Problems: Nowadays, China's cold chain industry is taking a big stride forward under the support of policies. However, due to the late start, many industry problems are still not completely solved, and there is still a big gap between the developed countries in the world. With the high-speed expansion of the market and the enterprises, the five major problems restricting the development of the industry always remain to be solved.

1, the cold chain system has not yet been built at present, about 85% of China's meat, 77% of aquatic products, 95% of the vegetables and fruits are basically room temperature transportation sales, each year, only the fruit rot nearly 12 million tons, vegetable rot 130 million tons, serious economic losses. As far as developed countries are concerned, Canada has formed a complete cold chain logistics system for agricultural products, and the loss of vegetable logistics is only 5%. At present, the establishment of China's cold chain system needs strong support from the government.

2, cold chain facilities are relatively backward in recent years, China's cold chain infrastructure is growing rapidly, but relative to China's large population base, cold storage and refrigerated trucks and other resources per capita occupancy is still on the low side, part of the infrastructure is obsolete and uneven distribution, urgently need to be upgraded.

From the transportation situation, by China's railroad resources and other factors, railroad refrigerated transport and road refrigerated transport is difficult to synergize, seriously affecting the efficiency of refrigerated transport.

3, cold chain third-party logistics development lags behind at present, China's third-party cold chain logistics development of the basic situation is to food production enterprises as the mother of the third-party logistics enterprises and independent third-party logistics companies **** exist and progress. Professional third-party cold chain logistics accounts for about 20%, dominated by small and medium-sized enterprises, and lacks industry competitiveness.

4, cold chain system standardization needs to be improved according to incomplete statistics, distributed in different industries and departments of the cold chain logistics standards have reached nearly 200,

while the cold chain logistics industry involved in various industrial and technical organizations, scientific research institutions, are scattered in various government departments, various industries, which results in the difficulty of communication and cooperation between each other, and can not form a unified planning.

5. Low level of informatization Cold chain logistics is different from ordinary logistics, its hardware level and cargo operation requirements are more rigid than those of ordinary cargoes. The overall level of logistics informatization in China is low, and the current status of informatization in the cold chain transportation industry is even more unpromising. Most of the operation personnel are changed from general logistics, not only unfamiliar with the product characteristics, but also have a lower degree of mastery on the operation requirements of cold chain logistics. Therefore, the ability of cold chain logistics emergency planning needs to be improved.
