Studies On The Scientific Technology Support System In China's Food Import And Export Trade

China is a big country for food production and consumption, and also a big trading partner for food. In recent years, more and more developed countries set up technical barriers with increasing number of requests for inspection and quarantine to trade in the name of the prevention of epidemic diseases, protecting human and animal and plant life and health. China's exports of food products are rejected frequently. At the same time, we are facing great challenges from the security of imported food. The imported food frequently are often detected pesticides residues, veterinary drugs residues, disease-causing micro-organisms, heavy metals residues and other hazardous substances by the inspection and quarantine agencies.In view of the increasing concern onfood safety from consumer, the number of WTO/SPS notifications relating to food safety increases fast in international food trade. It has reached a consensus that the improvement of food safety is based on scientific and technological development.The growing importance of hazard analysis application in food safety has been highlighted. The developed countries are devoting to the research on food safety and technology support system and thus expect to achieve initiative place in the international food trade.Firstly, more systematic, in-depth analysis of China's recent import and export food safety issues was carried out in this paper. We take Japan's "Positive List System" and the European Union's new food safety laws and regulations as the main cases to analyze the new requirements in international food trade. An gravity model was ysed to empirically analyze the impact of the new requirements on China's tea exports. It revealed that the scientific and technological progress was the only way to widen the international food trade. The future trend of China's import and export food safety issues was studied based on the analysis above. It showes that possible more safety problems in food will appear with the growing need of food in China. We are facing great challenges in food trade in the futrue because major critical issues of food safety technology has not been fundamentally resolved,such as environmental pollution and pollution mitigation.Secondly, the construction of the technology support system in food safety was investigated to understand the relation between the food safety control and scientifc technical support. The main advancement of some developed contries in the technologies of food safety was also discussed. We can conclude that the scientific risk assessment techniques , surveillance techniques, early warning techniques and food traceability overall control technology will take more important roles in the future food trade .The experience in building and technology support system from developed countries was summed up and the future development trends in the import and export food safety were disscussed. The composition and characteristics of our import and export food safety and technology support system was analyzed based on the global food safety management model. The differences between the technology needs of ours and the international food safety requirements were discussed by taking the detection technologies of hazard substances residues. We should follow the international advanced scientific and technological developments in food safety to find the key techniques affecting the food safety in our country. Aiming at the challenges we are facing, we should give priority to food-borne hazards risk assessment techniques, develop more reliable, fast, portable, accurate food safety testing technology, accelerate the development of major pollutant residue control technology and carry out the process control technology in food production, processing, storage, packaging and transportation. The measure above is very important for import and export food safety to satisfy the needs of building a moderately prosperous society.Then, more detail analysis on the gap with the developed countries in the the four levels including food safety technology or technical standards, inspection and quarantine facilities and the quality of personnel was done to put forward a policy framework for improvement of import and export food safety and technology support system in China. Finally, the key issues concerned were raised on the basis of the summary of national science and technology investment, output and Identification methods of the achievements: 1) setting inspection and testing agencies and integration of the inspection and testing resources in a reasonable way; 2) strengthening the studies on core detection technology; 3) promoting the building of third-party testing institution and 4) development of food safety soft science research.We hope that the research above can provide some useful suggestions to improve our existing import and export food safety risk early warning and rapid response mechanism and the level of China's food safety management. It is targeted to change the working pattern of our food quality and safety supervision from"negative, passive, afterwards and making up"into"positive, initiative, beforehand and prevention".
