Summary
Industrial co-agglomeration shows a U-shaped impact on total factor energy efficiency (TFEE). Green technological innovation mediates this effect, with positive impacts only seen above a specific threshold.
Area of Science:
- Economics
- Environmental Science
- Regional Science
Background:
- Manufacturing and producer services industrial co-agglomeration is crucial for economic transformation and energy efficiency.
- Understanding the complex relationship between industrial co-agglomeration and total factor energy efficiency (TFEE) is vital for sustainable development.
Purpose of the Study:
- To analyze the impact of industrial co-agglomeration on TFEE using spatial econometrics.
- To investigate the mediating role of green technological innovation.
- To explore the nonlinear relationship and regional heterogeneity of this impact.
Main Methods:
- Spatial Dubin model applied to panel data (2004-2019).
- Mediating effect model to assess green technological innovation's role.
- Threshold panel regression to identify nonlinear effects.
Main Results:
- A U-shaped relationship exists between industrial co-agglomeration and TFEE.
- Significant regional heterogeneities observed in TFEE impacts and spatial spillovers.
- Green technological innovation acts as a significant mediator.
- A single threshold effect was found; positive promotion of TFEE occurs above 0.6329.
Conclusions:
- Industrial co-agglomeration's effect on TFEE is nonlinear and context-dependent.
- Green technological innovation is a key pathway for enhancing TFEE through co-agglomeration.
- Policy interventions should consider regional specificities and the co-agglomeration threshold for optimal energy efficiency gains.

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).

01:17Factors Affecting Activity Coefficient
1.1K
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...

The workability of concrete is a critical characteristic that influences the ease of mixing, handling, and finishing the concrete. It is affected by several factors including water content, aggregate properties, and admixtures like air entrainment. Water plays a fundamental role as it lubricates the concrete mix, facilitating easier movement and placement. However, the water requirement varies depending on the texture and shape of aggregates. Finer particles and angular, rough-textured...

The mechanical efficiency of a machine is a fundamental concept that describes how effectively a machine can convert input work into output work. According to this concept, the efficiency of a machine is equal to the ratio of the output work to the input work. An ideal machine, meaning a machine that has no energy losses, has an efficiency of one. This implies that the input work and the output work are equal.
However, in reality, no machine can be truly ideal, and all of them experience some...

22.2K
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.

The power transmission to a factory involves the transfer of apparent power, a combination of active and reactive power. The power factor measures how effectively electrical power is converted into useful work output. The ratio of the real power (KW) that does the work to the apparent power (KVA) supplied to the circuit.
