How enterprises can make reasonable decisions on their water environment behavior based on the external environment and their own factors is of great significance for scientifically and effectively designing water environment regulation mechanisms. Based on optimal control theory, this study investigates the design of contractual mechanisms for water environmental regulation for small and medium-sized enterprises. The enterprise is regarded as an independent economic entity that can adopt optimal control strategies to maximize its own interests. Based on the participation of multiple subjects including the government, enterprises, and the public, an optimal control strategy model for enterprises under contractual water environmental regulation is constructed using optimal control theory, and a method for calculating the amount of unit pollutant penalties is derived. The water pollutant treatment cost data of a paper company is selected to conduct empirical numerical analysis on the model. The results show that the increase in the probability of government regulation and public participation, as well as the decrease in local government protection for enterprises, can achieve the same regulatory effect while reducing the number of administrative penalties per unit. Finally, the implementation process of contractual water environmental regulation for small and medium-sized enterprises is designed.展开更多

The United States of America responded to this discussion with the ＂Sarbanes-Oxley Act＂, while the European Union decreed the directive 2006/43/EC. The mentioned directive updated the statutory provisions for the professional guild of auditors to increase the quality of audits. In detail, it demanded an external quality-control-system combined with public supervision for the profession of auditors to ensure a better quality. Due to this fact, the audit companies now have to fulfill a large range of requirements to provide evidence of their consistent auditing-quality and furthermore of the quality standards within their company. Since many small and medium-sized companies are not able to fulfill these new requirements, the number of small and medium-sized audit companies decreases noticeably. This paper discusses the research results on the effects of external quality control^given by law---on the auditor market in Germany focusing on small and medium-sized audit companies. Additionally the research examines that, if the external quality control, which was one of the justifications of the conversions of the EU-directive 2006/43/EC is able to increase the quality in audit companies at all. Therefore it needs to be tested whether there is a uniform and fits all approach of quality in audits. The research questions and the tests were analyzed scientifically and confirmed in several expert interviews with four different expert groups in Germany.展开更多

文摘The small and scattered enterprise pattern in the county economy has formed numerous sporadic pollution sources, hindering the centralized treatment of the water environment, increasing the cost and difficulty of treatment. How enterprises can make reasonable decisions on their water environment behavior based on the external environment and their own factors is of great significance for scientifically and effectively designing water environment regulation mechanisms. Based on optimal control theory, this study investigates the design of contractual mechanisms for water environmental regulation for small and medium-sized enterprises.
