This book presents an in-depth exploration of China's unique journey in informatization, tracing the nation' s path from the founding of the People's Republic to its current status as a global digital powerhouse. Unlike other works that primarily offer statistical overviews, this book provides a comprehensive analysis of China's strategies, policies, and achievements in the fields of digital economy, industry, agriculture, e-commerce, and e-governance. It goes beyond the typical narrative, integrating perspectives from Marxist political economy and Xi Jinping's economic thought on socialism with Chinese characteristics, delivering a distinct ideological context often overlooked in discussions on China' s digital development. Written by Zhu Yan, a prominent researcher in Marxist political economy, the book dives into not just the historical and technological facets, but also the socio-political implications of China's digital transformation. It highlights both the successes and challenges of China's informatization, offering a forward-looking analysis that is invaluable for policymakers, business leaders, academics, and students alike.
