Summary
Most Chinese cities show moderate coupling between urbanization and eco-efficiency. While Southern regions lead, disparities are decreasing, indicating progress in synchronized sustainable urban development.
Area of Science:
- Urban and Regional Planning
- Environmental Science
- Sustainable Development
Background:
- Urbanization and eco-efficiency are crucial for sustainable urban development but their synchronized progress is understudied.
- Understanding the interplay between urbanization process (UP) and eco-efficiency (EE) is vital for effective policy-making.
Purpose of the Study:
- To analyze the spatial and temporal dynamics of the synchronized development between urbanization and eco-efficiency in 255 Chinese cities.
- To identify regional disparities and spatial autocorrelation in the coupling coordination between UP and EE.
Main Methods:
- Entropy method for data processing.
- Super-efficiency SBM (Slъкp-based Measure) model for eco-efficiency assessment.
- Coupling coordination degree model to evaluate the synchronized development between urbanization and eco-efficiency (CC-UE).
Main Results:
- Approximately 97% of surveyed cities exhibit a moderate level of coupling coordination between urbanization and eco-efficiency.
- Significant spatial disparities in CC-UE performance were observed, with Southern and Southeastern China performing better, though these differences are diminishing.
- Analysis revealed evident spatial autocorrelation in the CC-UE performance across the studied cities.
Conclusions:
- The findings highlight a generally moderate but improving synchronization between urbanization and eco-efficiency in China.
- Policy interventions should consider regional specificities to further enhance coordinated sustainable urban development.
- The study provides a framework for assessing synchronized urban and environmental development globally.

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground...

01:01Production Efficiency
16.9K
Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).

00:46Trophic Efficiency
20.7K
Trophic level transfer efficiency (TLTE) is a measure of the total energy transfer from one trophic level to the next. Due to extensive energy loss as metabolic heat, an average of only 10% of the original energy obtained is passed on to the next level. This pattern of energy loss severely limits the possible number of trophic levels in a food chain.

GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...
