Summary
Chinese cold chain logistics and economy show improving coordination. Key factors like tertiary industry value and GDP drive development, with suggestions provided for future growth.
Area of Science:
- Logistics and Supply Chain Management
- Economic Analysis
- Systems Engineering
Background:
- The integration of cold chain logistics with economic development is crucial for modern economies.
- Understanding the dynamic interplay between these sectors is essential for sustainable growth.
- China's rapid economic expansion necessitates a robust cold chain infrastructure.
Purpose of the Study:
- To construct an evaluation index system for analyzing the coupling relationship between Chinese cold chain logistics and the economy.
- To quantitatively assess the coordination degree between these two systems from 2010 to 2019.
- To identify the primary drivers influencing their coordinated development.
Main Methods:
- Entropy Weight Method (EWM) for determining index weights.
- Coupling Coordination Degree Model (CCDM) to evaluate the interaction.
- Grey Relational Analysis (GRE) to identify influencing factors.
Main Results:
- The coupling coordination degree between cold chain logistics and the Chinese economy exhibited a consistent upward trend.
- The relationship evolved from basic 'coordination' to a higher level of 'good coordination'.
- Key economic indicators (tertiary industry value, GDP per capita, consumption) impact cold chain logistics, while cold chain metrics (storage capacity, freight turnover, employment) influence economic development.
Conclusions:
- A positive and strengthening synergistic relationship exists between China's cold chain logistics and its economy.
- Targeted policy interventions focusing on identified key factors can further enhance coordinated development.
- The study provides a framework and empirical evidence for optimizing the integration of logistics and economic strategies.

01:09Correlation
12.7K
In statistics, two variables are said to be correlated if the values of one variable are associated with the other variable. Depending on the relationship between two variables, correlation can be of three types– positive correlation, negative correlation, and zero correlation.
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:

02:12Short-distance Transport of Resources
16.6K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

01:26Social Exchange Theory
39
As formulated by John Thibaut and Harold Kelley, Social Exchange Theory explains human relationships as economic-like exchanges that maximize rewards and minimize costs. This theory suggests that individuals engage in relationships to gain benefits and reduce burdens, similar to economic transactions. It has been widely applied to various types of relationships, including romantic, professional, and social interactions.Rewards and Costs in RelationshipsRelationship rewards include emotional...

01:27Cold Weather Concreting
127
When freshly poured concrete is exposed to freezing temperatures before it has set, the water within the concrete can freeze. This expansion disrupts the setting process, delays chemical reactions necessary for hardening, and increases the volume of pores within the hardened concrete, which weakens its overall structure. If the concrete manages to reach an appreciable strength before it freezes, the damage can be somewhat mitigated.

01:16Efficiency of The Carnot Cycle
2.9K
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...

Interpersonal relationships progress through stages, beginning with awareness and moving toward mutuality, where emotional connections deepen. While many relationships remain at moderate levels of mutuality, deeper connections form through self-disclosure, trust, and interdependence.Self-DisclosureSelf-disclosure involves revealing personal information, starting with surface-level details and gradually progressing to more intimate content. As trust grows, individuals feel more comfortable...
