Summary
Urban green development efficiency (UGDE) in China shows a rising trend, with improvements driven by peer effects between cities of different sizes. Eastern regions lead, while western regions lag, indicating a need for balanced growth.
Area of Science:
- Environmental Science
- Urban Planning
- Regional Economics
Background:
- Global urban development faces ecological security and pollution challenges.
- Green development is crucial for urban sustainability and environmental problem mitigation.
- Understanding urban green development efficiency (UGDE) is vital for sustainable cities.
Purpose of the Study:
- To analyze the spatial-temporal evolution of urban green development efficiency (UGDE) in China.
- To investigate the peer effects of UGDE between cities of different grades.
- To provide insights for promoting green development in urban areas.
Main Methods:
- Panel data analysis of 283 prefecture-level cities in China (2003-2017).
- Spatial-temporal evolution analysis of UGDE.
- Peer effect analysis considering city size and geographical proximity.
Main Results:
- Average UGDE in China increased by 29.79% from 2003 to 2017.
- Eastern regions consistently showed higher UGDE; western regions lagged.
- The center of gravity for UGDE shifted northwest, indicating spatial dispersion.
- Positive peer effects were observed: large cities influenced medium/small cities, and medium cities influenced small cities.
Conclusions:
- UGDE in China is improving, but regional disparities persist.
- Peer effects play a significant role in UGDE improvement across different city sizes.
- Targeted policies are needed to address regional gaps and leverage peer effects for balanced urban green development.

Production Efficiency
15.7K
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).

Trophic Efficiency
19.5K
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.

Global Climate Change
24.4K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Sustainable Development
12.9K
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.

Exponential Equations for Modeling Growth
459
Exponential models are essential for describing rapid, multiplicative changes in natural systems, such as population growth. When a population doubles at regular intervals, the process can be modeled using a suitable base. For instance, a bacterial culture that doubles every three hours follows the model n(t)=n0⋅2t/3, where n(t) is the population at the time t.A more general model uses the natural base e, especially for continuous growth. This takes the form n(t)=n0⋅ert, where r is...
