| As a trading mode,margin trading(hereinafter referred to as "two financial")has always been widely concerned by all walks of life,but fewer scholars have studied the impact of margin trading on the rights and interests of small and medium investors from the micro level.What is the effectiveness of margin trading mechanism to protect the rights and interests of small investors? If the failure,what is the underlying cause behind it? This is the focus of this study.On the basis of summarizing the status of literature research at home and abroad,based on the basic theory of investor rights and equity and the two financial transaction data of Shanghai and Shenzhen Stock Exchange,this paper systematically uses case theory analysis and event research to investigate the effect of the legitimate rights and interests of small investors from the financial margin trading in the Great Northern Wilderness agricultural Limited by Share Ltd(hereinafter referred to as "the Great Northern Wilderness"),the result of the observation is that margin trading contributes to the damage to the rights and interests of small and medium investors,and then analyzes the reasons for the increase of infringement to the rights and interests of small and medium investors in the Great Northern Wilderness.Finally,some suggestions are put forward.The analysis of the reasons is mainly from the rationality of the selection of the two standards and the investors themselves.The rationality of choosing the margin trading's targets is also analyzed from the financial early warning and the ownership structure of the company.In view of the conclusion that the company's financial situation is extremely unstable in 2011,we have carried out a thorough and comprehensive analysis on the three aspects of the qualitative,quantitative and deep aspects.The results show that the company's operating costs are too fast to rise,the growth is not sustainable and the investment is excessive,which is the root cause of the loss of the investor's interests.Finally,we draw the conclusion that we should carefully select the financial warning and warning degree as the largest company of "middle police" or above and state-owned shares.It is of great theoretical and practical significance to explore these problems to enhance the understanding of other standard companies in the two thawing,to guide investors to participate rationally in the two thawing transactions,to help the relevant departments to explore the factors that promote the better effectiveness of the financing margin mechanism,to improve the two thawing trading machine system and to further deepen the reform of the financial system. |
