Are We Satisfied with the Achievements of New Eco-City Construction in China? A Case Study of the Sino-Singapore Tianjin Eco-City

With the goal of sustainable urbanization, eco-cities have garnered significant global attention in recent decades. Unlike eco-city renovation or renewal, the construction of a new eco-city represents a comprehensive urbanization process that integrates environmental sustainability with livability. To evaluate the outcomes of new eco-city construction in China, this study employs a dual approach combining objective achievements and residents’ subjective satisfaction to systematically examine the Sino-Singapore Tianjin Eco-City. The analysis encompasses five dimensions: environmental amenity, life safety, residential functionality, traffic capability, and economic well-being, with the relative weights of specific indicators determined through the entropy method, expert scoring, and analytic hierarchy process. The findings reveal that based on objective indicators, the eco-city’s overall performance nearly doubled during its first phase of development, with life safety showing the most notable improvements. However, subjective assessments revealed that overall resident satisfaction remained below 70%, with residential functionality receiving the highest rating. The annual progress of the eco-city did not consistently align with residents’ needs, and no clear correlation was found between the eco-city’s current state and public sentiment. For sustainable development, the eco-city must address its shortcomings and better cater to residents’ demands across various dimensions through targeted and effective strategies.
