As the first volume of a two-volume set on Chinese economic history, this book investigates Chinese economic development between 1912 and 1949 and unravels the overall level during that time. From the perspective of development economics, the two-volume set studies the economic history and development of China since 1912, with a focus on the quantitative analysis of economic activities. Comprised of two core parts, this first volume, centering on the period of the Republic of China, first describes the historical process and characteristics of the economy at different stages and then looks into the momentum and inner logic that underpin the economic development. The former part covers issues of agriculture, industry, population, and labour force, urbanization, price changes, people’s consumption and living standard, regional difference, etc. The latter part includes discussions on natural and human resources, capital formation and technological progress, the role of government and finance, international trade, and foreign capital. This title will be an interesting read for scholars and students working on Chinese economic history, the Chinese economy, and modern Chinese society.
