中文摘要:

      科学监测环境规制强度并识别其障碍因子，是提升区域环境韧性、促进社会—经济—环境协同可持续发展的重要路径。本文基于政府主导、市场激励与公众参与三维框架，构建环境规制强度指标体系，采用CRITIC（Criteria Importance Through Intercriteria Correlation）-熵权组合法对长江经济带各省市2012—2022年环境规制强度进行测度，系统解析其时空分异特征与障碍因子。研究发现：①研究期环境规制强度总体呈现出波动上升趋势，从0.359增加到0.468，年均增速2.19%，区域协同发展效应显著。②空间分异上，下游地区>中游地区>上游地区，均值分别为0.515、0.447及0.401。中游地区增速最快（3.64%），而上游地区在均值（0.401）与增速（2.87%）上均显滞后。③全局莫兰指数反映出空间集聚特征持续强化，空间联动性显著提升。局部空间格局表现为“高—高”型集聚或“低—低”型集聚，且“高—高”型集聚的省市逐渐增多。④政府主导、市场激励与公众参与的障碍度平均值分别为43.45%、34.67%、21.89%。最后本文针对以上结果提出了相关政策建议。

英文摘要:

      Scientific monitoring of environmental regulation intensity and identification of its obstacle factors are critical pathways to enhance regional environmental resilience and promote the coordinated sustainable development of society, economy and environment. This study constructed an environmental regulation intensity index system based on a tripartite framework encompassing governmentled initiatives, market incentives and public participation. Employing the CRITIC-entropy weight combination method, we measured the environmental regulation intensity across provinces in the Yangtze River Economic Belt from 2012 to 2022, systematically analyzing its spatiotemporal differentiation characteristics and obstacle factors. The findings revealed that:①Environmental regulation intensity during the study period exhibited a fluctuating upward trend, increasing from 0.359 to 0.468, with an average annual growth rate of 2.19%, demonstrating significant regional synergistic effects.② In term of spatial heterogeneity, the intensity ranked as follows: downstream > midstream > upstream gradient, with mean values of 0.515, 0.447, and 0.401, respectively. The midstream regions demonstrated the fastest growth rate (3.64%), while the upstream regions lagged behind in both mean value (0.401) and growth rate (2.87%).③ The Global Moran’s Index indicated a continuous strengthening of spatial agglomeration and a significant enhancement in spatial connectivity, with local spatial patterns dominated by“high-high” and“low-low” clusters, where“high-high” clusters expanded progressively. ④The average constraint intensities of government-led measures, market incentives, and public participation were 43.45%, 34.67%, and 21.89%, respectively. Targeted policy recommendations were proposed to address these findings.
