The current study estimates the impact of manufacturing servitization on industrial productivity from the perspective of global value chain division. For this purpose, from 2000 to 2014, the study uses the World Input–Output Database (WIOD) to measure the servitization level of China’s manufacturing industry based on the non-competitive input–output model. Moreover, it develops a unified framework of source and structural differences in service factors and explores the mechanism and impact of manufacturing servitization on industrial productivity from the perspective of global value chain division. The results showed that if the division status of the manufacturing industry in the global value chain is higher, there will be a higher productivity effect of servitization. Regarding service factor country difference, foreign service factor input positively strengthened the industrial productivity effect, whereas domestic service factor input had no obvious effect on industry productivity. Furthermore, it was found that distribution and transportation services do not play a significant role in promoting industry productivity, whereas modern service factors such as information technology, finance, and business services have significant driving effects on industry productivity. The study suggests optimizing the layout of the industrial chain and improving the servitization of the manufacturing industry.
