In recent years, with the steady and rapid economic growth in China, China's foreign trade has increased substantially. It is estimated that the total value of foreign trade import and export will reach US$ 800 billion this year, and China's foreign exchange reserves will also increase substantially. By the end of July, China's foreign exchange reserves will reach $360 billion. Some countries think that China's cheap goods lead to China's huge trade surplus, and China's foreign trade is suspected of dumping at a low price, which is the root cause of the huge foreign trade deficit of some big countries, so people should appreciate their currencies. Even threatened to retaliate against trade. China is still a developing country, and China's economic system is still in the primary stage of market economy, and various legal systems are not perfect. For example, China's stock market is too small, and its ability to raise and finance is limited. The so-called foreign trade surplus refers to the difference between the value of a country's exports and the value of its imports. As a result, the country's foreign exchange income exceeds its expenditure, thus increasing the country's foreign exchange reserves. On the other hand, if the value difference between foreign trade import and export is a deficit. The foreign trade deficit increases foreign exchange expenditure and correspondingly reduces the country's foreign exchange reserves. In recent years, China's foreign trade import and export has increased substantially, and the foreign trade surplus has been increasing. However, China's foreign trade structure is not ideal. First, the proportion of primary products exports is too large, while the proportion of high value-added products is too low and the technical content of products is low. The export proportion of products with high added value and high technology content is low. Second, China's foreign trade foundation is very fragile, and its economic ability to resist risks is very weak. The convertibility of RMB is also a big weakness of RMB. Under the current situation, the RMB is still in a non-convertible state, and it is even less freely convertible under capital account. This shows that China's economy is still very small, and China's foreign trade has a certain surplus, but it is not enough to make the RMB appreciate significantly. Otherwise, China's economy will be violently turbulent, which is not conducive to China's economy and the development of the world economy. A sharp appreciation of RMB is not good for China's economy and the world economy. In fact, China's economy has not developed to that degree, and its ability to resist risks is still very limited. The RMB is still in a non-convertible state, and the China government still needs to master enough foreign exchange reserves to ensure that there is enough foreign exchange for external payment. To maintain sufficient foreign exchange reserves, China's economy must maintain a certain foreign trade surplus, and the necessary management of foreign trade import and export cannot be relaxed for a moment! The China government has repeatedly stated that China will keep the value of RMB relatively stable, which is an unshakable policy of the China government, because it is conducive to the stable and healthy development of China's economy and the stable development of the world economy. At the same time, the China government expressed its willingness to take appropriate measures to solve the trade surplus problem in China, and China has no intention of pursuing a huge trade surplus. Maintaining the relative balance of international trade is the basic policy of China. China reduced the export tax rebate rate, on the one hand, it reduced the financial burden and created conditions for export enterprises to enhance their competitiveness; On the other hand, China will also strive to expand foreign imports and increase imports from the United States and other countries.
