Digital economy, industrial structure upgrading and green innovation efficiency of family enterprises.

Based on the theory of social capital and strategic revolution, this paper selects 3006 family enterprises in China from 2015 to 2020, establishes a fixed effect panel model, and discusses the impact of the digital economy on the green innovation efficiency of family enterprises from the perspective of rationalization and upgrading of industrial structure. It is found that the relationship between digital economy and green innovation efficiency of family enterprises is inverted U-shaped. The digital economy affects the green innovation efficiency of family enterprises by promoting the rationalization and upgrading of industrial structure. The inverted U-shaped relationship between the two is more significant in the eastern region, the first and the second echelon provinces. Therefore, this paper improves green innovation efficiency of family enterprises from three aspects: digital economy, rationalization and upgrading of industrial structure, so as to finally realize the evergreen and sustainable development of family enterprises. It provides important policy implications for China to realize the green economic transformation and the goals of "carbon peak" & "carbon neutrality" under the global digital tide.
