摘要
环境规制是实现经济—资源—环境(ERE)系统协调发展的重要政策工具。以ERE属性特殊的中国53个海岸带城市为研究对象,系统测算2003—2020年ERE耦合协调度,运用固定效应和中介效应模型探究不同环境规制工具对海岸带城市ERE耦合协调度的影响机制。研究发现:(1)2003—2020年ERE耦合协调度呈增长态势,但整体仍处于中低水平,区域非均衡状态减弱;(2)命令型环境规制对ERE耦合协调度存在倒“U”型影响,市场型环境规制对其存在“U”型影响,多数城市处于命令型环境规制促进和市场型环境规制抑制阶段;(3)技术创新在环境规制工具对ERE耦合协调影响中发挥部分中介效应,而产业结构升级在命令型环境规制影响中存在部分中介效应,在市场型环境规制影响中存在遮掩效应。
Environmental regulation is an essential policy instrument for achieving coordinated development of the economy-resources-environment(ERE)system.Taking 53 coastal cities in China where the ERE system has more distinct properties and more obvious contradictions between subsystems as the research object,this paper systematically calculates the ERE coupling coordination from 2003 to 2020 by using entropy weight method.Then,this paper aims to explore the impact and mechanism of different environmental regulation tools on the coupling coordination degree of ERE system of coastal cities by utilizing the fixed effect model and mediation effect model.The results indicate that:(1)The coupling coordination degree of ERE system increased from 2003 to 2020,but its overall level is still at a medium to low level.And the regional imbalance of the coupling coordination degree of the ERE system shows a weakening trend,and the gap between cities was gradually narrowed over time.(2)The coupling coordination degree of ERE system is impacted in an inverted"U-shape"by command-oriented environmental regulation,whereas market-oriented environmental regulation has a"U-shaped"impact on the coupling coordination degree of ERE system.It is found that that the coupling coordination degree of the ERE system in most cities is promoted by command-oriented environmental regulation and inhibited by market-oriented environmental regulation according to the inflection point position.(3)Technological innovation contributes to the partial mediation effect in the influence of environmental regulation tools on the coordinated development of ERE system.Different from technological innovation,the upgrading of industrial structure has partial mediation effect in the influence of command-oriented environmental regulation on the coordinated development of ERE,while it has masking effect in the impact of marketoriented environmental regulation on the coordinated development of ERE system.
