摘要
在绿色高质量一体化发展的大背景下,以长三角城市群为研究对象,基于社会关系网络理论测度2005至2018年经济一体化和废气污染联防联控水平,并借助VAR模型验证两者间的长期动态关系。长三角经济一体化程度总体上稳定且缓慢增长,而废气污染联防联控程度呈现先下降后上升的波动演进态势;长三角经济一体化和废气污染联防联控之间存在着长期的均衡关系,且前者为后者的格兰杰原因,反之未然;长三角城市群废气污染联防联控水平同时受自身内部结构和经济一体化的双重影响,其对经济一体化冲击的响应由负转正;中后期经济一体化对废气污染联防联控的贡献效应显著增强,前者对后者能产生持久且积极的重要影响,经济和生态双重一体化极具现实价值。
In the context of green and high-quality integrated development,this paper,taking the Yangtze River Delta urban agglomeration as the object of study,measures the annual levels of economic integration and joint prevention and control of waste gas pollution from 2005 to 2018 based on the social relationship network theory,and verifies the long-term dynamic relationship between the two with the help of the VAR model.On the whole,the degree of economic integration in the Yangtze River Delta increased steadily and slowly,while the degree of joint prevention and control of waste gas pollution showed a fluctuating evolution trend that it first decreased and then increased.There is a long-term equilibrium between the two,and the former is the Granger cause of the latter,but not vice versa.The joint prevention and control level of waste gas pollution in the Yangtze River Delta is affected by both its internal structure and its economic integration,and its response to the impact of economic integration changes from negative to positive.The contribution effect of economic integration on the joint prevention and control of waste gas pollution is significantly enhanced in the middle and late period.The former can have a lasting and positive impact on the latter,and the dual integration of economy and ecology is of great practical value.
