With the contraction of the global economy and the multiple impacts of the epidemic on the world economy, Chinese enterprises are facing a changing international environment and adapting to a different kind of globalization. China insists on the strategy of both "Bringing in" and "Going abroad", and seeks the road of Internationalization through high-level two-way investment and efficient use of global resources and market space. On the topic of Internationalization of Chinese enterprises, many scholars have conducted many fruitful researches and accumulated many research results. This paper searches and collates relevant literature at national and abroad, and constructs a theoretical model of Chinese enterprises' internationalization , that includes three dimensions: influencing factors, entry modes and influencing effects. By reading the relevant literature in these three areas, we find some results, firstly the process of internationalization of firms is influenced by both internal and external factors; internal factors include the diversity of the executive team and the need for firms to innovate, and external factors include government subsidies, the active promotion of global production networks, the passive promotion of industry-specific needs and the need to expand markets. The second internationalization path includes the export access model, the contract access model, and the investment access model. Thirdly the impact effects of firm internationalization include the level of business growth, the level of research and development innovation and the level of dynamic capacity building.
