As a cutting-edge field in the new round of technological revolution and industrial transformation,quantum technology has received great attention.The research on the patent innovation agglomeration of quantum technology industry in China is helpful to support the monitoring of quantum technology innovation situation and provides a basis for the Chinese government to make a good patent strategic layout.The Herfindahl-Hirschman Index(HHI)is introduced to build a patent innovation agglomeration index model,quantum communication,quantum computing,and quantum sensing and measurement are classified as fields,and quantum technology patent innovation agglomerations are calculated and analyzed respectively in technology sub-fields,Chinese provinces and cities,and strategic emerging industries.Further quantitative analysis of patent distribution equilibrium is conducted through the Gini coefficient.The research shows that quantum technology industry innovation of China is developing rapidly,innovative entities are emerging,the trend of decentralized competition in patent innovation in various sub fields is evident,but the degree of regional innovation agglomeration in each sub field is significantly different.The classification of quantum technology patent structures in strategic emerging industries shows diversity,with slightly insufficient innovation in most industries.
