Abstract:   The innovative development of the industrial Internet industry faces many challenges in integrating standard innovation and lock-in in key technologies. This paper selected Haier Industrial Internet as the research object and used a vertical single case study method to explore the breakthrough path of technology lock-in in industrial Internet enterprises from the perspective of standard innovation. The research found that the breakthroughs of technology lock-in in industrial internet enterprises is a process of continuously innovating standards to cope with changes in the internal and external environment of the organization. Firstly, based on the dynamic interaction of resource dependence and network embedding levels, the construction of a standard innovation network is achieved, followed by the path logic of "construction of a standard innovation network-improvement of standardization capabilities-breakthroughs in technology lock-in". Specifically, Haier has gone through three stages, in which a learning oriented standard innovation network, an exploratory oriented standard innovation network, and a leading oriented standard innovation network were constructed, which successively formed standard tracking ability, standard participation ability, and standard leadership ability, by means of which breakthroughs were made in low-end technology imitation, key technology reverse engineering, and independent research and development of core technologies. The evolution mechanisms at the transformation stage are the standard participation mechanism and the standard leading mechanism. The research conclusion will provide a new practical path and inspiration for industrial Internet enterprises to make breakthroughs to overcome the dilemma of technology lock-in.
