However, there is not enough research on the mutual influence between ETFs and constituent stocks' liquidity. This paper aims to explore the mutual influence between ETFs and constituent stocks' liquidity through panel analysis based on reverse selection cost. Specifically, the study will be divided into the following parts: first, by collecting data, constructing an investment portfolio including ETFs and constituent stocks, and calculating their liquidity respectively. Secondly, using the panel regression analysis method to study the interaction between ETFs and constituent stocks' liquidity.
