2019年5月，中共中央政治局会议审议通过《长江三角洲区域一体化发展规划纲要》，明确了建设长三角生态绿色一体化发展示范区（以下简称“示范区”），要求打造生态友好一体化发展样板，破解生态发展矛盾，在高标准生态基础上推进高质量发展；破解行政区划阻止发展的障碍，在不打破行政区划基础上实现区域协调融合一体化发展。对照规划纲要的建设目标，当前示范区在生态环境保护方面面临诸多挑战和不足，从表象上看，仍存在环境质量达标压力较大、环境风险尚未消除、生态系统服务功能亟待提升等问题。透过表象看本质，可以说，示范区生态绿色一体化发展面临的不充分、不平衡等问题，一定程度上可归因于区域间的行政壁垒、制度藩篱和政策掣肘。为此，本文将在系统开展现状分析、问题梳理和经验借鉴的基础上，积极探索促进跨区域生态环境共保联治的制度创新路径，提出切实可行的对策建议，为推动示范区努力建设成为长三角世界级城市群的改革开放新高地、创新经济新高地、生态价值新高地、人居品质新高地提供政策参考。
In May 2019，the Political Bureau of the Central Committee of the Communist Party of China approved the “Outline of Regional Integration Development Plan for the Yangtze River Delta”，in which a Demonstration Area of Regional Integration on Ecological and Green Development for the Yangtze River Delta has been brought forward（hereinafter referred as the “Demonstration Area”），aiming at building a pilot showcase on ecologically friendly development，to promote high-quality economic development on the basis of higher ecological protection standards. At the same time，great importance will also be attached on making breakthroughs on cross-boundary cooperation，which will try to achieve more effective regional cooperation and integration while keeping the administrative boundary between different provinces and cities untouched. Comparing with the development targets listed in the Outline of Regional Integration Development Plan，the Demonstration Area still faces a few ecological and environmental protection challenges，eg. pressures on meeting environmental quality standards，alleviation of environmental risks，improvement on ecosystem service functions etc. When looking at the reasons causing these disadvantages or challenges，it’s rather clear that administrative and institutional barriers，as well as policy constrains have played certain roles. This article will discuss the above issues on the basis of reviewing current status of the ecological and environmental protection in the Demonstration Area，as well as cross-boundary cooperation，and explore feasible policy applications，to contribute to the promotion of building Yangtze River Delta city clusters into a new highland of reform and opening，innovative economy，ecological value，and high-quality human settlements.
