Using manufacturing firm-level data in 25 transition economies, this paper examines the impact of China’s exports on training of firms in importing countries. We find that imports from China increase the training probability and the training ratio of production and non-production workers. After using instrumental variables to solve endogeneity problems, the results are robust. When the industry is more human capital intensive, the impact is greater. In order to cope with import competition from China, firms need to improve the skill level of employees when encouraging innovation and adoption of new technology, and firms increase the training for employees. On-the-job training is an important source of human capital, this paper provides new evidence for the positive effect of China’s export.
