摘      要：Based on the theory of ecological efficiency,an empirical study on ecological efficiency and its changing path in Jiangsu Province during2005-2014 was conducted,and then the relationship between economic development and environmental pressure in the province was discussed by decoupling analysis. Finally,the main influencing factors of changes in ecological efficiency were analyzed by grey relational analysis method. The results showed that from 2005 to 2014,the resource efficiency of each indicator in Jiangsu Province fluctuated,while the environmental efficiency of most indicators increased slightly. The comprehensive resource efficiency and environmental efficiency also fluctuated,and the fluctuation range of the comprehensive environmental efficiency was larger than that of the comprehensive resource efficiency. Seen from the temporal evolution of ecological efficiency and circulation economy development pattern in Jiangsu Province,the leaping development mode was adopted in the province.The decoupling state of economic development and environmental pressure in Jiangsu Province was unstable,and they were in a state of strong decoupling,weak decoupling and expensive recoupling in most years. According to the results of grey relational analysis,comprehensive utilization of solid waste,industrial electricity consumption,electricity consumption of the whole society,domestic energy consumption,discharge of urban domestic sewage,and production of common industrial solid waste were the main influencing factors of changes in ecological efficiency in Jiangsu Province.
