The management control system provides valuable information on the managers' needs at different levels of the organization. Today, with changes in the political, social and economic dimensions, the management control system in the public sector also needs to be changed and adapted to new conditions and use new tools to meet stakeholders’ needs. The purpose of this study is to provide a model to investigate the role of the management control system and increase accountability in the public sector administrations and companies. In this regard, the present study explores the role of functions of management accounting in improving the management control system in the public sector. For this purpose, data were collected through interviewing 13 experts in the field of the management control system and functions of management accounting and reviewing related texts, articles and books in this field, and their content was analyzed through grounded theory and content analysis method and MAXQDA 2021 software was used for data analysis in 1399. The findings of this study showed that a management control system, if it has the necessary tools, can play a key role in preventing corruption, increasing transparency and accountability, performance-based budgeting, and performance-based auditing. The existence of a management control system is necessary for any organization; such a system will help identify resource flow, help management in decision making, motivate employees, make decisions related to outsourcing and contracting, reduce service delivery time, and many other issues in organizations, and it will ultimately lead to optimally allocate resources, prevent corruption, and increase legitimacy, transparency and accountability, Therefore, the optimal use of management accounting in the management control system, improves the achievement of organizational goals and the effectiveness of programs

Financial constraints are one of the influencing factors on investment decisions. Financial constraints put firms under pressure to forgo investment opportunities to finance their working capital needs. Moreover, some variables like working capital needs and liquidity of a firm are likely to affect the relationship between these two variables. Hence, this study seeks to examine the effect of short-term credit constraints on the investment of small and medium-sized enterprises (SMEs), firms with different characteristics in comparison with large-sized firms. In addition, this correlation is tested by considering the effect of mentioned moderating variables (working capital and liquidity). The sample of this study includes the firms listed in Tehran Stock Exchange from 2011 to 2018, which are considered as SMEs based on some criteria. Multivariate regression models and E-views software are used to test the research hypotheses. The results indicated that short-term credit constraints negatively affect corporate investment.  It means that constrained firms invest in fewer investment opportunities because of facing source shortages. Moreover, in companies requiring more working capital, the inverse effect of short-term credit constraints on corporate investment is stronger. Such firms suffer from financial problems and are not able to use their investment opportunities. Additionally, this hypothesis that companies with high liquidity can offset u effects of short-term financial constraints on fixed investment, is not confirmed

Iran's Ministry of Petroleum due to empowerment of Iranian companies for executing local mega projects, regional and international markets penetration and upgrading national technology in petroleum upstream industry, predicted a competent Iranian partner called Exploration and Production (E&P) companies, for cooperating with the International Oil Company (IOC) in Article Four of the Cabinet Approval. Now considering the absence of IOCs, it seems that the capacity of other oil contract models to be used by Iranian oil companies should be examined. The purpose of this paper is to investigate the feasibility of Concession agreements’ execution, by an E&P company in Iran’s upstream industry. The research method is descriptive and analytical and governing laws of Iran are reviewed in this study. Since the host government makes the final decision on the conduct of oil operations, it cannot be described as domination of oil resources, and therefore does not seriously contradict the Iran’s Constitution. Furthermore, E&P companies will not be subject to Article 81 of the Constitution. In the Oil Laws, the only restriction on the inflow of foreign capital in the upstream industry of Iran has been observed, which again does not apply to E&P companies. In the Laws of the Five-Year Plans, this restriction of oil laws has been adjusted too much in which it seems that the restriction has also been removed for IOCs. Finally, the investigation shows that there are no major legal barriers in applying Concession agreement in case that the operator is an Iranian E&P company.
