Intellectual Capital and Business Performance: New Model

Intellectual Capital (IC) is currently considered as a main source to obtain a competitive advantage in the knowledge economy. Many researchers and practitioners are trying to define and propose its various components. Even to propose several models to measure the intellectual capital and how to better manage tangible and intangible companies assets. The purpose of this thesis is to study the impact of IC on the performance of Algerian companies and this by two models, the model of Sharbati A,Jawad S & Bontis. N (2010) and the model of Choudhury.J (2010). The main result shows that human capital has a positive influence but a weak relationship with the company's performance. The new proposed model shows that there is an intermediate variable and a moderate variable affecting the relationship between the IC and the satisfaction of the client. The review of this model through 103 employees in four Algerian companies shows that human capital, social capital, organizational capital and service / product quality have a positive influence on the customer satisfaction.
