The role of applying corporate governance for listed companies in determining the effect of Book Value and Earning Per Share on the Market Value of companies: An applied study of a sample of companies listed on the Amman Stock Exchange for the period (2013-2021).

The market value of companies is a central focus for all stakeholders, and it is often estimated based on the available information in financial reports. Corporate governance is one of the key tools that govern the quality of financial reports and the information they contain, which decision-makers rely on. This research aims to address the research problem related to the direction and magnitude of the relationship between book value and earnings per share in determining the market value of companies, before, during, and after the implementation of corporate governance in the Amman Stock Exchange for the period (2013-2021). The study sample consisted of (479) observations from the financial sector. The research aimed to highlight the significant differences in the market value response before and after the implementation of corporate governance in the examined stock exchange. The results concluded that there is a significant variation in the impact of the independent variables, represented by the book values of companies and earnings per share, on the market value of shares before and after the adoption of corporate governance. Additionally, corporate governance contributes to enhancing the market value estimation of these companies, but corporate governance does not have a clear role in determining the market value in the examined field.
