Summary
Low-carbon pilot construction effectively improves urban land green use efficiency (ULGUE) by enhancing fund allocation, talent gathering, and industrialization. This policy also drives ULGUE improvements in neighboring regions through spatial spillover effects.
Area of Science:
- Environmental Science
- Urban Planning
- Economics
Background:
- Improving urban land green use efficiency (ULGUE) is crucial for sustainable development, offering social, economic, and ecological benefits.
- China's rapid urbanization necessitates strategies to enhance ULGUE and mitigate environmental impact.
Purpose of the Study:
- To investigate the impact of low-carbon pilot city construction on ULGUE in China.
- To analyze the spatial spillover effects of low-carbon policies on ULGUE.
Main Methods:
- Utilizing a multi-period difference-in-differences (DID) method with a quasi-natural experiment design.
- Employing the spatial Dubin difference model (SDM-DID) to assess spatial correlations and spillover effects.
- Conducting robustness, parallel trend, and endogenous tests to validate findings.
Main Results:
- ULGUE in China generally increased from 2006 to 2019, with spatial concentration in eastern regions like Beijing-Tianjin-Hebei and the Pearl River Delta.
- Low-carbon pilot construction significantly and positively impacts local ULGUE through improved fund allocation, talent attraction, and industrial development.
- A significant positive spatial correlation in national ULGUE was observed, with the low-carbon policy demonstrating positive spatial spillover effects on adjacent areas.
Conclusions:
- Low-carbon pilot policies are effective in enhancing urban land green use efficiency, both directly and indirectly.
- The policy's success highlights the importance of considering regional resource and environmental conditions.
- Strengthening inter-city linkages for green production factors is vital for promoting China's overall green development and improving ULGUE.

Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley.

01:14The Carbon Cycle
39.2K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

24.6K
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.

01:01Production Efficiency
17.0K
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).
