We explore whether RPT-purchase ratio and RPT-sale ratio would affect firm value after incorporating board structure and financial statement variables, and then reveal the following important findings. First, the firms with either high RPT-purchase ratio or high RPT-sales ratio would all negatively affect firm value, indicating that the firm with higher RPT ratio might not be beneficial firm value enhanced. Second, the firms with well-functioned board structure and better financial performance would have higher firm value as well.
