长江经济带发展战略是立足于我国区域协调发展的出发点，通过实施基础设施建设、产业布局优化、生态环境保护等一批重大工程，来解决地区发展不平衡问题的新战略；而生态环境公平问题是党的十八大提出“五位一体”总体布局中生态文明建设重要战略思想的题中之意。生态补偿机制则是协调长江经济带区域内各地方生态发展权和生态资源重新配置的经济手段，是实现长江经济带生态公平的重要机制。本文通过揭示现象背后的原因，从构建跨界生态补偿机制的设计要素出发，在跨界生态补偿标准核算、市场化补偿依据和市场主体培育以及制度保障方面提出构建长江经济带跨界生态补偿机制的路径。同时，结合上海自身优势提出上海对接构建长江经济带跨界生态补偿机制的对策建议，以期形成地方经验和长三角经验推广至长江经济带。
The Yangtze River Economic Belt development strategy is a new strategy based on the regional harmonious development in our country，through the implementation of infrastructure construction，industry layout optimization，a batch of major projects，such as ecological environment protection to solve the problem of unbalanced development in various regions. And the ecological environmental fair problem is the topic of important strategic thoughts of ecological civilization construction in the “five-in-one” overall arrangements put forward from the 18th National Congress of the Communist Party of China.PES is the coordination of the regional ecological development of the Yangtze River Economic Belt Area and ecological resource reconfiguration of economic means，is to realize the ecology of the Yangtze River Economic Belt of fair mechanism. Therefore，building mechanism of cross-border PES plays a positive role in coordinating the ecological benefit between the middle and lower reaches of the Yangtze River of the ecological environment governance，natural resources development and ecological engineering construction，and planning as a whole the area of ecological environment protection on fair problems，therefore its urgency is self-evident. However，due to bigger difference in the middle and lower reaches of the Yangtze River Economy Belt of natural resources，geographical location，social economic condition，and building across the eastern，central and western PES mechanism in large area of the Yangtze River Economic Belt faces many problems. This paper reveals the reasons behind the phenomenon. From the building design elements of the，the building path of cross-border PES mechanism in Yangtze river Economic Belt is put forward from aspects on the PES standard accounting，marketing compensation basis and developing the market main body and the PES security mechanism in the Yangtze River Economic Belt. At the same time，combined with the advantages of Shanghai，the countermeasures for Shanghai docking of cross-border PES mechanism of the Yangtze River Economic Belt are put forward，so as to a local experience and the Yangtze River Delta experience are formed and popularized to the Yangtze River Economic Belt.
