分析中國經濟發(fā)展對中國股票市場的影響

本文通過分析2000年到2007年各月股票市場流通市值(value),成交金額

(turnover),GDP現(xiàn)價和居民儲蓄(saving)的相關數(shù)據，試圖分析我國經濟發(fā)展對

股票市場的影響。數(shù)據來源為CCFR數(shù)據庫和證監(jiān)會網站。具體分析如下：

一、繪制四個數(shù)據變量的線性圖，查看200()年到2007年他們各自的走勢。

二、采用最小二乘法(0LS)進行分析

三、格蘭杰因果檢驗

（1）檢驗GDP同流通市值之間的格蘭杰因果關系

滯后期為10,P（F>1.08348尸0.38941,P（F>2.67705）=0.00904,所以原假設

"TURNOVER不是GDP變化的原因“被接受，但原假設“GDP不是TURNOVER

變化的原因”被拒絕。

（2）檢驗GDP同成交金額之間的格蘭杰因果關系

“VALUE不是GDP變化的原因”被接受，但原假設“GDP不是VALUE變化的

原因”被拒絕。

七、結論

本文運用最小二乘法，格蘭杰因果關系檢驗，相關性檢驗，單位根檢驗，以

及VAR模型和協(xié)整檢驗，分析了200()年至1」20()7年GDP,成交金額，流通市值

和居民儲蓄的月度數(shù)據。通過數(shù)據分析，我們可以發(fā)現(xiàn)我國近七年的GDP保持

較快的增長，并且增長勢頭良好。我國的股票市場在2()00年到2005年之間，無

論在流通市值還是在成交金額方面，基本保持平穩(wěn)的發(fā)展，2006年基本上算是

一個突變點，股市出現(xiàn)了快速增長，甚至可以用激增來形容。這與我國2006年

和2007年經濟過熱，通貨膨脹現(xiàn)象有關，我國居民表現(xiàn)出了巨大的投資熱情，

同時股票市場非常繁榮，使得我國國民炒股比率迅速增加，這帶動了流通市值和

成交金額的顯著增長。本文通過使用最小二乘法，找出了GDP同流通市值以及

成交金額之間的函數(shù)關系式，并且通過格蘭杰因果關系檢驗，得出GDP是流通

市值以及成交金額的格蘭杰因果關系。最后運用時間序列的方法，分析了GDP

同流通市值及交易金額的協(xié)整檢驗，通過分析，我們可以得出他們之間是存在協(xié)

整關系的。

從數(shù)據到現(xiàn)實，我們回顧幾年我國經濟的發(fā)展情況，從2000年到2007年,

我國的GDP都保持持續(xù)、穩(wěn)定、高速的增長。在持續(xù)、穩(wěn)定、高速的經濟增長

情況下，我國的股票市場也逐步的完善和繁榮。首先，伴隨總體性的經濟增長,

使企業(yè)的經營環(huán)境不斷改善，上市公司的利潤總體水平也會持續(xù)上升，從而帶來

股息紅利的增加和投資風險的降低，這就有利于股票價格的上升。其次，在經濟

增長勢頭較好的情況下，將使投資者對未來經濟形勢形成良好的預期，提高對證

券投資的積極性，從而增加對股票投資的需求，這也有利于股票價格的上升。最

后，隨著GDP的增加，個人的可支配收入也會同步上升，個人收入的增加必然

會在客觀上增加對證券投資的資金來源，實際上等于是擴大了對證券的需求，這

也是有利于證券價格的上升。因此我們可以看出，我國經濟的穩(wěn)定健康快速的發(fā)

展對于我國的股票市場起到了積極的推動作用。
