With the booming development of the digital economy, digital transformation has become an industry trend, and the demand for digital talents and skills in the job market is at an all-time high. As an emerging form of human capital, how are digital skills related to traditional human capital, and what are their differences? The first four chapters of this book comprehensively review the evolution of the connotation of human capital and the emergence of digital human capital. Against the current backdrop of the digital economy, which types of digital skills offer more employment opportunities and bring higher returns? Chapters five and six attempt to answer these questions using data from employment markets in Beijing, Shanghai, and Shenzhen, revealing the overall demand for digital skills in the job market, the demand for different types of digital skills, and corresponding income levels. These findings are of significant importance to workers, various employers, and policymakers. This book suits students and scholars engaged in human resources research, as well as HR practitioners seeking to deepen their theoretical understanding.
