###### Abstract  
The rise of \"cloud-computing, mobile-Internet, Internet of things, big-data, and smart-data\" digital technology has brought a subversive revolution to enterprises and consumers' traditional patterns. Product research and development has become the main battlefield of enterprise competition, facing an environment where challenges and opportunities coexist. Regarding the concepts and methods of product R&D projects, the domestic start was later than the international ones, and many domestic companies have also used successful foreign cases as benchmarks to innovate their management methods in practice. \"Workers must first sharpen their tools if they want to do their jobs well\". This article will start from the relevant concepts of product R&D projects and summarize current R&D management ideas and methods. We combined the bibliometric analysis software Histcite and Citespace to sort out the content of domestic and foreign literature and explore the changing trends of research hotspots. Finally, combined with the analysis of confirmed cases in domestic masters and doctoral dissertations to test the theory, the literature review of the product R&D project management theme was carried out from the dual perspectives of comprehensive theory and practice. This study uses the core collection library of Web of Science as the object of document extraction. Based on the search conditions of \"Product development\" or \"Integrrat\" product development\", 8998 sample documents were initially retrieved. The search deadline was June 2019, with a time range from 2000 to June 2019. Then, using the record number of 50 as the critical condition, 5007 analysis samples were deleted, refined, and cleaned. Through the review and measurement of 5007 papers, the analysis showed that: (1) in the last ten years, sustainability, consumer focus, new approaches to product development management, and organizational design have become critical considerations in the product development process stage; (2) at this stage, researchers are paying more attention to the innovation, design, product development, identification, simultaneous engineering, consequence, and stage/gate model aspects of product development; and (3) factors such as long development cycles, high costs, and poor organizational design are now common problems in the product development process. digital intelligence era; product R&D management; document metrology; informetrics; scientometrics; Web of Science +

market and technological uncertainty, continuous innovation and in-depth research and development have become important ways for companies to build their core competitive advantages. In the 2019 report \"New Economic Species: Practice and Innovation of Chinese Enterprises\", released by the China Development Model Research Center of Cheung Kong Graduate School of Business, it mentioned that in \"the new era of competition, research and development capabilities are the foundation. Technological advancements such as artificial intelligence and the Internet of Things will test the ability of enterprises to experience innovative products\". It can be seen that from R&D to production, sales to service, users to data, and facing the future, companies with collaborative development networks will become development managers of global companies. [PERSON] [1] pointed out that new product development is an essential driving factor for gaining competitive advantage in early research. According to statistics [2], in the mid-1980s, new products only represented about 33% of the company's sales and 22% of the profits. However, in modern enterprises, these two indicators' values have increased significantly, reaching 60% and 50%, respectively. Therefore, today's successful companies are often able to continue to launch high-quality new products. For example, Huawei's number of patent authorizations in 2019 ranked first in China.
