Municipalities and waste management organizations of the country have, in recent years, outsourced urban services activities as one of their most important duties to the private sector companies. Studies have shown that sometimes by outsourcing such activities, the level of services to the customers and citizens is reduced. Regarding the short time that has passed from privatization of these activities, much studies and investigation have not been conducted concerning the performance of such companies; this point makes clear the necessity to investigate this issue. In this research, the relationship between transformational leadership and competitive environment and marketing trends with organizational performances in urban services and waste management companies has been investigated. The present research is applied in terms of purpose, and it is descriptive of correlation type in terms of method. The statistical population of the research is composed of the executive companies of waste management in 31 centers of the provinces, that the sample size have been determined out of 121 companies, using Cochran method, and 191 questionnaires were collected. The data collection tool is a questionnaire that structural equation modeling and multiple regressions were used for its analysis. The results obtained from testing the hypotheses showed that competitive environment and marketing trends affect organizational performances (financial and non-financial), and transformational leadership only affects financial performance of the companies through competitive environment and non-financial performance, and these results indicate that competitive environment and marketing trends as a powerful variable affect the relationship of transformational leadership with organizational performances
