Figure 1
The horizontal axis represents years and has markings ranging from 1995 to 2025 in increments of 5 units. The vertical axis has markings ranging from 0.75 to 0.785 in increments of 0.005 units. The graph shows a curve that starts from (2000, 0.782), rises concave up passing through (2001, 0.781), (2004, 0.783), slopes down passing through (2007, 0.78), (2006, 0.78), (2010, 0.756), rises upward in a zigzag fashion passing through coordinates (2011, 0.756), (2013, 0.76), (2014, 0.76), (2015, 0.765), (2017, 0.765), (2018, 0.763), (2020, 0.767), (2021, 0.768), and terminates at (2022, 0.768). Note: All numerical data values are approximated.The export efficiency of Vietnam from 2000 to 2022. Source: Created by authors
