Does market competition promote innovation efficiency in China's high-tech industries?

Despite extensive discussion about the relationship between market competition and innovation performance, the impact of market competition on the innovation efficiency of high-technology industries in a transitional economy is still unclear. The article is based on panel data of 17 subsectors of China's high-tech industry spanning the 2001-2016 period. Using stochastic the frontier analysis model, we empirically test the impact of market competition on two-stage innovation efficiency from the perspective of the industry. The results indicate that market competition and firm scale have positive and significant effects on the efficiency of two-stage innovation, the effects of industry export intensity and government intervention on R&D efficiency are negative, but the effects are different for the efficiency of the commercialisation of technology. Based on the results of the empirical analysis, this paper compares the trends and the differences between R&D efficiency and commercialisation efficiency, and then uses cluster analysis to reclassify China's high-tech industries into three categories, thus revealing the disconnect and imbalance within China's high-tech industries. At the end of the article, we present some possible policy recommendations.
