By empirical studying on the bases of the power listed companies finance data of 2005-2008 in China, this paper finds that the investment expenditure of China´s power listed companies has a significantly negative relationship with the asset-liability ratio, short-term debt ratio, long-term debt ratio, bank loan ratio, commercial credit ratio, long-term ratio and short-term loan ratio. This indicates that debt can play a constraint role in investment expenditure of the power listed companies, and the constraint effects of the different maturity structures and category structures in debt does not have significant differences.
