This paper takes A-share listed companies in Shanghai and Shenzhen between 2014 and 2018 as the research object, and empirically tests the relationship between information technology investment and the effectiveness of internal control and the moderating effect of institutional investors’ shareholding on the two. The study finds that information technology investment can significantly improve the effectiveness of internal control, and the increase in the shareholding ratio of institutional investors will enhance the positive effect of information technology investment on the effectiveness of internal control. However, further research by industry finds that: for labor-intensive enterprises, neither the impact of information technology investment on the effectiveness of internal control nor the moderating effect of institutional investors ’shareholding on the two are significant; while information technology investment of capital-intensive enterprises and technology-intensive enterprises has positive improvement effect on the effectiveness of internal control, and institutional investors ’shareholding will enhance the improvement effect of information technology investment on the effectiveness of internal control.

With the increase of country investment in education, the university fund of infrastructure and experimental practice construction continues to grow, the university sources of fund and the use of fund present multiplication, economic activity presents more complex. Therefore, it provides new requirements to strengthen the internal control of university and raise efficiency in fund utilization. According to the COSO, the paper combines internal control-integrated framework and Internal Control Regulations of administrative institutions. The paper establishes an internal control system of bidding procurement in university from role orientation and organization construction, process control and information transmission, expert selection and management system, information construction and data collection, based on problem and characteristic of bidding procurement in university. The internal control system not only effectively promotes risk prevention and control measures of bidding procurement in university, regularizes operation of internal power, but also improves the standard of internal administration in university.

In a wind tunnel test, the tail model support system of cantilever beam structure will produce vibration under the wind load, which may threaten test safety and affect test results. In order to suppress the vibration of the model and support system, an active vibration control method is studied and applied. Among them, the actuator of suppression system adopts piezoelectric material, and the control system is based on adaptive internal model control algorithm. This paper analyzes the structure and working principle of the adaptive internal model control algorithm, and introduces the model parameter identification in training mode and the adaptive adjustment process of control parameters in experimental mode. A control system based on the adaptive internal model control algorithm is established. A signal generator is used to simulate the excitation of the system on the ground simulation platform. The control algorithm is verified as the input of the control system. Combined with the wind tunnel test, the control effect of the system is verified under actual conditions. The results show that the active vibration control system based on adaptive internal model control algorithm can reduce the vibration by more than 70%. [ABSTRACT FROM AUTHOR]

In recent years, China' s economy has been developing steadily and the investment in higher education has been increasing. College government procurement runs through the whole process of school economic activities. It is an important part of college asset management and the foundation of college survival and development. Government procurement is the basic link to maintain the normal order of teaching, scientific research and management. The internal audit of colleges and universities adopts the systematic and normative method, then through the independent and objective supervision and evaluation of the internal control of universities, the goal is to identify and prevent errors and fraud, and improve the use efficiency of funds. This paper analyzes the audit supervision of current government procurement, and puts forward solutions and improvement measures, scientific and reasonable suggestions based on the actual situation of government procurement of Huaqiao University, so as to further optimize the audit supervision of government procurement.

Using the data of A-share listed companies from 2011 to 2016 in Shanghai and Shenzhen, we establish a panel threshold model which the threshold variable is internal control, and analyse the nonlinearity relationship between dividend and agency cost. The result shows:There exist threshold effects between dividend and agency cost based on internal control. Cash dividend can reduce agency cost when internal control quality is higher than the threshold, otherwise, cash dividend will no longer have any effect. That means, a valid internal control is the foundation of dividend governance function. Furthermore, the descriptive statistics result implies that, companies with higher internal control quality than threshold are popular. This paper proofs that agency theory is effective in Chinese market, and higher internal control quality higher propensity to pay. So we disagree with the previous hypothesis of "result" and "substitution" between internal control and dividend. [ABSTRACT FROM AUTHOR]
