【摘要】 随着政府支出占GDP的比重不断增大,政府对长期经济增长有着越来越重要的影响。与政府支出总量相比,政府支出结构具有更重要的一面。因为政府可以在不改变其支出规模的情况下,通过优化支出结构来提高经济增长率。作者试图从理论和实证两个方面研究政府支出结构对长期经济增长的影响。本文首先综述了政府支出与经济增长关系的相关文献。以往的研究对两者之间的关系没有一个统一的看法。然后,文章建立了包含政府支出的单部门和两部门内生增长模型,从不同角度分析了政府支出结构对长期经济增长的影响。结论是,各类政府支出对长期经济增长的影响都呈现“拉弗曲线”形态:典型家庭消费跨时替代弹性的大小会影响各类政府支出的效应。接着,文章利用向量自回归模型,分析了中国1952—2006年间政府支出结构对长期经济增长的影响。研究表明,中国政府支出结构不合理,经济建设支出和行政费用所占比重过大,而社会文教和国防支出不足,这些都降低了经济效率。最后根据实证分析结果提出了如何优化政府支出结构的政策建议。更多还原

【Abstract】 With the increasing ratio of government expenditure to GDP, government plays a more important role in keeping long-run economic growth. Compared with the size of government expenditure, the composition of government expenditure is more essential. Because we can improve economic growth by optimizing the composition of government expenditure, under the condition of maintaining the scale of government expenditure. The author tries to analyze the relationship between the composition of government expenditure and long-run economic growth from both theoretical and empirical aspects.First, this paper summarizes the literature about the relationship between government expenditure and economic growth, which does not give a definite perspective. Second, this article analyzes the mechanics of the composition of government expenditure on long-run economic growth by setting one-sector and two-sector endogenous growth model containing government expenditure. The theoretical analysis suggests that the effects of various government expenditure on long-run economic growth presents as "Laffer curve", and also depends on the size of representative family’s intertemporal substitution elasticity of consumption. Thirdly, this thesis uses VAR approach to analyze the effects of the composition of government on long-run economic growth based on annual data for the period from 1952-2006 in china. The empirical research suggests that the composition of government expenditure of China is not reasonable. The excessive proportion of economic construction and administrative expense and the insufficiency of social, cultural and educational development and national defense will reduce the efficiency of economy. Finally, according to the empirical research, this paper gives some policy suggestions on how to adjust the composition of government expenditure.更多还原
