China is a developing country with low overall economic development level, backward export commodity structure and low product grade. At present, technical barriers to trade have become a major obstacle to the development of China's export trade. According to the statistics of the 2002 annual academic meeting of China National Intellectual Property Administration Association of Science and Technology, 80% of the world trade barriers come from technical barriers to trade. In recent years, 60% of export enterprises have encountered foreign technical barriers to trade to varying degrees, which has affected 25% of China's total exports. According to the statistics of the Ministry of Commerce, in 2002, six kinds of 2 1 products, such as electromechanical services and light industry, suffered from technical barriers to trade, with business interruption as high as 7 1%, the proportion of products blocked was 39%, and the loss amount was1.70 million US dollars. Technical barriers to trade (TBT) have a long-term negative impact on China's exports, such as reducing the international market share, losing trade opportunities, withdrawing from the market, weakening the competitiveness of China's products, and the decline of foreign consumers' confidence in some agricultural products, especially food. Therefore, it has become an important topic to study the countermeasures of technical barriers to trade in order to promote the development of China's export trade.
