Abstract: The strategic emerging industries and the traditional industries are interactive and supplementing each other in their development; a mature strategic emerging industry will transform into a traditional industry, while a traditional industry can turn into a strategic emerging industry through industrial transformation and upgrading. This paper firstly discusses the interactive development modes between the strategic emerging industries and the traditional industries and reveals the characteristics of each mode; then based on the production function, it builds up a model reflecting the contribution of TFP according to indirect R&D, production factors and technology spillover. It also conducts an empirical test by employing a spatial econometric model. The results suggest that strategic emerging industries exert a significant pull effect on traditional industries; from the perspective of technology spillover, the technology spillover effects from strategic emerging industries to traditional industries in North China and Southwest China are relatively significant, while the technology spillover effects from traditional industries to strategic emerging industries are not significant. From the view of input factors, the input increase of labor and capital contributes less to TFP than the increase of R&D and indirect R&D.

Key words: strategic emerging industries; TFP; indirect R&D; spatial weight matrix
