中文摘要：

当前的长三角区域环境治理尽管取得了一定成效，但其治理成本过高且难以达到持久改善的效果。长三角环境污染的根源在于投资驱动型增长导致的结构性污染锁定，以及低端经济导致的能源升级障碍。因此，环境治理应着眼于区域增长方式转型和环境与发展关系的优化，关键问题在于如何改变经济增长的推动方式与路径依赖，如何在新常态经济格局下寻求新的经济增长点，以及如何协调好不同行政区划之间的利益冲突。当前长三角区域需建立区域一体化的环境协同治理机制，推进能源升级与产业去重化进程，促进地区间错位发展与联动发展，以新型城镇化调动新的增长潜力，结合智慧城市建设转变公共服务供给方式，优化城市布局。

英文摘要：

The regional environmental governance of Yangtze River delta has obtained certain achievements, but the cost of governance is too high, and it＇ s very difficult to achieve lasting improvement effect. The root causes of pollution are the investment-driven economic growth that leads to structural pollution locking, and the low-end economy that brings the barriers of energy upgrade.Environmental governance should focus on the transformation of regional growth mode and the optimization of relationship between environment and development, so the key is how to change the way of promoting economic growth, how to seek new economic growth points under the new normal economic pattern, and how to coordinate the interest conflicts between districts. We should establish cooperative environmental governance mechanism ofthe Yangtze river delta, accelerate the process of energy upgrade and reduce the heavy chemical industry, promote the dislocation and linkage development between regions, create the new growth potential by new pattern urbanization, transformate the supplymode of public service and optimize the city layout combined with the Smart City construction.
