Abstract:In the context of the knowledge economy, the intellectual capital of a company has largely influenced or even determined its market competitiveness. But how does intellectual capital work in the enterprise? Past research tends to ignore its internal mechanism of action, so that the relationship between the dimensions of intellectual capital is still a "black box." Therefore, on the basis of previous research, this paper starts with the four-dimensional structure of intellectual capital and finds data from 206 Chinese companies: Intellectual capital not only directly affects organizational performance, but also indirectly affects organizational performance through other dimensions. There are also interaction effects between structural dimensions, which affect organizational performance to varying degrees.
