生产性公共支出、空间溢出效应与区域经济差距——基于多地区动态一般均衡模型的分析
Productive public expenditure, spatial spillover effect and regional economic disparities: based on multi-regional DGE model
摘要
Abstract
The regional economic disparities among eastern, central and western China have been constantly increasing since China's reform and opening-up.To coordinate the development of regional economy, the government is gradually inclining productive public expenditure to central China and western China which are less developed.In order to evaluate this fiscal policy comprehensively, based on traditional DGE analysis we propose a macroeconomic analytical framework with productive public expenditure and its spatial spillover, and establish a multi-regional DGE model to simulate the impacts of current regional productive public expenditure policy and its adjustments on regional and national economies.Several conclusions can be derived according to the simulation results: ①on the base of current spatial distribution of productive public expenditure, distributing the additional productive public expenditure across all regions receives inconspicuous results for regional coordinated development;②concentrating additional productive public expenditure in less developed regions can reduce regional economic disparities while not maximize national output per capita because of the low marginal productivity of infrastructure and the weak spatial spillover effect;③concentrating additional productive public expenditure in more developed regions can increase regional economic disparities while maximizing national output per capita because of the high marginal productivity of infrastructure and the strong spillover effect.Two policy implications can be obtained from the research: given the current pattern of regional distribution, the inclination of the additional productive public expenditure to less developed regions, which can stimulate the increase of their local outputs directly, is regarded as a suboptimal fiscal policy with the objective of reducing regional economic disparities.According to efficiency criteria, the optimal target regions of productive public expenditure should be the more developed regions because of their high marginal productivity of infrastructure and strong spatial spillover effect.关键词
