本文基于非参数的Malmquist指数和空间计量分析方法,采用中国2007—2010年的省际面板数据,首次估算了中国地方政府财政支出在减少城乡居民收入差距方面的效率,以及这一效率的空间相关性和异质性。研究发现,大部分省份财政支出在减少城乡居民收入差距方面的效率较低,地方政府的支出效率与经济发展水平不相关。另外,各地区间财政支出缩小城乡收入差距效率出现了收敛趋向,主要体现在区域经济带内部,各经济带之间的效率差异显著,中部地区效率最高且有上升的趋势,西部地区的效率最低且有下降的趋势,而东部地区则比较稳定。
Based on the non-parametric Malmquist index and spatial econometric methods, this paper uses China’s provincial panel data from 2007 to 2010 for the first time to estimate the efficiency of local government fiscal expenditure in reducing the income gap between urban and rural residents and the spatial correlation of this efficiency Sexual and heterogeneous. The study found that the fiscal expenditure in most provinces is inefficient in reducing the income gap between urban and rural residents, and the efficiency of local government expenditure is not related to the level of economic development. In addition, the efficiency of reducing the income gap between urban and rural areas tends to converge, which is mainly reflected in the regional economic zone. The efficiency of each economic zone is significantly different. The central region has the highest efficiency and the upward trend. The western region has the lowest efficiency There is a downward trend, while the eastern region is relatively stable.
