Time change of EWP. This set of spatial variation maps (a–f) presents the EWP change rates of CCUA cities at five two-year intervals (2012–2014, 2014–2016, 2016–2018, 2018–2020, 2020–2022) and the average annual change rate (2012–2022). The figure uses a color gradient to represent change rate magnitudes (positive values for growth, negative values for decline).
