The effect of disclosure of intellectual capital and accounting performance on market valuation: evidence from Taiwan's semiconductor industry

Abstract

This study utilises the partial least squares method to establish a causal model depicting the relationship between the disclosure of intellectual capital, accounting performance and market valuation with evidence from Taiwan's semiconductor industry. Our results show that accounting performance, mandatory disclosure of intellectual capital performance and voluntary disclosure of intellectual capital have direct effects on market valuation. These factors also indirectly affect market valuation through the cause-effect interrelationship with one another. Among the indirect relations, the mandatory disclosure of intellectual capital performance is the most fundamental factor which positively affects accounting performance and voluntary disclosure of intellectual capital and then further affects market valuation. The result provides implications for practice for the financial reporting and management of intellectual capital. In essence, the voluntary disclosure of major intellectual capital and the proper management of leading intellectual capital is valuable to market valuation in Taiwan's semiconductor industry.
