Abstract:
Green technology innovation is an important driving force and source to promote my country’s high-quality development, and it is the core path to achieve sustainable development. This paper uses my country’s provincial panel data from 2016 to 2020 to study the effect of mechanisms of R&D investment on green technology innovation, and introduces the level of digitization as an important influencing factor. Using the panel threshold model, it discusses the effect of mechanisms of R&D investment on green technology innovation. The study found that when the digitalization level of the region is low, the R&D investment cannot clearly define the type of innovation, and increasing the R&D investment will not necessarily improve the green technology innovation capability; but when the regional digitalization level is relatively high, the R&D investment can effectively promote the green technology innovation. Therefore, it is necessary to improve policies to encourage enterprises to increase R&D investment and enhance the driving force of innovation; and promote the coordinated development of digital foundation, digital investment, digital literacy, digital economy and digital application, and promote the deep integration of digitalization and green technology innovation.
