Abstract: The quantum industry is the focus of current scientific and technological innovation, and it is also the breakthrough to lead a new round of scientific and technological revolution and industrial transformation. As an emerging industry, the quantum industry is in the initial stage of industrial development, and its innovation process will inevitably encounter problems such as "market failure",which requires policy guidance and support. This paper uses the content analysis method and social network analysis method to identify the distribution characteristics of quantum industry policies, and analyze its current situation and problems based on the three-dimensional analysis framework of policy tools, policy objects and policy strength. The results show that the use of policy tools in China's quantum industry policy system is diverse but lacks balance, the policies covers a wide range of objects but lack of coordination, and the average policy strength grows steadily but the overall strength is weak. Therefore, this paper puts forward to increase the number of demand-side policy tools, optimize the structure of supply-side and environment-side policy tools, strengthen policy pertinence and coordination, and improve the legislative construction of quantum industry in order to advance the high quality development of China's quantum industry.
