中文摘要：

使用中国2000—2011年县域数据和双重差分（DID）方法评估省直管县政策对农民收入的影响,研究结果显示：在全国范围内,省直管县政策对被直管县的农民收入增长效果不佳。该政策对高收入地区有显著正向影响,在低收入地区效果不明显。省直接管理县级财政直接增加了农民收入,而经济管理权限下放没有明显作用。此外,改革前财政分权程度低的县以及农业大县显著受益于省直管县政策。分组对政策进行动态评价得出,高收入组农民收入因实施省直管县政策提高,中等偏高收入组与中等收入组收入并没有得到显著增长,该政策对低收入组的增长效应不明显。未来进一步推行省直管县政策须加强对经济发展水平相对落后地区和农业大县的试点工作。

英文摘要：

Based on a unique panel dataset of counties for the period 2000--2011, the paper analyzes the effects of reform of county directly administrated by province on farmers＇ income by difference-in-difference （DID） method.This paper concludes that the impact of this reform on the farmers＇ income growth is not good.The impact is large in high income areas and relatively small in low income areas.The fiscal system reform directly increases farmers＇ income, while the economic management delegation has no apparent effect.In addition, county with low degree of fiscal decentralization and agricultural counties benefit a lot from this policy. To evaluate the dynamic policy,we found that high income group was made to improve income. There is no significant growth in medium high income and middle income groups, and the effect is not obvious on the low income group.Therefore, the government should strengthen the implementation of these policies to poor areas and large agricultural counties.
