政府行政成本提升政府绩效的门槛效应研究——基于2010—2015年省级政府面板数据的实证分析
Research on Government Administration Cost Promoting Government Performance Based on Threshold Effect--An Empirical Analysis of Provincial Governments Panel Data Based on 2010-2015

选取2010-2015年我国31个省、市、自治区为样本，利用门槛效应面板模型研究政府行政成本对政府绩效的非线性影响。实证结果显示：政府行政成本过低会制约政府绩效的提升，当处于5.869～6.478的合理区间时，行政成本与政府绩效间呈正相关关系，随着政府行政成本的增加，政府绩效会上升。而当超过第二门槛值6.478时，政府行政成本与政府绩效间存在显著的负相关关系，且随着行政成本扩大至第三门槛值7.021时，行政成本对政府绩效提升的负向作用达到最大。
Based on panel data from 2010 to 2015 of 31 provinces in China，this paper aims to research the nonlinear relationship between governments administrative costs and governments performance using the threshold panel data model.The research results show that：low cost of government administration will restrict the improvement of government performance；when in the reasonable range of 5.869-6.478，administrative costs and government performance are positively related，with the increase of the cost of government administration，government performance will rise；and when it exceeds 6.865，the second threshold value，there is a significant negative correlation between the governments administrative costs and performance，that is，with the expansion of administrative expenses，the government performance becomes lower；when it exceeds 7.021，the third threshold value，there is a significant negative correlation between government administration cost and performance.
