Industrial software integration is the foundation to support the production and digital transformation of industrial enterprises. It is also the core for realizing product lifecycle management. Identification resolution path is key to realizing the interoperability of all industrial elements and thus conducive to the deep integration of industrial software. In view of the data and business islands faced by industrial software integration in China, we analyze the demand for industrial software integration from perspectives of product design and production, quality information traceability, and production–financial integration. Subsequently, we examine the development history of industrial software integration in China and abroad and summarize the challenges from the aspect of data interoperability and full-set software procurement. Additionally, we propose a development idea of combining industrial software integration with identification resolution, focusing on physical gateway, interface platform, and cloud component technology; the idea includes the technical architecture, identification resolution technology path, data management mode, and core functions. Finally, we suggest to promote the coupling of the identification resolution system with industrial software from the aspect of development of industry drive, corporate culture, and talent support.
