The empirical analysis of technology innovation spillover effects of mineral resources industries in China

As a basic industry,mineral resource industries have strong longitudinal extension and transverse correlation.Based on the 4categories minerals of 8mineral resources industry in China,with the modified input-output model,this paper evaluates technology innovation spillover effect of mineral resources industries with 22 resource industries and related as its basic data.The results show that the technology innovation spillover effects from enterprises are much higher than from research institutions and universities,and the spillover effects of energy resource industry more significant than other types.Continuously strengthening resource industries technology innovation and investment in key type and key link could promote technology innovation level and spillover effects.
