The Internet Plus initiative has been integrated into many sectors of the economy and society, which profoundly changes the development model, technology, and forms of various fields and constantly enhances the country’s innovation and competitiveness. The new-generation artificial intelligence technology, new information and communication technologies, and new Internet technologies have been integrated with technologies in various fields, driving the digital transformation and upgrades of these fields and ushering in an Intelligence Plus era which is led by intelligence, driven by data, and featured by ubiquitous interconnection, sharing services, cross-field integration, and mass innovation. Against the backdrop of Intelligence Plus, this study summarizes the development status and problems regarding the Internet Plus initiative in China, expounds its new connotations, and demonstrates the architecture and technology system pedigree framework of the Internet Plus system. Moreover, it analyzes the strategic goals and technological routes of the Internet Plus initiative in the Intelligent Plus era in China and proposes specific project suggestions: strengthening fundamental research in order to make breakthroughs in core technologies and focusing on the in-depth integration of the Internet Plus initiative with different fields such as smart manufacturing, modern agriculture, smart energy, people-benefiting services, smart transportation, and smart environmental protection. We also propose that a systematic policy mechanism should be established to support the Internet Plus initiative, laws and regulations as well as standards systems should be improved, and a cross-border integrated talent training system should be created, hoping to provide theoretical references for the development of the Internet Plus initiative in the Intelligence Plus era in China.
