Digital industrialization and industrial innovation efficiency:Estimation based on TrueFE SFA model
The 20th National Congress of the Communist Party of China emphasized the need to accelerate the implementation of the development strategy driven by innovation,improve the efficiency of scientific and technological investment and the level of transformation of scientific and technological achievements.Based on the connotation of core industries of digital economy,this study constructs a relevant indicator system and uses the principal component analysis method to calculate digital industrialization index,which reflects the development level of regional core industries of digital economy.On this basis,using provincial panel data from 2003 to 2020,this study empirically tests the impact of the development of core industries of digital economy on the innovation efficiency of high-tech industries.The research finds that:(1)Since 2003,China's core industries of digital economy development index has shown a significant upward trend,but regional differences and"digital divide"are significant,with the eastern region superior to other regions;(2)Digital industrialization can significantly improve the R&D efficiency and achievement transformation efficiency of high-tech industries.However,this empowerment mainly comes from the application of digital technology and digital factor driven industries,while the effects of digital product manufacturing and service industries are relatively small;(3)The impact of digital industrialization has significant regional heterogeneity,with a greater promotion effect on the R&D efficiency in the west and northeast regions,and transformation efficiency of scientific and technological achievements in the east and central regions;The development of local digital core industries has a weak spatial spillover effect on neighboring regions.(4)Efficiency estimates based on a true fixed effect stochastic frontier model indicate that since 2003,there has been an obvious upward trend in the R&D efficiency and transformation efficiency of China's high-tech industries,with regional disparities narrowing.Finally,based on the research findings,relevant suggestions have been proposed.
