| 摘要自20XX年下半年以来，我国证券市场交易日趋活跃，上证指数与股票价格大幅上升。分析影响市场价格的资金来源诸因素对于解析证券市场现象具有突出的意义。论文选取我国证券市场中常用的、也是最重要的上证指数作为分析对象，对证券指数与利率、汇率、以及融资融券规模因素间的关联程度进行了综合分析。 本文在回顾相关研究文献的基础上，首先从理论方面归纳了利率、汇率、融资融券对上证指数的作用机制。然后从实证分析角度入手，以2014年9月至2015年4月的上证指数、利率、汇率、融资买空、融券卖空为研究对象，建立VAR模型，并运用协整分析、脉冲响应函数以及方差分解的方法，探索了利率、汇率以及融资融券规模与上证指数之间的关系。结果表明，上证指数与相关影响因素间存在着长期均衡的关系；利率、汇率对上证指数有影响，但是作用不大；上证指数在此期间的持续上涨过程中，融资融券加剧了证券指数的波动。30240 关键词 上证指数 影响因素 VAR模型 毕业论文外文摘要 Title The Analysis of Market Related Factors of the Recent Volatility in the Shanghai Composite Index --Comparison of the Effects of Interest Rate, Exchange Rate and Margin Abstract Since the second half of 2014, trading in China's securities market has become increasingly active, the Shanghai index and the stock price rose sharply. Analyzing the factors that can influence the capital source of market price is significant for us to analyze the phenomenon of stock market. This paper used the Shanghai composite index which is the most common and the most important index in China's securities market as the research object, the correlation degree of stock index and interest rate, exchange rate, and margin scale factors are analyzed. This paper is based on a lot of literature. First, analyzing the mechanism of interest rate, exchange rate and margin of Shanghai index from the theory. Then, starting from the empirical aspect, using the Shanghai stock index, interest rate, exchange rate, financing to buy and sell securities on 2014 September to 2015 April as the research object, establishing the VAR model and using cointegration analysis, impulse response function and variance decomposition method, to explore the relationship among interest rate, exchange rate, margin and Shanghai stock index. The results show that there is a long-run equilibrium relationship between them; the interest rate and the exchange rate has a impact on the Shanghai index, however, does little; in the process of rising continuously of the Shanghai composite index, the margin exacerbated the fluctuations of Shanghai Composite index.
