Abstract:Based on the data of Chinese GEM?listed companies during 2009?2019, this paper examines whether the diversity of the countries where executives obtain their overseas experience will influence enterprises’ R&D investment decision. Furthermore, we analyze the impact of enterprise’s R&D intensity and ownership concentration on the relationship between the two above. The empirical results show that, based on the nationality dimension, the diversification of the overseas experience of the senior management team and the enterprise’s R&D investment are in an inverted U?shaped relationship.The diversification of the senior management team's overseas experience in a certain range is conducive to the increase of corporate R&D investment. As the R&D intensity increases, the positive and negative impacts of the executive team’s overseas experience diversification on R&D investment are strengthened. As the concentration of equity increases, the positive and negative impacts of the senior management team’s overseas experience diversification on R&D investment are weakened. It is recommended that the government continue to strengthen the formulation of policies for the introduction of high-level overseas talents, improve systems and mechanisms, and enterprises to build a reasonable and diversified senior management team structure with diversified overseas experience to form lasting competitiveness.
