Resources and environment carrying capacity has great significance to the sustainable development of the region and the construction of the ecological civilization. Taking Jiangsu province as an example, this paper constructed the evaluation index system for environmental carrying capacity, used catastrophe progression method to analyze the change in resources and environment carrying capacity of Jiangsu from 2004 to 2014, and then built an obstacle indicators diagnosis model to further explore the factors that restrain the improvement of the resources and environment carrying capacity of Jiangsu. The results showed that:(1) the carrying capacity of resources and environment in Jiangsu was gradually increasing in fluctuation, with the value of carrying capacity increased from 0.829 0 in 2004 to 0.967 8 in 2014, and the level of resources and environment carrying capacity rose from weak(Ⅱ) to high(Ⅳ) level; (2) the resources and environment carrying capacity of the economic and social complex system showed a steady upward trend with the capacity level increased from 0.682 7 in 2004 to 0.993 1 in 2014, while the capacity of the resources and environment complex system showed a fluctuating upward trend as the capacity index changed from 0.687 3 to 0.936 6. The interaction between the economic social complex system and the resource environment complex system promoted the overall improvement of the carrying capacity of resources and environment in Jiangsu Province; (3) economy subsystem and resource subsystem were the main factors to restrain the improvement of the resources and environment carrying capacity, the per capita cultivated area was the most important obstacle factor. These above conclusions could provide theoretical support for promoting the sustainable development of economic and social in Jiangsu Province.
