Purpose-On the health care industry, the paper aims to study the effects of intellectual capital, identify using an input-process-output concept of human, customer, innovative and process capitals, on company performances. Design/methodology/approach-From a resource-based and intellectual capital perspective, the structural path model is applied to financial data to analyze the six-value creation relationships among the four components of intellectual capital, as well as the causal effects of intellectual capital on company performance. Findings-Empirical findings suggest a significant relationship between intellectual capital and company performance. These results also suggest that innovative capacity and process reformation shall be considered first, and through the human value-added of human capital, firms can improve their company's performance. Originality/value-There have been many arguments as to whether intellectual capital is quantitatively measurable. This paper provides a tangible means of quantifying intellectual capital.

Purpose-The purpose of this paper is to examine the relationship between firms' value drivers and their intellectual capital (IC). Design/methodology/approach-The health care sector (GICS 35) firms listed in the S&P500 were used to build a research censoring Tobit model by adopting financial data to determine value drivers. Findings-The results of the study show that innovation capital, customer capital and human capital are significant positive drive factors for firms to create more IC and hence more intangible value. Process capital exerts moderating effects on IC; organizations with greater process capital must raise customer capital to enhance intellectual value. Originality/value-This is the first empirical study that uses a censoring Tobit model and tests of the association between competitive advantage and the value drivers of firms. This research successfully combines management perspectives with financial data to describe the value drivers of firms.
