According to capital structure pecking order theory,in order to avoid underinvestment due to equity undervaluation because of information asymmetry,the corporate financing order should be internal financing-debt financing-equity financing.Based on ordered probit model and likelihood ratio test,this paper finds that Chinese listed companies'financing order is internal financing-equity financing-debt financing,that is,the listed companies prefer equity financing in China,and this preference is affected more by the cost of capital than information asymmetry.
