行政腐败的宏观经济学分析

本文在增长模型中引入行政腐败和由行政腐败而引起的调整成本 ,考察其对经济增长的影响。通过模型分析得出 ,当政府公共支出的边际生产率比较高 ,税率比较低以及由腐败引致的调整成本比较高时 ,行政腐败对经济增长的负面影响占主导地位。通过对我国行政腐败与公共支出、经济增长率之间关系进行实证分析得出 :在我国市场化过程中 ,行政腐败降低了我国经济增长率 ;在我国公共支出领域 ,行政腐败行为的发生浪费了大量的公共支出。不论以受贿金额占GDP的比重 ,还是以腐败涉及县处以上官员的变动作为衡量行政腐败的指标 ,行政腐败与公共支出占GDP的比重都呈现正相关关系 ;在我国经济发展的过程中 ,存在着大量的预算外支出。预算外支出为腐败行为的发生提供了便利。而且 ,预算外支出由地方或政府官员控制 ,由此引起围绕公共支出的调整成本上升。这表明 ,预算外支出就整体而言阻碍了经济增长。

The Macroeconomic Analysis of Administration's Corruption

This paper analyzes the influence of administration's corruption and the adjustment cost which is caused by administration's corruption. Through the model's analysis we get the conclusion that when the marginal production efficiency of public expenditure is high and the tax rate is low, the administration's corruption's negative influence towards economic growth will predominate. Through positive analysis we get the following conclusions. Firstly, administration's corruption decreases economy growth rate. Secondly, administration's corruption wastes lots of public total expenditure.The relation between administration's corruption and public expenditure is positive. Thirdly, in the process of economic development of our country,there exists a large quantity of the outbudget's expenditure. What's more, outbudget's expenditure is controlled by local government or local government's civil servants. Therefore, the adjustment cost of public expenditure increases. This demonstrates that outbudget's expenditure hindered economic growth in the whole.
