【 摘 要 】

As one of the most developed regions in China, the Yangtze River Delta (YRD) is experiencing rapid industrialization and urbanization, which is accompanied by huge energy consumption and CO2 emissions. Moreover, Chinese government has recently redefined the scope of YRD to include 8 cities in Anhui province. In this case, it is crucial to evaluate new-YRD's sustainability by studying industrial energy efficiency (IEE) with CO2 emissions at city level. To this end, we evaluate IEE of 26 cities in YRD and its space-time distribution during 2006-2015 based on Shephard energy distance function and GIS visualization method, respectively. The findings reveal that IEE in YRD shows an ascending trend during the study period. Moreover, the saptial distribution of the IEE presents the characteristics of low in south, high in north, indicating the existence of a spatial cluster. Finally, a couple of suggestions are concluded.
