'省直管县'对县级政府运行成本的影响:基于双重差分模型的实证研究

摘要

控制地方政府运行成本是我国新时期行政体制改革的一个重要主题,而"省直管县"改革政策旨在降低政府运行成本.围绕"省直管县"是否以及如何对县级政府运行成本产生影响的研究问题,本研究的理论框架是:控制经济增长﹑城市化水平﹑财政能力﹑地域范围和政府规模之后,"省直管县"改革政策通过改变资源﹑权力和行政流程来降低县级政府运行成本.通过以湖北和江苏1999年至2006年数据为自然实验的样本进行双重差分模型检验,发现"省直管县"改革政策显著减少了县级政府的运行成本.%In new period,controlling local governmental operation cost is a major problem of the ad-ministrative system reform,and the"province governing county"reform policy aims to reduce governmental operation cost.The research question is how"province governing county"impacts on county-level gov-ernmental operation cost.The theoretical framework of this study is:without the interruption of controlling economic growth,urbanization level,fiscal capacity,span of control and government size,the"province governing county"reform policy influences county-level governmental operation cost and provincial gov-ernmental operation cost,by changing resources,power and process.This research conducts empirical a-nalysis by using data from 1999 to 2006 in Hubei Province and Jiangsu Province.It sets"difference in difference model(DID)",and finds that:the"province governing county"reform policy significantly re-duces the county-level governmental operation cost.
