中国对外直接投资与对外贸易关系的实证研究——基于美国、中国香港、越南的合成数据回归分析

由于人民币升值、外汇储备飙升，更多的中国企业选择以对外直接投资的方式参与国际经济分工，对外贸易与对外直接投资的关系也变得愈加紧密和复杂。选取1996-2006年中国对美国、中国香港、越南的FDI流量，进、出口量做合成数据回归分析，结果表明：中国对外直接投资与对外贸易的关系在空间上存在不同，二者关系以及关系强弱因东道国（地区）经济发展水平不同而不同。最后，提出了有关的对策建议。     

Trade Protection in Five EU Member Candidate Countries by Exchange Rate Adjustment,Customs Tariffs,and Nontariff Measures

Five central European candidate member countries for EU accession (Czech Republic, Hungary, Poland, Slovakia, Slovenia = CE-5) entered into the transition period with undervalued exchange rates to stimulate exports and protect domestic industries. However, this policy was not maintained. During 1993–1995, real currency appreciation increased competitive pressure by foreign firms. To protect domestic firms, governments applied high third-country tariffs, temporary import taxes, and numerous administrative barriers to trade. As countervailing pressure by the EU and the U.S. increased and current account deficits soared in 1996 and 1997, the five countries more and more brought exchange rate policies in line with the changes in purchasing power parity.There seems to be a positive correlation between large current account deficits and the more intense use of nontariff protectionist measures. Using exchange rate measures, Slovenia keeps the current account rather balanced. It employs many less nontariff protectionist measures than the other four countries, which show strong tendencies towards real exchange rate appreciation.     

Net foreign assets and macroeconomic volatility

This study analyses the co-movements of net foreign asset accumulation, consumption, real exchange rate, and real interest rate in a cross section of countries. Our sample covers both industrial and developing economies, spanning 1981–2010 period. We find that the accumulation of net foreign assets is associated with increasing consumption and real exchange rate appreciation. In a cross section of countries, when a country increases its net foreign assets to GDP ratio by a one-standard deviation, consumption to GDP increases by 0.02% per year and real exchange rate appreciates by 2% per year. Consumption to GDP responds more positively to net foreign asset accumulation in G7 countries, +0.1 to +0.2% per year, while the response is smaller and negative in developing countries reporting a −0.02% per year. The real exchange rate appreciation, however, is about +3% per year in developing countries and only about +0.2% per year in OECD countries.     

The costs and benefits of exchange rate protection in China

From 2002 to 2011, China ran large surpluses in both the current and capital accounts of its balance of payments, which the People's Bank of China (PBOC) purchased and held at official foreign reserves to avoid nominal appreciation of the currency. Concurrently, with its massive purchases of foreign exchange, the PBOC compelled commercial banks to buy PBOC ‘sterilisation bonds’ and raised commercial bank reserve requirement ratios to avoid monetisation of its foreign exchange purchases and concomitant upward pressure on the price level (that is, real appreciation of the currency). Sterilising foreign exchange intervention, as China did for a decade, constitutes a violation of the implicit rules of a fixed exchange rate regime and as such can be seen as a mercantilist policy of manipulating the real exchange rate to gain, or avoid losing, international price competitiveness—what Corden (1981) termed ‘exchange rate protection’. This paper sets out the simple theory of the costs and benefits of exchange rate protection and provides back‐of‐the‐envelope estimates of their magnitude in China in the 2000s. It also explores the ‘other side of the story’, the decline in US manufacturing employment in the 2000s, which recent literature attributes to a ‘China Trade Shock’ that allegedly resulted from the US granting Permanent Normal Trade Relations (PNTR) to China in 2001. Here, it is argued that the so‐called China Trade Shock resulted from China's sterilised intervention policy, not the granting of PNTR. The implications of these competing hypotheses are considered in the conclusions.     

ON THE RAND: DETERMINANTS OF THE SOUTH AFRICAN EXCHANGE RATE

This paper is an econometric investigation of the determinants of the real value of the South African rand over the period 1984‐2007. The results show a relatively good fit. As always with exchange rate equations, there is substantial weight on the lagged exchange rate, which can be attributed to a momentum component. Nevertheless, economic fundamentals are significant and important. This is especially true of an index of the real prices of South African mineral commodities, which even drives out real income as a significant determinant. An implication is that the 2003‐2006 real appreciation of the rand can be attributed to the Dutch Disease. In other respects, the rand behaves like currencies of industrialised countries with well‐developed financial markets. In particular, high South African interest rates raise international demand for the rand and lead to real appreciation, controlling also for a forward‐looking measure of expected inflation and a measure of default risk or country risk.     

Determinants of Real Chinese GDP 1978–2014

In 2014, the IMF reported that China became the largest economy in the world according to Purchasing Power Parity rates. This study aims to explain the Chinese economic miracle. It focuses on frequently suggested factors influencing China’s real gross domestic product (GDP), such as export promotion, exchange rate policy, and foreign direct investment (FDI). The paper employs the Bounds test of the autoregressive distributed lag (ARDL) model to test for cointegration. Once cointegration is established, Granger Causality is investigated using the vector autoregressive model and the Toda and Yamamoto (1995) method. Two different combinations of the real macroeconomic variables exports, exchange rate, imports, and FDI were employed to examine Granger causal relationships. All explanatory variables, except for the exchange rate, were found to have plausible relationships with GDP. The exchange rate and GDP relationship was unexpected; a Renminbi appreciation was associated with an increase in GDP. To investigate this paradox, a third ARDL model was estimated with exports as the dependent variable and the exchange rate, world GDP, and FDI as the independent variables. In this model, we found evidence of cointegration and a plausible relationship between real exports and the real exchange rate. Exchange rate devaluation increased exports and thus indirectly increased GDP. Such findings help to resolve the unexpected results. Nonetheless, according to the Granger causality tests the established statistical evidence is rather weak. We found that both the exchange rate and FDI are no longer strong drivers of economic growth in China.     

Foreign Transfers and Real Exchange Rate Adjustments in a Financially Constrained Dependent Economy

This paper investigates the role of the real exchange rate in determining the effects of foreign transfers. If capital is perfectly mobile between sectors, a pure transfer has no long-run impact on the real exchange rate. A decline in the traded sector occurs because the transfer, being denominated in traded output, substitutes for exports in financing imports. While a pure transfer causes short-run real exchange appreciation, this response is temporary and negligibly small. Transfers allocated to productivity enhancement do generate permanent real exchange rate adjustments in response to the sectoral reallocation of productive factors. The analysis, which employs extensive numerical simulations, emphasizes the tradeoffs between real exchange adjustments, long-run capital accumulation, and economic welfare, associated with alternative forms of transfers.

Exchange Rate Variability and the Macro-economy: Evidence from Developing and Developed Countries

Abstract

Using annual data, the paper studies the time-series evidence regarding the allocation of fluctuations in the exchange rate between demand components, real growth, and price inflation in a sample of developing and advanced countries. The evidence reveals patterns of interaction between the macro-economy and exchange rate variability. Across developing countries, appreciation decreases the cost of imports and price inflation, while depreciation shrinks the output supply, indicating high dependency on imported goods. The reduction in output supply correlates with higher inflation and an increase in the import value. In contrast, the evidence of the negative effect of currency appreciation on output growth is more prevalent across advanced countries, while depreciation stimulates competitiveness, resulting in higher demand for exports, investment and consumption. Across developing countries, exchange rate variability decreases trend real growth and increases trend price inflation. Across advanced countries, exchange rate variability decreases trend real growth while increasing the variability of price inflation and import growth. Minimizing variability of the exchange rate would be beneficial to sustain higher growth and reduce cyclical variability in developing and advanced countries.

Industry‐specific Exchange Rate Fluctuations,Japanese Exports and Financial Constraints: Evidence from Panel Vector Autoregressive Analysis

Using a panel vector autoregression approach and industry breakdown data for financial constraints obtained from the Bank of Japan's Tankan (Short‐Term Economic Survey of Enterprises in Japan) database, this study empirically investigates whether and how Japanese firms' financial constraints (internal and external) influence the response of Japanese sectoral exports to an exchange rate shock. Furthermore, we use the industry‐specific real effective exchange rate data developed by to allow for different movements of real effective exchange rates across industries. It is found that financial constraints have a significant influence on Japanese exports in response to exchange rate shocks. Japanese exporters with either lower internal financial constraints or external financial constraints are less affected by the yen's appreciation. In addition, if firms face high external financial constraints, only reducing the internal financial constraints cannot help them mitigate the impact of the yen's appreciation on their exports. Thus, an accommodative financial environment also plays an important role in alleviating the impact that the yen's appreciation has on Japanese exports.     

本币升值影响外汇储备的实证分析:2003～2007

本文以2003～2007年13个国家为研究对象,研究了不同国家本币升值对外汇储备的影响。面板数据的实证结果表明,汇率波动在一定程度上决定了一国外汇储备的规模,本币升值是导致2002年以后新兴市场国家外汇储备快速增长的重要因素,本币升值幅度与外汇储备的增幅成反比。我们认为,外汇储备管理应从控制供给入手,有效控制外汇储备规模。而央行减少对汇率的干预,并逐步推进人民币国际化是有效降低过多外汇储备的重要手段。     

Government Spending Patterns and the Real Exchange Rate in Sub‐Saharan Africa

Do government spending patterns and composition influence the behaviour of the real exchange rate in sub‐Saharan Africa (SSA)? First, we present a two‐sector small open economy model which proposes that government spending together with productivity differential leads to real exchange rate appreciation. Then, we take these propositions to SSA data and perform a coordinated empirical analysis. Interestingly, we find empirical support for the propositions in SSA. Finally, we disaggregate government spending into three components—consumption, investment and transfer payments—and check whether the composition of government spending provides any insight into the behaviour of the real exchange rate in SSA. Our results suggest that government composition does influence the real exchange rate in SSA. Specifically, we find that government consumption induces a real appreciation while government investment leads to a real depreciation. Although these findings yield appropriate magnitudes and signed directions, their effects are not always significant.     

人民币汇率的长短期影响因素对比分析和汇率波动主导因素界定

论文采用2000-2013年间的月度数据,构建了马尔科夫区制转换模型,在此基础上研究了人民币汇率的长短期影响因素,实证结果显示,短期影响因素中国内通货膨胀、国际市场利率和国内利率的一个正向冲击在10个月的反应期内能造成人民币汇率升值或贬值的累积值分别达到约0．75、0．35和0．9。长期影响因素中贸易条件、货币供给和外汇储备的一个正向冲击在30个月的反应期内能造成了人民币汇率升值或贬值的累积值分别达到约5．5、5．5和16。然后结合模型区制间转换累积脉冲响应和模型区制时间分布可以确定我国某一时期汇率变动的主导因素。分析发现,2007年5月-2008年4月这一时期我国汇率升值变动主要由短期因素决定,2011年3月-2012年1月这一时期我国汇率升值变动却主要由长期因素决定,说明我国不同时期汇率变动趋势决定因素可能不一致。     

Capital flows and real exchange rates in emerging Asian countries

This paper examines the impact of capital flows on real exchange rates in emerging Asian countries during 2000–2009 using a dynamic panel-data model. The estimation results show that the composition of capital flow matters in determining the impact of the flows on real exchange rates. Other forms of capital flow, especially portfolio investment, bring in a faster speed of real exchange rate appreciation than foreign direct investment (FDI). However, the magnitude of appreciation among capital flows is close to each other. The increasing importance of merger and acquisition (M&A) activities in FDI in the region makes these flows behave closer to other forms of capital flow. The estimation results also show that during the estimation period, capital outflows bring about a greater degree of exchange rate adjustment than capital inflows. This evidence is found for all types of capital flow. All in all, the results indicate that the swift rebound of capital inflows into the region could result in excessive appreciation of (real) currencies, especially when capital inflows are in the form of portfolio investment.     

Real exchange rate determination in eastern Europe

This paper develops a simple theoretical model of exchange rate determination in a transitional economy. The distinguishing feature of the model is the retention of market failures pertaining to the production and consumption of nontradable goods and, therefore, the likelihood of real exchange rate appreciation. Using this framework, the econometric tests are performed for the Czech Republic, Slovenia, Poland, and Hungary, and appropriate macroeconomic and exchange rate policies are recommended to support further liberalization and development of the foreign exchange market.     

Three current account balances: A “Semi-Structuralist” interpretation

Three current account imbalances – one very large deficit (the United States) and two surpluses (Japan and the Euro area) – are subjected to a minimalist structural interpretation. Though simple, this interpretation enables us to assess how much of each of the imbalances require a real exchange rate adjustment. According to the estimates, a large part of the U.S. current account deficit (nearly 2 percentage points of the 2006 deficit of 5(1/2)% of GDP) will undergo an adjustment process that involves real depreciation in its exchange rate. For Japan, a little more than 1 percentage point (of GDP) of the current account surplus is found to require an exchange rate movement (real appreciation) as the surpluses adjust down. For the Euro area, less than half a percentage point of its current account surplus is found to require an adjustment via real appreciation.     

人民币升值对我国资产价格波动的影响

随着我国经济持续增长和外汇储备的逐年增加,人民币升值步伐有越来越快的趋势。自2005年7月,我国宣布结束维持十年之久的人民币汇率盯住美元政策以来,人民币已累计升值30%。人民币升值导致了我国资产价格的波动,特别是我国股票和房地产价格的起伏波动。如何应对由人民币升值引起的国内流动性过剩导致资产价格波动,成为政府面临的新挑战。     

Can Renminbi Appreciation Reduce the US Trade Deficit？

I. Introduction The trade relationship between the USA and China has been contentious during the past several decades since China’s economic reforms in 1978. The trade relationship between the two countries has been strongly constrained and highly politically influenced. Figure 1 depicts US–China trade from 1994 to 2004. US imports from China have been far greaterthan US exports to China over the past 10 years, and the corresponding US trade deficits with China have become increasingl…     

Free trade zones,tariffs and the real exchange rate

This article examines the consequences of changes in final and intermediate good tariffs on structural adjustment, urban unemployment, and the real exchange rate in the presence of a free trade zone (FTZ) and foreign capital in the host country. The location of the FTZ and the disaggregation of the economy allows us to examine the consequences of a tariff change on regional incomes. It is shown that as a consequence of a tariff change the urban and rural incomes need not necessarily move in the same direction (hence the potential for rural and urban conflict in policy making). It is also shown that an increase in the tariff on an immediate good may result in both export promotion and an increase in welfare. Such expansion is a nonconventional result, since raising barriers to trade normally leads to a contradiction in the volume of the trade. The interconnection between the real exchange rate and intermediate good tariff is also explored in this article. It is shown that a policy of imposing tariffs on these goods may result in the appreciation of the real exchange rate.     

Reverse imports, foreign direct investment and exchange rates

This paper investigates linkages among “reverse imports”, foreign direct investment and exchange rates. As an example, we have in mind the competition in the Japanese market of a Japanese multinational firm and a Chinese domestic firm. Products are differentiated based on Japanese consumers’ brand name recognition. The model shows that yen appreciation leads to an increase in Japanese production in China and “reverse imports” and a decrease in Japanese domestic production. Due to the barriers in brand name, the exports of the Chinese firm could fall, because the increase of reverse imports may erode the market share of the Chinese firm, even though total exports from China increase. Further, we find that yen appreciation may improve the profits of the Japanese firm and welfare in Japan under reverse imports, against conventional wisdom. The predictions of the model fit well with the actual numbers and shed light on the current debate on the Chinese currency.
