development. Secondly, it systematically analyzes the inherent mechanisms through which financial new quality productive forces promote high-quality financial development, exploring potential operational mechanisms. This research partly reveals the internal logic through which financial new quality productive forces promote high- quality financial development, aiding in constructing a distinctive Chinese modern financial system and an open, innovative financial ecosystem, steadfastly advancing along the path of China's unique financial development.
