Abstract: In the background of China’ s plan to develop “strategic emerging industries”, this paper introduces a new concept of “key industries” with its internal logic, and studies its theoretic significance for economic growth, based on the definition of “basicness” in technical structure theory and technological progress potential. Furthermore, this paper proposes a quantitative method for the identification of key industries on the basis of input-output table data. This method also can be used for selecting key industries for industrial policy.The quantitative analysis based on matrix triangularization shows that China’ s key industries include communication devices, computers and other electronic equipment manufacturing, general and specific equipment manufacturing, and transportation equipment manufacturing. Meanwhile, we also calculate the competitiveness indices for those sectors and compare them with other countries. The results show that in China the sectors of “general and specific equipment manufacturing” and “transportation equipment manufacturing” are competitive, while the competitiveness of the sector of “communication devices, computers and other electronic equipment manufacturing” is relatively low.
