Abstract
Based on the trading data of A-share listed companies held by ETFs
and the shareholding data of exchange-traded funds during 2011-2022 in China
stocks markets, this paper uses the dynamic panel differential GMM model to
study the shareholding ratio of exchange-traded funds and the impact of its
changes on the liquidity of the underlying stocks. First, all the samples were
regression and empirical results were analyzed. Then, the main board of
Shanghai and Shenzhen, small and medium-sized board and growth enterprise board
stocks were respectively regression to draw conclusions, and the robustness of
the above research was tested. In the end, two main conclusions are drawn from
the above research: (1) There is a significant positive correlation between the
shareholding ratio of ETFs and stock liquidity, that is, the higher the
shareholding ratio of ETFs, the higher stock liquidity. (2) The positive change
of ETFs shareholding ratio will significantly increase the liquidity of the
underlying listed companies' stocks.
