    Abstract: 本研究利用台指期貨委託檔、成交檔及揭示檔等資料,使用Parkinson (1980)波動度計算公式,並以委託單積極度、委託單離散程度及交易成本作為代表流動性的指標來觀測期貨市場流動性對波動度的影響,並進一步將交易人區分為外資、期貨自營商、國內法人及散戶,研究其流動性對波動度的影響。
    實證結果發現,散戶為流動性主要提供者,當下單越積極則影響市場波動度越大;外資為理性交易者,其下單行為不會造成價格劇烈波動;在全市場不分交易人的情況下,本文所使用的流動性指標對波動度皆有顯著關係。
    In this paper, we observe the futures market liquidity on the impact of volatility by using the order of TAIEX, the Parkinson (1980) volatility to calculate the formulas, with the representative indicator of liquidity which including the Aggressiveness of orders, the Dispersion of orders and transaction costs, using data from the order of TAIEX, the order of market and the reveal order. Furthermore, we study the liquidity on the impact of volatility by dividing the trader into foreign investment, futures dealers, domestic institution and individual.
    With the empirical results, we found that the individual is the main provider of liquidity, trading more aggressive making more future market’s volatility, foreign investment is the rational trader and it can’t cause the strict price volatility by its trading. Without dividing traders from all markets, the liquidity factor we used have strong relationship with the volatility.
