Summary
Global carbon total factor productivity (CTFP) shows an upward trend driven by technology, but significant regional disparities exist and are expanding. Strategies focus on technological advancement and regional convergence for sustainable development.
Area of Science:
- Environmental Economics
- Sustainable Development
- Productivity Analysis
Background:
- Assessing global carbon total factor productivity (CTFP) is crucial for mitigating global warming and promoting sustainable development.
- Effective CTFP assessment aids in slowing global warming and fostering green transformation globally and regionally.
Purpose of the Study:
- To measure and analyze global carbon total factor productivity (CTFP) from 1991 to 2019.
- To examine the spatial characteristics, regional disparities, and influencing factors of global CTFP.
- To propose strategies for enhancing global CTFP and promoting sustainable development.
Main Methods:
- Constructed a CTFP evaluation index system and employed the SBM-DDF-GML productivity index model for precise measurement.
- Utilized ArcGIS and the Dagum Gini coefficient method to analyze spatial characteristics and regional disparities.
- Applied σ-convergence and β-convergence models to investigate influencing factors and convergence trends.
Main Results:
- Global CTFP demonstrated an overall fluctuating upward trend, primarily driven by technological progress.
- Significant and expanding gradient disparities in global CTFP were observed, stemming from supervariable density and regional differences.
- While no clear σ-convergence was found, significant absolute and conditional β-convergence trends in CTFP were identified.
Conclusions:
- Strengthening R&D is key to improving CTFP and driving sustainable development.
- Encouraging regional convergence can effectively reduce development disparities.
- Enhancing dynamic monitoring and evaluation systems is vital for fostering equitable CTFP growth.

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).

01:14The Carbon Cycle
39.8K
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.

01:17Factors Affecting Activity Coefficient
927
The extended Debye-Hückel equation indicates that the activity coefficient of an ion in an aqueous solution at 25°C depends on three partially interdependent properties: the ionic strength of the solution, the charge of the ion, and the ion size.
The activity coefficient value for an ion is close to one when the solution has almost zero ionic strength, i.e., when the solution shows close to ideal behavior. As the ionic strength of the solution increases from 0 to 0.1 mol/L, a...

Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

01:06Primary Production
23.9K
The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.

01:19Turnover Number and Catalytic Efficiency
10.7K
The turnover number of an enzyme is the maximum number of substrate molecules it can transform per unit time. Turnover numbers for most enzymes range from 1 to 1000 molecules per second. Catalase has the known highest turnover number, capable of converting up to 2.8×106 molecules of hydrogen peroxide into water and oxygen per second. Lysozyme has the lowest known turnover number of half a molecule per second.
