This paper extensively reviews empirical studies that analyze the various impacts of the globalization phenomenon on corporate activities by using micro data. First, we set up a flow chart describing how globalization leads to national productivity enhancement. Secondly, we summarize the hypotheses and the methods explored in 13 lines of literature on globalization, which this flow chart maps. Thirdly, we discuss further possible avenues for micro data analysis. Finally, we provide some suggestions on statistics-related policies.Firm-level data; Globalization; Productivity.
