With the rapid development of information technology, the industrial boundary is gradually blurred, and industrial cross-border integration brings new impetus for innovation development and value co-creation. High-tech industrial parks are characterized by industrial diversification, but few studies have analyzed how industrial integration in high-tech parks enhances the value creation of the entire high-tech park from a value perspective. In this study, we build a value network model of the Beijing Economic-Technological Development Area (BDA) based on grounded theory research methods to explore the mechanism of value co-creation among industrial chains in the BDA. Additionally, we found that the communication network infrastructure represented by 5G, the Internet of Things, and the Industrial Internet, the new technology infrastructure represented by artificial intelligence and blockchain, and the computing infrastructure represented by the data center in BDA are integrated with the leading industries, which improves the value of the industry and promotes the digitalization, networking, and intelligent transformation and upgrading of the industry. Contributions for future research are presented.
