Decision rights are a core element of governance, representing the authority to make decisions. Such decision rights are closely related to the performance of organizations and decision-makers, and the impact on performance may vary depending on the fit between the characteristics of decision-makers and decision rights. This study focuses on the motivation of decision-makers among their characteristics, and seeks to determine how the fit between regulatory focus—which has received the greatest attention in this field recently—and decision rights affects performance. To achieve this objective, this study conducted a bilateral survey targeting CEOs and sales managers of domestic startup firms, and collected questionnaires from a final sample of 108 firms. Hierarchical regression analysis was performed on these data, and the results showed that sales managers' promotion focus had a positive effect on quantitative performance, while prevention focus had a positive effect on qualitative performance. Next, sales managers' promotion focus had a positive effect on quantitative performance through its interaction with decision control rights, while prevention focus had a negative effect on qualitative performance through its interaction with decision control rights and a positive effect on qualitative performance through its interaction with decision management rights.
