摘　　要：近年来,为发展生态经济、提升农业生产效率,各地竞相建设生态经济区。科学评价生态经济区的政策效果,对政策本身的完善及检验地方政府推动农业转型升级的成效具有现实意义。文章采用2004-2015年湖南省14个地级市的面板数据,利用双重差分与倾向值匹配法(DID-PSM),研究了洞庭湖生态经济区成立引致的农业经济效应。研究表明:政策促进生态经济区内人均农业产出效率提升了6.2%,政策促进效应呈现地域异质性与时间动态增长性,政策通过提升产出效率提高了农民人均纯收入和人均GDP;政策提升效应在DID-PSM核匹配下依然显著。In recent years, in order to develop ecological economy and improve agricultural production efficiency,many local governmentsare keen to construct ecological economic zone. Scientifically evaluating the effect of ecological economic zone policy can be good for the improvement of the policy itself and can examine whether the government works hard to construct ecological economic zone or not. This paper uses the year of 2004 to 2015 panel data of 14 cities of Hunan province,using the method of DID and PSM for studying how the setting up of Dongting lake ecological economic zone affect the regional agricultural output. This study found that the policy of ecological economic zone increases agricultural output per capita efficiency by 6.2%,the policy effect leads to heterogeneity and dynamic increases by time,the policy promotes the per capita net income of farmers and per capita GDP by improving agricultural output per capita efficiency. Under the DID-PSM test,the effect remains significant.
