收入不平等、经济增长与财政支出偏向

Income Inequality,Economic Growth and Fiscal Expenditure Bias

在存在财政支出偏向的视角下考察收入不平等与中国经济增长之间的关系。首先通过建立数理模型,从理论上说明收入不平等、经济增长与财政支出偏向三者之间的关系。随后,通过建立面板计量模型进行经验研究,检验理论模型的结论。研究结果表明:其一,当政府存在财政支出偏向时,收入不平等对中国的经济增长有正向效应;其二,财政支出增加总体上有利于中国经济增长,但不利于收入不平等程度的缩小。收入不平等程度过高是内需不足的一个重要原因,治理中国经济结构失衡要求调整政府的财政支出结构,适当减少生产性公共品的供给,增加公共福利性支出,扭转政府在财政支出方面的城市偏向政策。

The perspective of the presence of fiscal expenditure biased, the paper re - examines the relationship between income inequality and economic growth in China. By establishing a mathematical model theoretically, we first explain income inequality, economic growth and fiscal expenditure bias the relationship between the three. Subsequently, through the establishment of the panel econometric model, we test the conclusions of the theoretical model. Results of the study showed that： （1） When the government expenditure bias exists, the income inequality has a positive effect on the China＇s economic growth; （2） The increase of the fiscal expenditure is generally benefi- cial to the China＇s economic growth, but it is not conducive to the reduction of the degree of income inequality. High degree of the income inequality is an important reason of insufficient domestic demand. The governance of the imbalance of China＇s economic structure requires government to adjust the fiscal expenditure structure, appropriate to reduce the supply of productive public goods, increasing the public welfare spending, and reversing the urban bi- ased policies in the government fiscal expenditure.
