Abstract: In this paper, the measurement indicators of enterprise high-value patents are constructed by taking the listed manufacturing companies from 2014 to 2018 as is research object and through the adoption of the panel data from China Stock Market Accounting Research (CSMAR) Database, National Public Service Platform for Standards Information and CNKI- Chinese Standard Full-text Database (SCSF). Meanwhile, the influence mechanism of high-value patents on enterprises' technical standardization capabilities is discussed, and the relationship between high-value patents and technical standardization capabilities in enterprises of different sizes is also further analyzed through the application of resource-based view and signal theory and the integration of patents, standards and resource factors in enterprise context into the same research framework. It is revealed in the research that: (1) High-value patents are conducive to improving enterprises' technical standardization capabilities; (2) Enterprise scale has a positive regulatory effect on the relationship between high-value patents and enterprises' technical standardization capabilities. That is to say, compared with small-scale enterprises, high-value patents of large-scale enterprises play a greater role in promoting enterprises' technical standardization capabilities.
