Cash flow uncertainty, financial constraints and R&D investment

Based on the data from Chinese listed companies of Shanghai and Shenzhen stock markets between 2005 and 2016, we systematically examine the relationship between cash flow uncertainty and R&D investment, and further research the moderating effect of financial constraints on the association between the two. Our empirical results find that R&D investment decisions tend to be more conservative and cautious due to cash flow uncertainty, which is not conducive to innovation efficiency. Firms with higher cash flow uncertainty invest more cautiously in R&D innovation, whereas firms with lower cash flow invest more boldly in R&D innovation. Financial friction may exacerbate the negative impact of cash flow uncertainty on innovation activities. Strategic cash holding can help firms better deal with the risks caused by cash flow uncertainty. In provinces with high marketization, the market competition intensifies, resulting in more significant cash flow uncertainty.
