人民币汇率与中美贸易收支的关系研究
[Abstract]:Since China joined the WTO in 2002, the trade surplus between China and the United States has been enlarging. In recent years, the western countries led by the United States frequently blamed China for manipulating the exchange rate of RMB. They blamed the trade imbalance between China and the United States on the low exchange rate of RMB. They believed that the manipulation of the exchange rate of RMB and the serious undervaluation of the exchange rate of RMB directly led to the huge trade deficit of the United States. For this reason, the United States has been pressing China to adjust the exchange rate of the RMB, forcing the RMB to appreciate substantially. In 2011, the United States pressure on the appreciation of the RMB set off a climax, the RMB exchange rate issue has once again become a focus of attention between China and the United States.
The persistent trade imbalance between China and the United States seriously affects the normal trade exchanges between the two countries, which is not conducive to the economic stability and development of the two countries. Easy balance and other factors affecting Sino-US trade balance provide the basis for policy choices to alleviate Sino-US trade imbalance, which is of great significance to the harmonious development of Sino-US economic and trade.
Before 1994, there was a double exchange rate in China. In 1994, the exchange rate of RMB was unified. The official exchange rate of the new RMB was greatly depreciated to 8.7 RMB against the US dollar. During the following ten years, the exchange rate of RMB remained stable, fixed at the level of 8.28 RMB against the US dollar. However, the trade surplus increased significantly, and then the total trade surplus increased and decreased from time to time. The Sino-US trade surplus gradually expanded after 1994, and the Sino-US trade surplus increased rapidly after 2002.
In 2005, the central bank introduced a new exchange rate policy. The RMB exchange rate was no longer pegged to the US dollar alone, forming a more flexible exchange rate system. On the day of the exchange rate reform, the RMB exchange rate was 8.11 yuan to the US dollar, and the appreciation rate was 2.1 percentage points. Since then, the RMB has entered the appreciation channel. On May 15, 2006, the RMB exchange rate against the US dollar "broke 8", and on May 5, 2008. The RMB exchange rate against the US dollar "broke 7" in January. Due to the impact of the financial crisis, the RMB stopped appreciating from the second half of 2008 to May 2010. However, the RMB exchange rate against the US dollar remained at the level of about 6.82 RMB against the US dollar for nearly two years, and the RMB exchange rate rose again. In December 2010, the RMB exchange rate against the US dollar was 1. The exchange rate between the US dollar and the US dollar was 6.6227 yuan and 6.3009 yuan in December 2011. By $296.46 billion, the trade surplus had declined, and the balance of trade between China and the United States had gradually expanded between 2006 and 2008, but declined during the relatively stable period of the RMB exchange rate in 2009, and then continued to climb.
Traditional trade theory holds that currency depreciation improves trade balance and currency appreciation aggravates trade balance. However, according to the above data, we find that the imbalance of trade balance between China and the United States has not been improved because of the appreciation of the RMB. Since the RMB entered the appreciation channel, China's trade surplus with the United States has maintained an expanding trend, and the trade surplus between China and the United States has maintained an expanding trend. The trade surplus has not gradually narrowed because of the appreciation of the RMB. So why does the appreciation of the RMB not reduce China's surplus with the United States and what impact does the exchange rate of the RMB have on the trade surplus between China and the United States deserve our discussion and study.
Foreign theories on exchange rate and trade balance include price-cash automatic adjustment mechanism, Marshall-Lerner condition, J-curve effect and McKinnon's exchange rate and trade balance theory. The Marshall-Lerner condition points out that only when the absolute value of the elasticity of price demand of imported commodities and that of price demand of export commodities is greater than 1, the devaluation can improve the external trade balance. The J-curve effect holds that the Marshall-Lerner condition, even if it holds, will depreciate in the short run. It can not necessarily improve a country's trade balance; absorptive analysis takes the output, national income and expenditure of a country into account in the relationship between exchange rate and trade balance; McKinnon's exchange rate and trade balance theory combines the elasticity analysis method and absorption analysis method, respectively, in closed economy and open economy. The impact of rate on trade is studied.
The appreciation of the RMB today is similar to the appreciation of the Japanese yen 30 years ago, and the US pressure on the RMB is similar to what Japan did more than 30 years ago. With the rapid expansion of foreign trade and the filling of European and American markets with Japanese manufactured industrial goods, the United States, with stagnant economic growth, rising unemployment rate, a serious current account deficit and imbalances in foreign trade, especially the extremely serious trade deficit between the United States and Japan, began to intervene in Japan's export policy, forcing Japan to raise the yen-to-Japan ratio. The US dollar exchange rate attributes the trade imbalance between Japan and the US to a serious undervaluation of the Japanese yen against the US dollar in an attempt to alleviate the trade imbalance between Japan and the US through the appreciation of the Japanese yen. Japan's economy has not recovered from the "lost decade". Through the history of the appreciation of the yen, we can see that the appreciation of the yen did not reduce Japan's trade surplus with the United States, but gave a heavy blow to the Japanese economy. Experience and painful lessons deserve China's vigilance, and Japan's tragedy must never be staged in China.
In order to study the relationship between RMB exchange rate and Sino-US trade balance, this paper reviews the RMB exchange rate regime and China's trade balance, and makes a qualitative analysis of the relationship between RMB exchange rate and China's trade balance in four stages by combining text and chart.
Next, this paper selects the monthly economic data from 1995 to 2011, uses co-integration test, error correction model and Granger causality test to explore the relationship between RMB exchange rate and Sino-US trade balance through quantitative analysis.
This article is divided into seven chapters. The chapters are arranged as follows:
The first chapter is the introduction, which mainly introduces the background and significance of the topic, expounds the general trend and current situation of RMB exchange rate and trade volume, and introduces the main content, structural framework, innovation and shortcomings of the article.
The second chapter is the exchange rate and trade balance theory and literature review, mainly introduces the price-cash automatic adjustment mechanism, Marshall-Lerner condition, J-curve effect and McKinnon exchange rate and trade balance theory. Research on the relationship between RMB exchange rate and China's trade balance and the relationship between RMB exchange rate and China-US trade balance.
The third chapter mainly studies the relationship between the sharp appreciation of the yen and the trade balance between Japan and the United States since the 1970s, and expounds the background of the appreciation of the yen and its impact on the Japanese economy.
Chapter Four and Chapter Five study the relationship between RMB exchange rate and Sino-US trade balance through qualitative and quantitative methods respectively. In Chapter Four, we analyze the relationship between RMB exchange rate and China's trade balance qualitatively by combining text and chart. The results show that RMB exchange rate has limited influence on Sino-US trade balance. Using monthly economic data from 1995 to 2011, this paper studies and analyzes the relationship between RMB exchange rate and Sino-US trade balance by empirical method. The co-integration test results show that there is a long-term equilibrium relationship between RMB exchange rate and Sino-US trade balance. However, the coefficients of the standard co-integration equation show that the RMB exchange rate is related to Sino-US trade balance. The effect is far less than the effect of the real GDP of the United States on the trade balance between China and the United States. From the error correction model, we find that there is a slight J-curve effect on the trade balance between China and the United States. Granger causality test shows that there is no causal relationship between the exchange rate of RMB and the trade balance between China and the United States. It proves that RMB appreciation can not solve the problem of Sino US trade imbalance.
Chapter 6 is about other factors that affect Sino-US trade balance. Since the RMB exchange rate has a very limited impact on Sino-US trade balance, this chapter further explores other factors that affect Sino-US trade besides exchange rate. The trend line of the proportion of import and trade balance to GDP is almost the same, which shows that the excessive consumption and low savings rate in the United States are one of the reasons for the trade deficit of the United States in the past two decades. At the same time, the adjustment of the world industrial structure and the import restrictions imposed by the United States on China are the factors causing the Sino-US trade imbalance. The United States has overestimated the US trade deficit with China.
The seventh chapter is the policy suggestion. The appreciation of RMB exchange rate can not effectively balance the trade balance between China and the United States. The article puts forward corresponding policy suggestions. China not only needs to urge the United States to gradually improve its export control policy to China and increase the savings rate of the United States, but also needs to expand domestic demand, improve the Sino-US trade structure and speed up the people's life. Reform of the exchange rate system.
There are three innovations in this paper. First, this paper uses text, data and charts to analyze the relationship between RMB exchange rate and Sino-US trade balance by combining qualitative and quantitative methods. The conclusion is that RMB exchange rate has a limited impact on Sino-US trade balance. At present, RMB appreciation can not promote Sino-US trade balance. Second, this paper uses the monthly economic data from 1995 to 2011 to model and analyze, overcomes the shortcomings of selecting too few sample points caused by annual or quarterly data. Third, many studies only discuss the relationship between exchange rate and trade balance, but this paper discusses other factors affecting Sino-US trade balance in detail.
