Still, it has experienced the development process of regional expansion, industrial extension and connotation enrichment. In order to strengthen the support of finical investment to the construction of Poyang Lake Eco-economical Zone, the domain of the finical expenditure for the zone should be clarified and reasonable methods should be selected. Through quantitative analysis, this paper provides the fiscal support scale for the zone. It also estimates the input-output efficiency of each local government in the zone by means of the data envelopment analysis, so as to analyze the rationality of the existing system. The result shows that in recent years the fiscal scale has increased fast and the fiscal efficiency has been improved. From the point of the entire inputs, the output efficiency of Poyang Lake Eco-economical Zone is higher than that of other non-lake areas, but the entire efficiency is decreasing year after year, so it is necessary to take measures to improve the environment output efficiency.

Key words: Poyang Lake Eco-economic Zone; fiscal expenditure; data envelopment analysis
