Taking the reform of personal income tax preferential policies in the Guangdong-Hong Kong-Macao Greater Bay Area in 2019 as an event impact, this paper examines the impact and mechanism of high-end talent introduction on the labor income share of enterprises with the data from listed companies in China. The findings show that the preferential policy of personal income tax has reduced the relative cost of enterprises labor factors, and significantly increased the share of labor income within the policy. The heterogeneity analysis reveals that competitive industries, non-state-owned enterprises, non-capital-incentive enterprises and and high-tech enterprises are more affected by personal income tax preferential policies. The mechanism analysis reveals that the personal income tax incentive policy has reduced the relative price of talent factors, which can not only motivate enterprises to increase their investment in human capital and facilitating the deepening of human capital, but also improve their innovative investment and increase the number of their R&D staff and skilled personnel, so as to increase their labor income share. Therefore, it is recommended to increase tax incentives for talents and promote the improvement and efficiency of personal income tax preferential policies; improve the talent introduction system and enhance the core competitiveness of enterprises; and optimize the talent training system of enterprises and increase the share of labor income.
