<p><strong>Abstract.</strong> The Defense Meteorological Satellite Program's Operational Linescan System (DMSP-OLS) night-time light imagery has been proved to be a powerful tool to monitor economic development with its relatively high spatial resolution at large scales. Night-time lights caused by human activities derived from DMSP-OLS satellite imagery are widely used in socioeconomic parameter estimations and urbanization monitoring. In this paper, DMSP-OLS night-time stable light data from

Furthermore, <i>R<sub>GDP</sub></i> was compared with statistical data of the tertiary industry structure for 28 provincial regions. The results show that the provincial <i>R<sub>GDP</sub></i> decreased abruptly in 2001&amp;ndash;2002, 2008&amp;ndash;2009 and 2011&amp;ndash;2012, which is consistent with the proportional growth of the tertiary industry in GDP. These results indicate that the changes in <i>R<sub>GDP</sub></i> can reflect tertiary industry structural changes in China's province-level regions.</p>
