Using the relevant data of Chinese listed companies from 2010 to 2013, this paper makes an exploration on the relationship between top managerial power, financing structure and resources allocation of bank credit. The results indicate that management structure of the company and the managerial power are the important reasons for company's financing policy choice and bank credit resource allocation, when the company's management have greater top managerial power, the firm lend more short-term loan, the company's management power have a positive relation with short-term borrowing structure. Under the effect of debt constraint, in view of personal tenure and control desire, the management will make decisions influencing the corporate financing decision. In corporate bank credit financing, bank credit financing scale is negatively correlated with company managerial power. Namely, the more power the management has, the less resources of bank credit. We also find that the company's management structure power and the owner power have a significant effect on corporate credit decision-making.
