分析中國經(jīng)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(guān)數(shù)據(jù)，試圖分析我國經(jīng)濟發(fā)

展對股票市場的影響。數(shù)據(jù)來源為CCFR數(shù)據(jù)庫和證監(jiān)會網(wǎng)站。具體分析如下：

一、繪制四個數(shù)據(jù)變量的線性圖，查看2000年到2007年他們各自的走勢。

二、采用最小二乘法(OLS)進(jìn)行分析

七、結(jié)論

本文運用最小二乘法，格蘭杰因果關(guān)系檢驗，相關(guān)性檢驗，單位根檢驗，以

及VAR模型和協(xié)整檢驗，分析r2000年到2007年GDP,成交金額，流通幣值和

居民儲蓄的月度數(shù)據(jù)。通過數(shù)據(jù)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2000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(jīng)濟過熱，通貨膨脹現(xiàn)象有關(guān)，我國居民表現(xiàn)t!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CDP同流通市值以及成交金額之

間的函數(shù)關(guān)系式，并旦通過格蘭杰因果關(guān)系檢驗，得出GDP是流通市值以及成交

金額的格蘭杰因果關(guān)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(guān)系的。

從數(shù)據(jù)到現(xiàn)實，我們回顧幾年我國經(jīng)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(jīng)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(jīng)濟增長，使

企業(yè)的經(jīng)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(fēng)險的降低，這就有利于股票價格的上升。其次，在經(jīng)濟增

長勢頭較好的情況下，將使投資者對未來經(jīng)濟形勢形成良好的預(yù)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(jīng)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。
