Abstract:This paper systematically and theoretically sorts out the influence path of ICT to national innovation ability, which is mainly achieved through the driving of technology, the accumulation of ICT human capital and the construction of ICT public infrastructure. Through empirical analysis of relevant data from 1997 to 2016, this paper finds that ICT public infrastructure construction has the strongest independence in influencing national innovation capacity, which means strengthening ICT public infrastructure construction can directly and effectively improve national innovation capacity and under the synergy of technology driving factors, this promotion effect will be significantly improved. Technology-driven element shows higher degree of dependence on the ICT public infrastructure construction than the degree of dependence on the accumulation of ICT human capital, and the accumulation ICT human capital must cooperate with the other two elements to enhance the national innovation ability.
