This research aims to study agency costs and tax planning, emphasizing the moderating role of government ownership. Taxation, as the primary means of raising revenue, can help governments achieve their macroeconomic objectives. Paying taxes is one of the most important tasks citizens can perform to provide financial resources for social welfare. In addition, politically connected companies have an opaque operating environment due to government support, resulting in more significant conflicts of interest and higher agency costs. To achieve this purpose, two hypotheses were formulated. To test these hypotheses, a sample of 142 companies was selected from the companies listed in the Tehran Stock Exchange during 2014-2023. A multivariate regression model was applied using the panel data method. The results of the research hypotheses indicate that agency costs and tax planning have a positive and significant relationship. The results also suggest that government ownership does not affect the relationship between agency costs and tax planning

This study investigates the role of digital financial services in enhancing innovation within Iranian sports companies. The research follows a descriptive survey method with a quantitative approach and employs Structural Equation Modeling (SEM) for data analysis. The statistical population includes senior managers, financial managers, and IT managers of sports companies, as well as financial and technology experts in sports clubs and startups. The sampling method was stratified random sampling, and the sample size was determined as 200 participants using Cohen’s method, considering 10 latent variables in the model. Data collection was carried out through two standardized questionnaires with validated content and face validity confirmed by experts. Reliability was assessed using Cronbach’s alpha. The first questionnaire, digital financial services assessment, consists of 15 items across five components (digital financial technology infrastructure, digital payment services, digital banking, digital investment, and digital financial innovation).The second questionnaire, Innovation Assessment in Sports Companies, includes 15 items across five components (product innovation, process innovation, organizational innovation, marketing innovation, and strategic innovation). The Cronbach’s alpha scores were 0.899 for innovation and 0.794 for digital financial services. The findings reveal that digital financial services have a significant impact on various dimensions of innovation, including product, process, organizational, marketing, and strategic innovation. These services enhance transparency, reduce costs, and improve access to financial resources, thereby alleviating financial constraints and fostering innovation capabilities within sports companies
