In recent years, with the steady development of our economy, the people’s living standards have been greatly improved and the concept of consumption has developed in the direction of diversification and rapidity. The demand for refrigerated transport has greatly increased. According to relevant data, at present, approximately 85% of meat, 77% of aquatic products, and 95% of fruits and vegetables in China are basically transported at room temperature. Only about 12 million tons of fruit rot per year. Vegetables rot 130 million tons. China's cold chain has not yet formed a complete system. The circulation and storage efficiency and benefits from the starting point to the consumption point cannot be controlled and integrated. 
In the future, the analysis of the efficiency of highway cold chain transportation in China will be based on transportation methods. There are four major ways: highways, railways, waterways, and aviation. Highways and railways are the main modes of transport. By 2009, there were 6,587 railroad freezers across the country, accounting for Of the rail freight cars, 1.1%, and the number of highway refrigerated trucks is around 50,000, which only accounts for 0.3% of freight cars. Due to the restriction of domestic railway resources, it is difficult for railway refrigerated transport and road transport to coordinate with each other, and it has also become one of the factors that seriously affect the efficiency of refrigerated transport.
The share of road transport continues to rise. At present, there are more than 50,000 refrigerated and insulated vehicles in China, and only a small part of these are professional refrigerated vehicles equipped with refrigeration equipment and capable of reaching a certain scale and tonnage. In the United States, there is an average of one refrigerated truck per 500 people. Taiwan is 1,000 people in China, but the number of per capita refrigerated cars in China is far below this level. China's refrigerated and insulated vehicles account for only 0.3% of freight cars, the United States is 1%, Germany and other developed countries are 2% -3%.
The market demand for food refrigerated trucks has gradually increased. In terms of refrigerated transport, road refrigerated transport has obvious advantages in terms of networks and sources of supply. Highway networks are more developed than railways, aviation, and other networks, and are also more organized than other modes of transport. easy. Compared with aviation cold chain and land-water cold chain, the low cost of road transport is undoubted. Compared with the railway cold chain, the study found that the transportation mileage is less than 800 kilometers, and the road transport is the most economical; the transportation process exceeds 800 kilometers. The railway has a more cost advantage. Therefore, on the whole, on the short-term perspective, highway cold chain transportation costs are relatively low.
Due to its convenient and flexible features, refrigerated cars play an increasingly important role in the refrigerated transport in China. In the next few years, the proportion of highway refrigerated transport volume in China's refrigerated cargo will continue to increase. In the future, more refrigerated and insulated vehicles will be required to meet the growing demand for cold chain logistics.
The refrigerated truck is a kind of special special vehicle developed with the demand of refrigeration technology. As the demand for cold chain in China continues to increase, the demand for refrigerated trucks will also increase substantially in the future. Among them, midsize cars will be replaced by light, micro and heavy vehicles. New energy refrigerators such as liquid nitrogen, carbon dioxide, and cold storage plates will become more popular. With the improvement of environmental protection requirements, the new fluorine-free refrigerated truck produced with new fluorine-free materials and new production technology will have a broad market prospect.
In terms of highway refrigerated transport, the major transportation areas are concentrated in the Yangtze River Delta, the Pearl River Delta, and the Bohai Rim. The common feature of these three regions is that the economy is relatively developed and residents have a strong demand for refrigerated food. At present, China's highway cold chain logistics has not yet formed a unique competitive situation. Major cold chain logistics companies include Shandong Rongqing, Tianjin Kangxin, Henan Shuanghui Logistics, Yonggui Refrigeration, Chongqing Xuefeng, and Sinotrans Shanghai Cold Chain. Logistics Co., Ltd., Beijing Huari Flying, Beijing Express Line Food Logistics, Henan Huaxia Express Logistics Co., Ltd., etc.
At present, the market for cold chain logistics in the South is almost monopolized by road transport, and many long-distance, high-value-added roads for fruits and vegetables also have large transportation volumes. About 3/4 of the transport of perishable goods such as fruit and vegetables is occupied by roads, and short-distance transport is almost entirely covered by highways.
