By combing past literature and collecting panel data from 30 provinces and cities in China during the ten years from 2008 to 2017, a fixed-effects model was used to conduct an empirical analysis of the heterogeneous impact of OFDI reverse technology spillovers on different regions and different types of innovation models in China. The results show that: either from the perspective of the national overall or points region OFDI are significant reverse technological overflow effect; domestic r&d investment has a greater impact on technology innovation than OFDI, and it only has a significant impact on technological innovation in the eastern region, and has little impact on the central and western regions; in addition, the research also found that China's r&d personnel are relatively weak, the human capital structure is unreasonable, and the number of high-end researchers is insufficient, which seriously affects the absorption capacity of OFDI.
