This article aims to measure the technological gap of the Internet of Things (IoT) in the new technological revolution and propose policy recommendations for optimizing innovation routes. To this end, this paper establishes a technology gap test model through the indices of paper activity power, paper influence, patent activity power, patent influence, and patent market power, at the same time, the Gordon method is used to standardize scoring, in order to clarify the fine-grained technology gap between China, the United States, Europe, Japan, and South Korea in the field of the Internet of Things. Through comparative research, it has been found that China's IoT technology innovation is in a paralleling competitive stage with Europe, America, Japan, and South Korea, but there are issues such as weak international competitiveness. Therefore, policy recommendations for optimizing innovative routes are proposed for problem research, in order to provide support for relevant research and policy decisions.
