This paper begins with discovering the high degree of association between corporate soft power and enterprise competitiveness, and the joint efforts of the two to construct the enterprise ability through dissecting the connotation and the elements of the corporate soft power. The paper also argues that the private enterprises affect different stake holders through shouldering social responsibilities. And furthermore they can get the value identification of the stake holders, which facilitates the formation of corporate soft power. The operation of some private enterprises (through the positive and negative classical case study) are sound proofs of the argument that corporation that has the awareness of social responsibility helps with the enhancement of its corporate soft power. The findings show that there is a transmittable relationship between taking social responsibility and developing corporate soft power.
