Research and Development Investment and Earnings Quality Based on Regression Analysis

Based on the big data of Chinese listed manufacturing firms, we examine the relationship between research and development (R&D) investment and earnings quality. We construct a regression model and find that corporate R&D investment has a positive effect on earnings quality. R&D investment is useful to repress earnings management motives and thus improve earnings quality in listed manufacturing firms in China. And this positive correlation is more significant in state-owned firms than that in non-state-owned firms.
