Industrial Policy and Domestic Value‐Added in Production and Exports: The Chinese Experience
The World Economy, Volume 48, Issue 7, Page 1630-1653, July 2025.ABSTRACT This paper studies the role of China's industrial policy in the evolving share of domestic value added (DVA) in its production and exports. We propose a method to quantify the DVA share in exports by extending. With national input–output tables and trade statistics from 2007 to 2020, we see a strong increase of the DVA share in exports and a ...

Critical Factors Governing the Frictional Coefficient in Mg Alloys—Learn From Machine Learning
Engineering Reports, Volume 7, Issue 5, May 2025.Machine learning models were successfully used to predict the friction coefficient of Mg alloys based on composition, processing, mechanical properties, and tribological parameters. Normal load, elastic modulus, and Zn content are the most important factors in governing the friction coefficient in Mg alloys. ABSTRACT Data‐driven methods are emerging as
