The Trends and Gaps in the Sensitivity of Investment to Cash Flow: Evidence from China

The ability of using internally generated funds to finance investments affects corporate sustainability. We empirically examine trends and gaps in the reliance of company's investments on internally generated funds. We collect financial data of Chinese listed companies from 1998 to 2020, use corporate cash flow as a proxy for internally generated funds, control for corporate investment opportunity Q, and specify a two-way fixed effects model of investment on cash flow. We find that investment-cash flow sensitivity exhibits a decreasing trend over time; firm size, government equity, and the HP and WW indices effectively explain the gaps in the sensitivity of investment to cash flow between two types of firms with tighter and looser financing constraints, but cash dividends do not explain the gaps; and the gaps in the sensitivity of investment to cash flow are narrowing in the long term. These empirical findings indicate that compared to external funding, internal funding is becoming less important in supporting a firm's investment-induced sustainability.

Automated summary

The ability of companies to finance investments using internally generated funds has an impact on corporate sustainability. Empirical research conducted on the financial data of Chinese listed companies from 1998 to 2020 shows a decreasing trend in the sensitivity of investment to cash flow. Factors such as firm size, government equity, and the HP and WW indices explain the gaps in investment-cash flow sensitivity between firms with different financing constraints, while cash dividends do not. Furthermore, the gaps in investment-cash flow sensitivity are narrowing in the long term.
