本文主要从环境保护公共开支之资本化程度的角度,探讨环境保护与经济增长间的关系。在环境保护方面的公共开支欲对经济增长发挥积极作用并形成诸如环境库兹涅茨曲线的后半段曲线,其决定性条件便是环保公共开支在资本化上的程度如何。通过构建基于经济增长模型的理论框架,可以发现,当环保公共开支资本化程度高于其他部门(譬如私人投资部门)水平时,环保公共开支便会有利于经济的增长,从而验证了环境库兹涅茨曲线的有关结论,即在经过顶部后,经济与环境出现同步改善的情况。反之,当环保公共开支资本化程度低于其他部门的水平时,前者会对经济增长造成不利影响,出现挤出效应,拖累经济增长。此外,本文还进一步剖析了在预算约束条件下,环保公共开支有利于经济增长的资本化条件。
This paper mainly discusses the relationship between environmental protection and economic growth from the perspective of the degree of capitalization of public expenditure on environmental protection. Public expenditures on environmental protection To play an active role in economic growth and to shape the second half of the curve such as the Environmental Kuznets Curve, the decisive condition is how much public spending on environmental protection is capitalized. By building a theoretical framework based on the economic growth model, we can see that when public expenditure on environmental protection is more capitalized than other sectors (such as the private investment sector), public spending on environmental protection will be conducive to economic growth, The relevant conclusion of the Nets curve is the simultaneous improvement of the economy and the environment after passing the top. On the contrary, when the public expenditure on environmental protection is lower than the capitalization of other sectors, the former will adversely affect economic growth, causing a crowding-out effect and dragging down economic growth. In addition, this article further analyzes the capitalization conditions that environmental public expenditure is conducive to economic growth under the budget constraint.
