With the society stepping into the digital economy era from the information age, technological innovation has become the key driving force for the sustainable development of enterprises. Only when enterprises have strong technological innovation capabilities can they gain advantages in rapidly changing market competition and enhance their core competitiveness. This change is especially important for Internet companies, where efficient Internet product R&D management and high-quality and high-volume landing on a large scale have become an important part of the company's core competitiveness.D company is a typical Internet company that actively uses lean digital concepts to scientifically optimize its R&D management system and solves the R&D management problems existing in the company. Therefore, it enhances the core competitive barriers of enterprises in the industry.Firstly, based on the digital economy era as the research background, combined with the actual situation of D company, and according to the development stage of mobile Internet products, this paper explains the importance of products to the company. Then, the paper summarizes the pain points and difficulties encountered in D company's product R&D process, as well as D company's combination with the latest refined digital R&D theory to improve Internet companies' product R&D methods. The research methods include but are not limited to literature research methods, quantitative analysis methods, comparative analysis methods, and case analysis methods.Secondly, the construction goals of D company's lean digital R&D management are set, and lean digital implementation is applied in aspects such as demand classification, communication and collaboration, delivery efficiency, and personnel management and research content according to the needs of Internet product development. And continuously improve and optimize the lean digital R&D system through the PDCA cycle.  Finally, data analysis is performed on the data traces in the R&D process to evaluate the application effect of lean digital driving Internet product R&D. The core focus is on the impact of lean digital technology applications on the economic benefits and social benefits of D company's Internet product R&D. It has not only promoted D company to enhance its core competitiveness in the industry and become a leading Internet product company, but also revealed a model for optimizing Internet product development processes and organizational structures based on lean digital technology.
