Summary
Logistics industrial efficiency along China's western corridor improved, but varies by province. Factors like transport intensity boost efficiency, while urbanization and infrastructure hinder it.
Area of Science:
- Logistics and Supply Chain Management
- Regional Economics
- Environmental Economics
Background:
- The New Western Land-Sea Corridor is a key economic initiative.
- Assessing logistics efficiency is crucial for regional development.
- Understanding factors influencing efficiency is vital for policy.
Purpose of the Study:
- To measure logistics industrial efficiency in 12 provinces along China's New Western Land-Sea Corridor (2010-2019).
- To identify key factors impacting logistics efficiency within this region.
- To propose policy recommendations based on the findings.
Main Methods:
- Employed a three-stage Slack-Based Model (SBM) to measure logistics industrial efficiency, accounting for undesirable outputs.
- Utilized a panel Tobit model to analyze the determinants of logistics efficiency.
- Data spanned from 2010 to 2019 for 12 provinces.
Main Results:
- Logistics industrial efficiency in the region showed improvement over the study period.
- Significant spatial variability in efficiency was observed, with southern provinces generally improving and northern provinces declining.
- Industrial structure, logistics transport intensity, and economic development positively influenced efficiency.
- Urbanization rate, government support, infrastructure level, and openness negatively impacted efficiency.
Conclusions:
- Despite overall improvement, regional disparities in logistics efficiency persist.
- Policy interventions should consider optimizing transport intensity and addressing negative external environmental factors.
- Enhancing pure technical efficiency and scale efficiency is recommended for sustainable logistics development.

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).

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...

01:21Distributed Loads: Problem Solving
703
Beams are structural elements commonly employed in engineering applications requiring different load-carrying capacities. The first step in analyzing a beam under a distributed load is to simplify the problem by dividing the load into smaller regions, which allows one to consider each region separately and calculate the magnitude of the equivalent resultant load acting on each portion of the beam. The magnitude of the equivalent resultant load for each region can be determined by calculating...

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...

01:17Factors Affecting Activity Coefficient

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...
