Supported by new statistical series, this article attempts to improve the explanation of China’s long-term economic growth. It presents the original databases, emphasizing their construction methods, on stocks of physical capital (part 1) and human capital (part 2) for China from 1952 to 2012. Then it offers econometric estimates within the framework of theoretical models, ranging from Solowian specifications to endogenous growth formalizations, with R & D indicators. We find that the productive stocks of physical capital and of human capital, as well as R & D, positively contribute to Chinese GDP growth (part 3).
