In this research, due to the importance of the stakeholders' perceptions in the process of drafting and approving the law, the changes in the perceptions and preferences of the stakeholders in the process of approving the knowledge-based production jump law have been investigated and analyzed. Based on this, an exploratory study was conducted with a qualitative case study strategy. After reviewing all the policy texts and related laws and regulations, the representatives and stakeholders in the legislative, executive and public and non-governmental bodies who played a role in the approval process of the law on the jump of knowledge-based production have been interviewed. The category-based content analysis method was used to analyze the research data.
