资本成本率是指企业筹集和使用资本所付出的代价。具体来说，它包括筹资费用和用资费用两个方面。资本成本率是企业进行投资决策、筹资决策以及财务分析的重要依据。

资本成本率的计算公式为：资本成本率 = 筹资费用 / 筹资总额。其中，筹资费用是指企业在筹集资本过程中所支付的各种费用，如发行股票、债券所支付的发行费用、律师费、公证费、担保费等等；筹资总额则是指企业筹集的资本总额，包括股票和债券的发行总额、股东权益总额等等。

资本成本率的高低可以反映出一个企业对于资本的利用效率以及市场对于企业的认可程度。如果一个企业的资本成本率较高，说明该企业对于资本的利用效率较低，同时也说明市场对于企业的认可程度较低，企业需要付出更高的代价来筹集和使用资本。因此，企业需要不断优化自身的资本结构，降低资本成本率，提高企业的盈利能力和市场竞争力。

The capital cost rate refers to the cost paid by an enterprise for raising and using capital. Specifically, it includes the raising expenses and using expenses. The capital cost rate is an important basis for enterprises to make investment decisions, raise capital decisions, and financial analysis.

The calculation formula of the capital cost rate is: capital cost rate = raising expenses / total amount of raising capital. Among them, raising expenses refer to various fees paid by the enterprise during the process of raising capital, such as issuing fees for stocks and bonds, lawyer fees, notary fees, guarantee fees, etc.; the total amount of raising capital refers to the total amount of capital raised by the enterprise, including the total issue amount of stocks and bonds, total shareholder equity, etc.

The level of the capital cost rate can reflect the efficiency of a company's use of capital and the market's recognition of the company. If a company's capital cost rate is high, it means that the company's utilization efficiency of capital is low, and it also indicates that the market's recognition of the company is low, so the company needs to pay higher costs to raise and use capital. Therefore, companies need to continuously optimize their capital structure, reduce the capital cost rate, and improve their profitability and market competitiveness.
