Abstract: The empowerment of the digital economy to the photovoltaic (PV) industry is not only an inevitable path for the upgrading of the PV industry, but also a core engine for promoting energy transition and achieving the “dual carbon” goals. Qujing, known as China's “Capital of Photovoltaics”, needs to leverage the empowerment of the digital economy to achieve quality improvement, efficiency enhancement, and high-quality development of its PV industry. The digital economy drives quality and efficiency improvement in the PV industry through four dimensions: the reconstruction of factor inputs, the transformation of production methods, the reshaping of industrial chains, and industrial innovation. Driven by the construction of “Digital Qujing”, the digital economy has boosted the production efficiency and benefits of Qujing's PV industry by empowering PV product manufacturing, PV project construction, operation and maintenance management of PV power generation systems, and the extension of the PV industrial chain. E fforts should be made in the following aspects-continuing to enhance the construction of new digital infrastructure in Qujing, accelerating the digitalization process of Qujing's PV industry, advancing the intelligent transformation of the PV industry, and cultivating digital interdisciplinary talents for Qujing's PV industry, to further strengthen the role of the digital economy in empowering the development of Qujing's PV industry.

Key words: digital economy, photovoltaic industry, Qujing, improving quality and efficiency
