JUPD_Data.zip

English
This package contains the natural-city shapefile used with NPP-VIIRS nighttime-light observations to identify shrinking cities in China. The related study evaluated 2,862 natural cities during 2013-2016 and identified 798 shrinking cities. The archive was reconstructed from the verified BCL local research folder because the historical .com download binary is no longer available; the historical archive filename is retained for continuity.
