Abstract: The manufacturing sector is a leading force in China’s industrial growth. In this paper, DEA-Malmquist index is applied to measure TFP changes in China’s 20 manufacturing industries from 1997 to 2005. And in order to compare the disparities of technological change, the manufacturing industries are divided into three sectors, non-durable consumer goods, intermediate inputs, capital goods and durable consumer goods. In this way, characteristics of technological change of different industries are reflected. The results show that the TFP growth of manufacturing sector is 3.76% on average, of which technological progress is the main reason. In the three sectors, the TFP of non-durable consumer goods grow fastest, capital goods and durable consumer goods performance the best as a whole, low scale efficiency of the intermediate inputs industries inhibits the growth of technological efficiency, thus hampering the sector’s TFP growth.
