Abstract:The fluctuation of financial assets price has been a hot issue of concern to domestic and foreign scholars. On the basis of theoretical analysis on the macroeconomy factors that affect the financial assets price fluctuation, this article sets up the dynamic fitted model between stock index fluctuation and economic growth, price levels, money supply, interest rates, balance of payments. With the empirical analysis, we propose that keeping steady economic growth, maintaining a stable exchange rate policy, formulating a reasonable monetary policy and establishing a sound regulatory system are effective measures to avoid abnormal fluctuation in financial assets price.
