With economic development and consumption upgrading, there is an increasing demand for cold chain food. At the same time, the impact of epidemics has also brought the safety of cold chain food and medicine into focus, thus highlighting the importance of cold chain logistics.

However, against the backdrop of heightened global uncertainty,cold chain cold chain supply chain security is facing unprecedented challenges. The survival and development of both upstream and downstream enterprises are facing challenges of varying degrees as the flow of goods is blocked, transportation costs increase, and the risk of supply cuts and production stoppages rises.

In order to effectively respond to the cold chain supply chain crisis, stabilize the fundamental role of cold chain logistics in economic development, and build a more resilient and elastic supply chain is imminent. Therefore,cold warehouse it is imperative to strengthen the construction of cold chain logistics!

Cold chain logistics is characterized by "cold" and its soul is "chain". Cold chain logistics is a kind of special logistics, which is established with the progress of science and technology and the development of refrigeration technology. It is a low-temperature logistics process based on freezing technology and refrigeration technology. Generally speaking, refrigerated and frozen foods are always in a specific low-temperature environment in all aspects of production, storage, transportation, sales and pre-consumption, so as to ensure the freshness and quality of foods and reduce the loss of foods in a systematic project.

Unlike ordinary logistics, cold chain logistics is characterized by "cold". Cold environment is crucial for cold chain logistics, which is an important technical means to guarantee the quality of fresh food. The soul of cold chain logistics is "chain", through the "chain" of cold chain logistics to connect fresh food from production and processing to storage and transportation and consumption of various links, to ensure that the cold chain food in the whole cold chain in the closed loop of the safe flow.

Cold chain logistics should first have "things", and then have "flow". Cold chain logistics is essentially for the storage and circulation of physical services. This includes fruits and vegetables stored in a cold chain environment, meat, eggs, poultry, milk, biological medicine and other products, including cold storage, refrigerated trucks, pallets, handling tools and management facilities and equipment. All the "things" form the basis of cold chain logistics.

With "things", there is "flow". Cold chain logistics is a synthesis of logistics, business flow, information flow, technology flow and capital flow. It operates efficiently within a complete set of network system and eventually realizes the enhancement of economic and social values.

To promote consumption upgrade, cold chain logistics guarantees efficient circulation. Consumption is one of the important factors driving GDP growth. Under the influence of epidemic and anti-globalization, the stability and activity of domestic consumption market is particularly important.

In recent years, China's consumption scale has been steadily expanding, the structure continues to be optimized, and the industry is becoming increasingly rich. Developmental and enjoyment-oriented consumption has further grown, and people's demand for high-quality cold-chain food is also increasing. At the same time, the gradual improvement of cold chain logistics infrastructure and service network provides efficient guarantee for the supply and circulation of cold chain food.

Facing the new development situation and environment, the central government has put forward the strategic decision of accelerating the construction of a new development pattern with the domestic macro-cycle as the main body and the domestic and international double-cycle promoting each other. This is a major strategic choice based on the changes in the domestic and international environments in the current and future period, which is conducive to upgrading China's demand structure and improving its supply capacity, promoting the realization of dynamic equilibrium between supply and demand at a higher level and higher level, and enhancing the endogenous impetus for high-quality development.

The key to accelerating the formation of a new development pattern with the domestic macrocycle as the mainstay and the domestic and international double cycle mutually reinforcing is to transform China's advantages in market scale and production system into new advantages for participation in international cooperation and competition. This requires giving full play to the advantages of the super-large-scale market, accelerating the construction of a complete domestic demand system, opening up all links of production, distribution, circulation and consumption, and improving the efficiency of the domestic macro-cycle; at the same time, giving full play to the advantages of a large country in foreign trade, and developing a high level of open economy, so as to form a situation in which the domestic cycle and the international cycle are mutually reinforcing.

Cold chain logistics connects production and consumption at one end. It provides escort for domestic high-quality agricultural products to go out of the country, and also builds a bridge for global cold chain food to enter the domestic market. In the strategy of building a "double-cycle" development pattern, cold chain logistics plays an irreplaceable role and is an important link between domestic and international markets.

In order to better play the role of cold chain logistics in the domestic and international double-cycle, leading cold chain logistics enterprises should be promoted to deeply participate in the global cold chain production and trade organization, strengthen the synergy of domestic and overseas cold chain logistics, procurement and distribution networks, extend the cross-border e-commerce and trade settlement services, and enhance the international supply chain management capability and international competitiveness. Encourage cold chain logistics enterprises and trading enterprises to "go to sea", actively lay out overseas cold chain logistics facilities around the advantageous production areas of global meat, fruits and aquatic products, and carry out international cold chain logistics operations relying on ocean shipping, international railroad intermodal liner and international cargo air transport, so as to build up a network of domestic and international logistics channels, and improve the international development level of cold chain logistics enterprises. In the future, the cold chain logistics will be in the process of constructing a network of logistics channels connecting domestic and foreign countries. In the future, cold chain logistics will show greater value in building a "double-cycle" development pattern.

The construction of a national unified market will promote cost reduction, quality improvement and efficiency enhancement. Under the unified national market, the operation efficiency of cold chain logistics will be greatly improved. Firstly, an open national unified market will effectively reduce the risk of chain breakage caused by midway turnover in cold chain logistics, thus reducing the loss of products during transportation; secondly, the unified market system rules will facilitate the passage of refrigerated trucks, shorten the time wastage caused by frequent stops, and lengthen the quality preservation and freshness of the cold chain food sales cycle; lastly, breaking the local protection and market segmentation is conducive to giving full play to the advantages of cold chain logistics network, and promoting the distribution of high-quality and special agricultural products in a more favorable environment. Finally, breaking local protection and market segmentation is conducive to giving full play to the advantages of the cold chain logistics network, promoting the smooth flow of high-quality and characteristic agricultural products in a wider scope, and effectively stimulating the consumption potential of the domestic market.

Despite many unfavorable impacts, China's cold chain logistics is experiencing a short period of pain and adjustment. However, in the long run, under the multi-wheel drive of continuous policy guidance, market expansion and enterprise innovation and development, the cold chain logistics industry will accelerate its transformation and upgrading, and move towards a new stage of high-quality development. Building a strong cold chain supply chain is the way to implement the new stage of development strategy and meet the needs of economic construction and livelihood protection in the new period.
