“…Secondly, focusing on the geographical location of industry–university–research subjects, it is shown that the objective geographical environment, including factors such as geographical proximity, geographical distance, and geographical concentration of industry–university–research subjects, affects the innovation performance of industry–university–research ( Wang and Luan, 2019 ; Zhang and Shen, 2019 ; Zhang and Chen, 2022 ). Thirdly, focusing on the characteristics of the industry–university–research cooperative subjects themselves, it is indicated that the resource environment, including diversity, heterogeneity, matching, and complementarity of industry–university–research subjects, affects the innovation performance of industry–university–research ( Li and Zhu, 2019 ; Zhang et al, 2021 ; Yang et al, 2022 ). Fourth, focusing on the external environment of industry–university–research, it is shown how factors such as the business environment, institutional development stage, market competition, financing environment, and government subsidies affect the innovation performance of industry–university–research ( Zhang et al, 2019 , 2021 , 2022 ; Song et al, 2022 ).…”
