Abstract: From the perspective of biased technology change, we develop a three-factor supply-side equation system with ICT capital, non-ICT capital and labor included. Allowing flexible factor enhanced technological progress, we analyze the impact of China’ s industrial ICT capital biased technology change as well as its consistency between ICT capital and non-ICT capital, and the consistency between the biased technology change and ICT capital deepening on TFP. The results show that against the background of the rapid growth of China’s ICT investment from 2000 to 2016, the technology bias is directed to non-ICT capital and labor. The ICT capital biased technology change is inconsistent with the ICT capital deepening. They jointly suppress the TFP. The consistency of the biased technology change between the ICT capital and non-ICT capital promotes the TFP. For China’ s industrial digitization, we suggest improving the matching of ICT investment with the digital technology roadmap to reverse the ICT capital biased technology decline and further improving the consistency. We also suggest that the appropriate technology improves the consistency between ICT capital biased technology change and ICT capital deepening.
