The Influence of Foreign Direct Investment on China's High-tech Industry Innovation——A Mediation Effect Model

Based on the panel data of China's provinces from year 2009 to 2018, the internal R&D cost is introduced as an mediation variable, and the Bootstrap method is used to study the impact of foreign direct investment on China's high-tech industry innovation through the mediation effect model.

At the same time, R&D internal expenses play a significant mediation role in the impact of foreign direct investment on China's high-tech industry innovation.
