Abstract：Investigating the differences between China and the United States regarding the impact of technological convergence levels on patent market value holds significant importance for advancing China's strategy of becoming a strong science and technology nation.Based on authorized invention patent data in the field of sustainable development technology in the manufacturing industry from 2005 to 2020 in China and the United States,this study compares the distribution and evolution characteristics of the hierarchy of technological convergence in both countries and their impact on patent market value.The research findings indicate as follows.Chinese patents are primarily concentrated at the CPC main group and subgroup levels of convergence,while U.S.patents are more distributed at the section,class,and subclass levels of convergence,with the differences between the two countries widening over time.Both countries' hotspot technology fields focus on electricity,operations and transport,and mechanical engineering,but China exhibits greater fluctuations while the United States maintains relative stability.Regression analysis shows that higher levels of technological convergence have a more significant positive effect on patent market value enhancement,and this effect is more prominent in China.This study extends technological convergence theory from a spatiotemporal heterogeneity perspective and provides empirical evidence for cultivating high-value patents and formulating differentiated science and technology policies.
