The Research of R&D Spillover and Total Factor Productivity of China

摘要

By estimating the index of capital services which has double characteristics of material quantity and price with perpetual inventory method and the index of labor input which can indicate quality change with Iterative Proportional Fitting method, we recalculate China's total factor productivity and sources of economic growth from 1978 to 2010 by using growth accounting. Then we test the correlation between R&D spillover and TFP of China on two ways of international trade and FDI. The results show that the improvement of TFP in China depends on the comprehensive benefit of domestic R&D input and international R&D spillover. Independent R&D input is the dominant factor of China's TFP ascension. R&D spillover from international trade and FDI has a time-lag effect on promoting China's TFP, while has a cause-and-effect relationship in the long term.
