Abstract: This paper calculated ecological footprint of Jiangsu province between 2005 and 2015. An ecological footprint decomposition model was built based on logarithmic mean divisia index (LMDI) method. The influences of land structure, technology, economy and population on ecological footprint changes were analyzed. Additionally, the differences among the main factors influencing the ecological footprint in Jiangsu province were calculated using the Gini Coefficient, Logarithmic Mean Deviation and Theil Index. The results showed that the ecological footprint in Jiangsu increased from 2.82 ha per capita in 2005 to 3.88 ha per capita in 2015 with an annual increase rate of 3.24%. Changes in land structure, rapid economic development and population growth had promoted the growth of ecological footprint. The improvement of science and technology could inhibit the consumption of natural resources. Technical level and economic level were the main factors affecting the change of ecological footprint in Jiangsu province. The overall differences within Jiangsu province had been decreasing over time, while there were significant difference among Southern Jiangsu, Central Jiangsu and Northern Jiangsu in terms of technical and economic effects. Therefore, it is necessary to strengthen the coordinated development of Southern Jiangsu, Central Jiangsu and Northern Jiangsu to promote technological learning and economic complementary.
Key words：Jiangsu province; ecological footprint; impact factors; regional difference
