Based on the following dataset, the attached graphs aim to test the potential influence of contributions' educational backbround (the highest academic degree they obtained) on the number of articles they contributed to the Chinese Economic Monthly/Journal, in relation to the length of articles (measured by the number of pages, visualized by the varying size of dots), and the range of topics they addressed (number of distinct topics, on a scale ranging from 1 to 7), all periods included (1) and per period (2). We relied on R package "ggplot2" to build the scattered plots.
