On 5 March 2019, Premier Li Keqiang pointed out in the 2019 government work report released by the State Council that over the past year, the in-depth implementation of the innovation-driven plan has further improved innovation capacity and efficiency. The core of implementing the goal of “innovation-driven development” is to make full use of the technological characteristics of digital products to promote high-quality innovation. The article empirically analyses the impact of digital product imports on the innovation performance of listed companies by using data from the database of industrial enterprises, the customs database and the patent application data of the State Intellectual Property Office from 2006~2015. The results of the study show that in the benchmark regression results, the import of digital products of enterprises is conducive to the improvement of enterprise innovation efficiency. Finally, three policy recommendations are proposed based on the results of theoretical and empirical analyses.
