The purpose of this research is to design a model for the economic development of theater. In terms of purpose, this study is applied, and according to the method of data collection, it is descriptive-survey. The data collection method in this research is quantitative. Quantitative data were collected using a researcher-developed questionnaire. The statistical population of this study includes artists active in various fields of theater, including directors, producers, actors, theater venue managers, and graduates of theater studies. Since accurate statistics regarding the statistical population of this research are not available, it was considered unlimited; therefore, based on Cochran's formula, a sample size of 384 individuals was determined and selected using simple random sampling.Furthermore, the discriminant and convergent validity of the questionnaire indicated its appropriate validity. Data analysis was performed using structural equation modeling with the SmartPLS4 software. The results showed that the model for the economic development of theater includes causal conditions , contextual factors (including physical infrastructure, education and research for training specialized human resources, and professional and specialized infrastructure), intervening factors, strategies (including infrastructure development, education and empowerment, financial support for productions, marketing and advertising, and international, national, and local collaborations), and outcomes (including economic growth, strengthening of cultural components, and the development of cultural, social, artistic, and political tourism). Given that all factor loadings exceeded 0.4, this indicates the model's appropriateness, and it can be stated that the model has a strong fit.
