The presence of multiple actors in the field of urban planning and their different interests, along with the lack of sufficient attention from planning authorities to optimal land use planning, potentially leads to conflicts among stakeholders. The aim of the present research is to identify and analyze the factors influencing the emergence of conflicts in the process of urban land use planning. The present study is a combination type and falls into the category of sequential-exploratory research. Therefore, qualitative and then quantitative data are collected and ultimately both are analyzed. In the first part, the meta-synthesis method (qualitative) is used to present a conceptual model of managing conflicting interests of stakeholders, and in the second part, the survey method (quantitative) is used to explore the relationships between components in the emergence of conflicts. The key components of the conceptual model include economic conflict, public and private interest conflicts, value conflicts, participation reluctance, procedural conflict, and organizational conflict, with regression equations indicating the impact of 24.7%, 21.1%, 19%, 17.6%, and 14.7% of these components on the emergence of conflicts. To operationalize the conceptual model and explore causal relationships, a researcher-made questionnaire aligned with the findings of the first step was used. The statistical population includes managers and decision-makers in urban affairs and residents of Mashhad city. The sample size was estimated using the Cochran formula, considering a 0.05 error rate, resulting in 383 individuals as the sample size. The results indicate support for all components, with the economic conflict component identified as the most influential factor in the emergence of conflicts in the urban land use planning process.
