Summary
The country-level garden city image (CGCI) program boosts urban eco-efficiency by increasing green coverage and attracting talent. However, its positive impacts are mainly observed in western regions, not eastern developed cities.
Area of Science:
- Environmental Science
- Urban Planning
- Economics
Background:
- Eco-efficiency is crucial for sustainable urban development.
- A city's environmental image may influence its eco-efficiency.
- The country-level garden city image (CGCI) program aims to improve urban environments.
Purpose of the Study:
- To investigate the causal effect of the CGCI program on urban eco-efficiency.
- To analyze how the CGCI program impacts urban green coverage, industrial structure, and talent attraction.
- To examine the heterogeneous effects of the CGCI program across different regions in China.
Main Methods:
- Utilized a dataset of Chinese prefecture-level cities from 2005 to 2016.
- Employed propensity score matching combined with the difference-in-differences method for causal inference.
- Analyzed the program's impact on urban green coverage, industrial structure, and talent attraction.
Main Results:
- The CGCI program significantly enhances urban eco-efficiency.
- Key mechanisms include expanded urban green coverage, optimized industrial structure, and attraction of talented inhabitants.
- CGCI certification effects are heterogeneous, showing positive impacts in western regions but insignificant effects in eastern developed cities.
Conclusions:
- The CGCI program is an effective policy for improving urban eco-efficiency.
- Regional disparities exist in the effectiveness of the CGCI program.
- The findings suggest targeted implementation strategies for maximizing the program's benefits.

17.3K
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).

01:16Efficiency of The Carnot Cycle
3.1K
The hypothetical Carnot cycle consists of an ideal gas subjected to two isothermal and two adiabatic processes. Since the internal energy of an ideal gas depends only on its temperature, which is the same before and after the completion of the Carnot cycle, there is no change in its internal energy. Hence, using the first law of thermodynamics, the total heat exchanged by the ideal gas equals the total work done. Thus, we can quantify the efficiency of the Carnot cycle via the heat exchanged...
