政府异质型环境支出的乘数效应研究
Multiplier effects of government heterogeneous environmental expenditure
摘要
Abstract
Environmental expenditure serves as a crucial instrument for governments to protect the ecological environment and pro-mote stable and sound economic growth.Against the backdrop of increasingly severe environmental problem,scientifically evaluating the effectiveness of government environmental expenditure is of great academic value and practical significance for optimizing its struc-ture and maximizing its role in pollution control.This study developed a medium-scale environmental dynamic stochastic general equi-librium(DSGE)model incorporating heterogeneous environmental expenditure policies.By using this model,the study systematically examined the differentiated effects of environmental governance expenditure and emission-reduction subsidy expenditure on the macro-economy and environment,and quantified their respective environmental fiscal multipliers.The study found that:① Both environmen-tal governance expenditure and emission-reduction subsidy expenditure could reduce regional carbon emissions and promote economic output,but the former was less effective in stimulating enterprises'voluntary emission-reduction incentives than the latter.② Further analysis showed that the multiplier effects of both types of expenditure on the economic-output declined over time,whereas their multi-plier effects on emission-control increased gradually.③ In the short run,environmental governance expenditure recorded larger multi-plier effects on both economic output and emission control than emission-reduction subsidy expenditure,whereas the opposite held true in the long run,indicating that the long-term impact of emission-reduction subsidy expenditure was more pronounced.④ Environmen-tal regulation significantly affected the multipliers of government environmental expenditure:after introducing environmental regulatory policies,the multiplier effects of both environmental governance expenditure and emission-reduction subsidy expenditure on economic-output declined markedly,while their multiplier effects on emission-control increased substantially.Based on these results,China should maintain proactive environmental fiscal policies to address ecological challenges and sustain economic development.At the same time,the composition of environmental fiscal expenditure should be optimized in a timely manner to give full play to the incentive effects of environmental fiscal policies,thereby guiding and strengthening enterprises'independent innovation.关键词
