Figure 3.
The image presents a line graph showing inter-regional Gini coefficients between 2011 and 2021. The horizontal axis marks years from 2011 to 2021, and the vertical axis ranges from 0 to 0.350 in increments of 0.050. Three data series are shown: Eastern-Central with diamond markers, Eastern-West with square markers, and Central-Western with triangular markers. Each series follows a distinct trajectory, showing fluctuations and differences in the coefficient values over time. The legend in the upper right links marker types to their respective region pairs, aiding interpretation of the plotted trends.The evolution trend of the inter-regional Gini coefficient of the level of foreign R&D activity in China
