摘要

Currently, the strengthening of regional Eco-efficiency research is imperative. This paper establishes the appropriate ecological efficiency evaluation index system by drawing on the research on the ecological efficiency of domestic and foreign scholars. First, evaluate the Eco-efficiency of 11 cities in Jiangxi Province by using DEA method. Then we use SE-DEA to sort the regional that ecological efficiency is equal to 1. Finally, using Malmquist dynamic index to analyze the eco efficiency of each region, and achieve the purpose that study on Evaluation of regional ecological efficiency. The research shows that in the study period, the ecological efficiency of the regional level of Jiangxi province is relatively low, there is no obvious difference between the ecological efficiency of each region, and the growth rate in a downward trend. Each city in the redundant input indexes vary greatly, mainly in four aspects, including the total water consumption, employees, investment in fixed assets and wastewater discharge. Therefore, Jiangxi province should actively change the mode of economic development, strengthen regional cooperation to improve the utilization of resources, actively guide foreign investment, increase investment in education, strengthen the management of environmental pollution, improve environmental governance capacity.
