A total of 136 institutional innovation achievements have been formed, of which 38 are being replicated and promoted nationwide; Continuously promoting the construction of 145 key projects and driving high-quality regional development... 2023 marks the fifth anniversary of the Yangtze River Delta integration development becoming a national strategy. As the "first move" and "breakthrough" of the national strategy for the integration of the Yangtze River Delta, the Yangtze River Delta Ecological Green Integration Development Demonstration Zone, which spans Shanghai, Jiangsu, and Zhejiang, has been listed for four years. It has shown a new look of high-quality integrated development from the weak areas at the provincial border in the past, and the demonstration effect of "implementing a small area, coordinating a large area, and leading a whole area" has been continuously strengthened. The dual wheel drive of institutional innovation and project construction crosses the Taipu River in Shanghai, Jiangsu, and Zhejiang. The iconic building at the junction of two provinces and one city, Fangting Water Institute, is currently under construction. Looking down from the air, Fangting Water Academy happens to be located at the "origin" of the border between Shanghai, Jiangsu, and Zhejiang. The project adopts a quadrangle design, with four themed exhibition spaces set up at the four corners, namely Shanghai, Jiangsu, Zhejiang, and Anhui. In the view of Liu Qunxing, Deputy Minister of the Ecological Planning and Construction Department of the Executive Committee of the Yangtze River Delta Integration Demonstration Zone, the planning and construction of Fangting Water Institute is a combination of top-level design and grassroots exploration. "Although the project spans three regions, in the specific promotion process, integrated approval has been achieved. The construction unit only needs to prepare a set of materials, run to one department, and stamp a seal." Beside Sanbaidang in Wujiang, Jiangsu, there were only a few exhibition boards and one construction site last year, Nowadays, the Hengli (Yangtze River Delta) International New Materials Industry Base has been established, and the first phase of the production line has been put into operation. After the base is fully operational, it is expected to achieve an annual sales revenue of 20 billion yuan. "From nail polish in daily chemicals to protective film behind photovoltaic power generation panels, polyester film is widely used." Ju Jinhu, the relevant person in charge of Hengli (Yangtze River Delta) International New Material Industry Base, said that in the future, the base will continue to develop a number of world-class technologies and products in the field of new material industry. Gu Jun, Secretary General and Director of the Executive Committee of the Yangtze River Delta Integration Demonstration Zone Council, introduced that adhering to the dual drive of institutional innovation and project construction, the demonstration zone has accumulated 136 institutional innovation achievements in the past four years, of which 38 are being replicated and promoted nationwide; A total of 145 key projects have been promoted, and substantial development has been initiated in the key areas of "one hall, three areas"; The developer alliance of the demonstration zone has gathered 64 entities to empower the construction of the demonstration zone. The data shows that in the past four years, the demonstration zone has promoted 20 key ecological and environmental protection projects, with the aim of improving quantity and quality and creating a model room for green development. From 2019 to 2022, the proportion of Class III surface water sections in the demonstration zone increased from 75% to 96.2%, and the excellent air quality index rate increased from 78.4% to 83.3%. The water environment quality of key cross-border water bodies has reached or exceeded the 2025 target ahead of schedule. The excellent ecological environment provides strong support for economic transformation, and the green development of the demonstration zone has achieved remarkable results in the past four years. In Jinze Town, Qingpu, Shanghai, a series of rivers and lakes form a "blue pearl chain". The excellent ecology has attracted the settlement of Huawei Qingpu R&D Center, with 8 clusters and over 100 buildings in the park capped and under renovation. Huawei Qingpu R&D Center has a total investment of over 10 billion yuan and is expected to be completed and delivered in 2024. After delivery, the park can accommodate approximately
