Notes: The dependent variable is corporate investment (INVt) and is measured by capital expenditure deflated by total assets in year t. TOBt−1 is Tobin’s Q measured by market value of equity plus book value of debt deflated by total assets in year t−1. INDt is board independence measured by the fraction of independent directors in the board in year t. ROAt−1 is firm profitability measured by return on assets in year t−1. LEVt−1 is financial leverage measured by total liabilities deflated by total assets in year t−1. CASt−1 is cash holdings measured by cash and equivalents deflated by total assets in year t−1. SIZt−1 is firm size measured by the natural logarithm of total assets in year t−1. SOEt is the state ownership dummy, assigned 1 if at least 50 percent of shares are held by government agencies and 0 otherwise in year t. *,**,***Significant at 10, 5 and 1 percent levels, respectively
