Introduction
The master plan of "Shanghai 2035" proposed to make Shanghai a desirable city of innovation, humanities and ecology, with the goal of improving the vitality and quality of the city. It actively explores a progressive and sustainable organic renewal model, preserves and inherits urban culture, promotes the use of space to intensive and compact, functionally complex and low-carbon efficient. Binjiang in Shanghai has become an important area to carry the core functions of the global city in the "Shanghai 2035" urban master plan. Similar to the deindustrialization process of urban waterfronts worldwide [1] , Binjiang in Shanghai has undergone a development of functional metabolism and green renewal, with the former industrial functions being re-substituted by new functions such as entertainment, commerce and offices, the quality of the ecological environment being upgraded, and the waterfront public open space shared by citizens being full of urban vitality. In such a context, this paper establishes a comprehensive impact assessment system for the post-transformation of the riverfront industrial zone through relevant studies, standards and theories and other literature studies [2] [3] [4] , and proposes a green renewal strategy for the transformation and development of the riverfront industrial zone to provide an important supporting force for the transformation of the city's riverfront industrial belt.

The post-transformation assessment system
Binjiang in Shanghai experienced the push of the city expo, urban renewal, and in ecology, culture, industry import, functional positioning has been greatly enhanced as well as the promotion and support of the policy at the government level. The impact of policy, economy, and environment etc. needs to be assessed from the heritage protection, green transformation, ecological environment improvement, and the existing industrial zone of functional form enhancement development to carry out the comprehensive assessment of the impact after the transformation.

Assessment model
Taking the Binjiang industrial belt as the object to establish a post-transformation comprehensive impact model from three dimensions of assessment object, functional positioning and transformation [5] , we create a first-level objective of post-transformation comprehensive impact assessment covering planning and development, operation and management, cultural continuation, ecological regeneration and vitality perception around macro conditions, protection and utilization, ecological quality, personnel feeling and operation mode.

Post-assement Objectives
Based on the comprehensive impact model, a postassessment target system is established, in which the planning and development impact assessment targets focus on comprehensive economic strength, functional positioning matching degree, and policy implementation degree. The operation management influence focuses on the operation management mode, green economic benefits, and the creation of innovative demonstration projects. Cultural continuity impact focuses on historical longevity, cultural memory, iconic initiatives, increase in cultural and creative enterprises, and satisfaction with cultural full atmosphere. The impact of site regeneration focuses on the natural environment of the site, sustainable use of resources, green building ratio, plant community creation, and greening coverage ratio. Vitality perception influence focuses on public open space vitality, traffic convenience, shared intelligent facility experience, cultural activity richness, and service facility diversity.
Based on literature research, combing relevant standards and norms, questionnaire surveys and statistical analysis of big data, the post-assessment target system indicators are assigned in Table 1~Table 5.

Analysis of Binjiang Assessment
Around the vision of Shanghai to build "an excellent global city", according to the unified plan of the municipal government, according to the requirements of "hundred years plan, century fine", Binjiang in Yangpu District and Binjiang in Xuhui District and other "riverfront industrial zone "adhere to the" ecology first, function first "based on" reproducing the style and reshaping the function". They focus on the riverfront public space through the project, accelerate the planning, pay attention to the construction, connect the breakpoint, focus on reflecting the characteristics, and inherit industrial civilization. Efforts are made to build it into a public space and living shoreline that serves the public for fitness and leisure, sightseeing and tourism. Combining the development and characteristics of the two cases [6] [7] [8] [9], the comprehensive impact assessment analysis after the transformation is carried out. The assessment is as follows. According to the transformation and development of Binjiang in Shanghai and the model of post-assessment comprehensive influence, from the upgrading of industrial functions in the early stage, to the green renewal of current buildings, from the improvement of environmental quality, to the inheritance of industrial culture, the transformation and upgrading of the industrial zone of Binjiang are carried out by formulating a sustainable development strategy of green renewal.

Upgrading of industrial functions
Create a waterfront area that is suitable for business, living, fun and tourism, build an ecological industrial development system in the riverside area, and create a cultural cluster with regional characteristics along the river. Binjiang in Yangpu District is gradually developed into an innovative development belt with international influence. From "industrial rust belt" to "industrial show belt", it has transformed into a "people's city for the people" model place. Binjiang in Xuhui District is aligned with the Left Bank of Paris and the South Bank of London, and has opened a chapter of urban renewal from a production-oriented shoreline to a living-oriented shoreline, and has updated its positioning for art, sports, business, culture and technology functions, implementing the "Double A" plan for the West Bank, namely "ART" art and "AI" artificial intelligence, aiming to create a diversified industrial and cultural ecology.

Green growth of buildings
The transformation of the waterfront industrial zone brings new growth space for urban construction, and the new buildings create green and healthy class buildings, and provide green indoor space for the people living and working through the construction of high standard and high quality green building groups, while encouraging green transformation for buildings with certain historical significance that can be reused to achieve the goal of saving resources and protecting the environment for the whole life of the buildings. Take the former building of the tobacco company as an example, although the age limit of the construction and the craftsmanship don't have a conservation value, in the context of enhancing the overall landscape appearance and playing the demand of the maximum utilization of the building, the building is retained for green renewal, making it an urban riverfront complex integrating municipal infrastructure, public green space and public supporting services. It utilizes the retreat of the planned green space on the north side of the current Chinese tobacco warehouse to extend the city side, forming a gentle slope to access the city, mulching and planting on the slope to build a park, and arranging parking and other basic services under the slope so that people can stroll from the city to the riverbank unconsciously [10] .

Improvement of environmental quality
By improving soil quality, we can create a reasonable plant community, improve the quantity and quality of plants, better play its value in the ecosystem, maintain the balance of the ecosystem, and adopt an ecological restoration strategy. At the same time, the water-friendly platform and public space have changed the old environment along the river, improved the waterfront ecological environment, created a riverfront landscape and water-friendly public space, improved the overall image of the city, and realized the "returning the river to the people", and Greenland Plaza has created a sponge park landscape by practicing development with low impact.

Heritage of industrial culture
The industrial zone along the riverfront carries many cultural memories. The protection and inheritance of these historical elements with industrial cultural values is not only an important carrier for the protection of public awareness of history and culture, but also a cultural memory for the protection of public life from generation to generation. Through the protection of historical culture, historical style buildings and industrial relics along the riverfront, we inherit the spirit of sea culture and urban culture, and inject cultural connotation into the development of the Binjiang. Taking the Longhua Airport in Binjiang, Xuhui District as an example, the renovated Longhua Airport runway shows the imprint of aviation history, adopts the design concept of urban trajectory, organizes streets and parks into a unified runway system with diversified linear spaces, intersperses water systems and greenland, and sets up rain gardens in combination with the sponge city concept, transforming the former Longhua Airport runway into a runway for cars, bicycles, people and rivers, forming a beautiful urban public space integrating history and landscape.

Conclusion
Based on the transformation and development of Binjiang in Shanghai in recent years, this paper explores a progressive and sustainable organic regeneration model for the riverside industrial zone with the goal of improving the vitality and quality of the city. Through the research and analysis of "green growth and ecological renewal", we have established a comprehensive impact assessment system for the transformation of the riverfront industrial zone with three dimensions of transformation connotation, including assessment object, functional positioning and transformation. Taking Binjiang in Yangpu District and Binjiang in Xuhui District as the cases for assessment and analysis, we have proposed a green renewal development strategy for the transformation and upgrading of the Binjiang in four aspects: industrial function upgrading, green building growth, environmental quality improvement and industrial culture inheritance, and provided technical support for the transformation of the Binjiang industrial belt in the future.
