摘要

本文试图考察变化和波动之间的关系来分析中国的人民币汇率和其农业出口。建立了一个模型来分析人民币汇率影响农产品出口所面临两个运动约束包括中国特定的汇率制度和存在技术性贸易壁垒的农业贸易。该模型表明,民币汇率的影响运动依赖汇率水平的比较(升值或折旧)效应和汇率风险的效果。以中国农产品出口日本为例,实证检验以中国对日本农产品出口为例，进行了实证检验。一个模型（1，1）指定衡量汇率波动和日常生活的回归与结构打破虚拟变量估计基于单位根检验结果与结构。结果表明人民币兑日元升值将促进出口增长，与积极汇率波动促进农产品出口到日本而阻碍出口。然而，汇率波动对出口影响远小于汇率水平，从而导致消极的净出口政策对农产品出口的影响实证结果进行了讨论。

前言

改革开放以来中国在2005年七月人民币汇率形成机制，人民币已波动频繁。在这方面，密切关注了对人民币汇率的影响波动对中国出口的影响。由于每个行业都有自己的特点，其汇率变动可能对不同的行业有不同的影响。因此，克莱因（1990）指出，影响实际汇率波动对出口贸易在商品的水平下必须进一步调查，。一般来说，农产品有相对于制成品，和为较低的初始投资成本，存在的长期合同等这样的行业性质特殊。人们普遍承认，影响汇率变动对农产品贸易的不同，对制造品贸易也不同。经谢尔登和马克克劳斯顿（2002）证实，相对于其他行业，实际汇率不确定性具有较显著的负向影响农产品贸易的作用。至于中国，什么是影响人民币升值和相关的风险volatility1其农业出口？一个对这一问题的研究具有重要的理论和现实意义。一方面，目前还没有出现明确的理论和实证结论对贸易影响汇率波动的经济共同体。此外，大量的研究探讨贸易影响汇率波动在发达国家，忽略了对它们在中国这样的发展中国家的研究。发展中国家与发达国家不同的特点，如不同的汇率制度，缺乏完善的远期外汇市场，缺乏有效的金融衍生工具等，这都严重限制出口商的行为。在中国，有两点重要的限制：第一，中国运行特定的外汇管理体制；其次，中国农产品出口遇到了严重的技术性贸易壁垒，卫生和植物检疫。这意味着贸易影响汇率变动在发展中国家不应该被忽视；另一方面，当前人民币升值会带来一定的负面影响，中国的农业经济和农民的福利（李岗，2006），而在中国大多数人口仍然是农民。因此，探讨影响人民币汇率变动对农产品出口具有极其重要的现实意义。基于上述认识，本文，以中国对日本农产品出口为例，试图解释人民币汇率水平的变化和波动对中国农产品出口的影响。

1.文献回顾

汇率变动对农产品贸易影响的研究首先由舒（1974）展开，交换率汇率波动被定义为相关的风险与意外的动作的汇率（麦肯齐，1999）。基本参数作为一个重要的变量在经济分析美国农业部门。在他开创性的研究中，有相当数量的定量评估的研究影响名义和实际汇率对农产品贸易的案例。不同的实证方法和汇率变量中都使用了这些研究，因此达成共识：汇率波动大大阻碍了农业贸易流动，相比其他贸易，这种负面效应更明显。一些实证研究比较了不同的汇率变动对经济包括在农业部门和其他部门的影响。这些研究得出了类似的结论，即：总的来说，汇率的变化对农产品贸易不利影响显著。经Gervais,Larue &奥利弗(2004),马修,特里和Agapi(2006)调查，汇率变动对农产品贸易的影响在部门和产品级两方面。Susanti（2001）研究了印度尼西亚的总出口额和五个主要农产品出口显示，他们对印度尼西亚汇率变动均有显著的不利影响。从早期的调查，罗伯特和李察（1981）对美国的小麦，棉花和大豆最近的调查，及辜（2006）和李与李（2005）对大豆的调查，研究人员调查了一些国家对其主要农业贸易流对汇率变动的影响，包括大麦，小麦，猪肉，棉花，咖啡，可可，生猪，玉米等。这些研究都支持农产品贸易的分类对汇率变动有负面影响这一结论。然而，一些研究（如安达加西亚，1989；abdulkudos，2003）表明，在一定的农业产品分类下，汇率变动各不相同的国家影响不同。在一个时代的浮动汇率制度下，在这样一个时代的浮动汇率制度,有截然不同的观点在理论上如果波动性汇率风险阻碍国际贸易:一些模型的负面假设找到支持而其他模型导出了支持积极的假说。实证研究的结果都是集中在交易所波动率均不让人困惑,但他们大多支持阴性效果。谢尔登(2003),Gervais,Larue和奥利弗表明,(2004)的风险等汇率波动明显减少农业贸

易流程。然而,金,想和辜(2003)显示的影响是否汇率波动是积极的还是消极的相关测量的影响波动和第三世界国家。许多中国学者已经在调查的影响人民币汇率变化对中国农产品贸易集中在两个方面。一个是估计J-curve效果和汇率弹性的进口和出口的农业产品,包括Cai的早期研究(1994),顾,李和阐释(1994)和最近的研究的歌》(2005)和朱田和小王(2006)。另一个是模拟人民币升值的影响对中国农产品进口和出口在宏观模型,重点在不同的环境影响。尽管上述的研究取得了较大的成功,依然存在一些应注意的问题。第一、理论模型的基础上对发达国家的假设并不一定适合发展中国家,因此需要在发展这些模型假设的基础上,发展中国家;第二,要注意可能产生过程中数据的结构打破，为了防止“伪协整”;第三在未来的研究,发展中国家应受到更多的关注。发展中国家与发达国家之间的汇率制度仍有一个大的差异, 在发展中国家的经济发展农业出口扮演了重要的角色。

结论

本文初步探讨关系变化和波动(风险)的中国人民币汇率和其农业出口。实证结果表明,人民币升值的汇率形成机制改革后,2005年7月,具有显著的负面影响,对中国农产品出口而汇率波动的风险,总的来说,具有显著的正面影响。然而,汇率风险效果来说要小得多的汇率水平变化,汇率波动的影响最终都有一种占主导地

位的后者,这意味着人民币升值仍然是一个主要的因素在决定中国农业出口到日本。

因此,人民币汇率的负面影响运动在中国农业出口不应被低估。这很重要,政府调整其政策。由于汇率政策调整困难,政府开始从农业政策调整以减少或缓解汇率波动的负面效应。根据主导的负面效应的人民币升值压力,政策调整,在短期内是进一步提高农业出口的支持系统,降低单位成本的农业出口。而长期的政策调整在于提高服务质量、改善农业产品的技术进步,这将提高价格竞争力质量竞争力。此外,特别注意到汇率风险。虽然本文发现名义汇率波动的风险产生积极影响中国农产品出口到日本,这种可能性,大多数中小制造商,将风险降低出口令人厌恶的面对的风险增加汇率,也不能除外,因为总体数据的使用。因此,政府也不能忽视外汇市场稳定。与此同时,提供政策指导和金融工具的外汇风险令人厌恶的同样重要的是要减少出口商汇率风险和保持稳定农业出口增长。

Abstract

This paper attempts to examine the relationship between changes and volatility of China's RMB exchange rates and its agricultural export. A model is constructed to analyze the effect of RMB exchange rate movements on agricultural exports facing two constraints including China's particular exchange rate system and TBT / SPS in agricultural trade. The model reveals that the net trade effect of RMB exchange rate movements relies on the comparison of exchange rate level change (appreciation or depreciation) effect and exchange rate risk effect.

Taking China’s agricultural exports to Japan as a case, this paper makes an empirical examination. A GARCH (1, 1) model is specified to measure the exchange rate volatility and ADL regression with structural break dummy variables is estimated based on the results of unit root test with structural break. The results show RMB depreciation against yen will promote export growth while appreciation hinder export, and exchange rate volatility positively stimulates agricultural exports to Japan. However, the effect of exchange rate volatility on the export is much smaller than that of exchange rate level, which leads to a negative net effect to the export. The policy implications among the empirical results are also discussed.

Introduction

Since the reform of Chinese RMB exchange rate formation mechanism in July 2005, Chinese RMB has been in frequent fluctuations and appreciating gradually. In this context, close attention has been paid to the impact of the RMB exchange rate fluctuations on China's export. Since each industry has its own characteristics, the exchange rate movements may have different effects on different industries. Therefore,as Klein (1990) pointed out, the impact of real exchange rate fluctuations on export trade must be further investigated in the commodity level. In general, compared to manufactured goods, agricultural products have such special industry nature as lower initial cost of investment, the existence of long-term contracts etc.. It is generally acknowledged that the impact of exchange rate movements on agricultural trade is different from that on manufactured goods trade. Gue, Sheldon & McCorriston (2002) has confirmed, compared to other industries, the real exchange rate uncertainty has a more significant negative effect on agricultural trade.

Then as for China, what is the effect of RMB appreciation and associated risks of volatility1 on its agricultural export? A study on this issue has important academic and practical significance. On one hand, there are still no clear-cut theoretical and empirical conclusions on trade effects of exchange rate fluctuations among the economic community. Moreover, the vast majority studies have probed the trade effects of exchange rate fluctuations in developed countries and have neglected the study on those in developing countries like China. Developing countries have the characteristics different from the developed countries, such as the different exchange rate system, lack of a sound foreign exchange forward market, lack of effective financial derivatives, etc., which will impose important constraints on the behaviors of exporters. As for China, there are two important constraints: First, China runs particular foreign exchange management system; Second, China's agricultural exports have encountered serious TBT and SPS. This means the trade effects of exchange rate movements in developing countries should not be overlooked; On the other hand, the current appreciation of RMB will bring certain negative impact on China's agricultural economy and the welfare of farmers (Kong & Li, 2006), while farmers are still the majority of the population in China. Therefore, probing the effect of RMB exchange rate changes on the agricultural export has an extremely important practical significance. Based on the above understanding, this paper, taking China’s agricultural exports to Japan as an case, attempts to explain the impact of RMB exchange rate level changes and volatility on China's agricultural exports.

1 Brief literature review

The study on the impact of exchange rate changes on agricultural trade is launched first by Schuh (1974), which made the fundamental argument that the exchange rate was Exchange rate volatility may be defined as the risk associated with unexpected movements in the exchange rate(McKenzie, 1999).

an omitted significant variable in economic analysis of the U.S. farm sector. After his pioneering research, a considerable amount of researches evaluated quantitatively the impact of nominal and real exchange rate on agricultural trade. Different empirical methods andexchange rate variables were used in these studies, but leading to the consensus:

exchange rate fluctuations have significantly impeded agricultural trade flows, and compared to other sectors, such negative effect is more noticeable.

Some empirical literatures compared the different effects of exchange rate changes

on agricultural sector and other sectors. These studies reached similar conclusions, namely: Overall, the exchange rate changes significantly negatively affected agricultural trade. Susanti (2001) and Mathew, Terry & Agapi (2006) investigated the effects of exchange rate changes on agricultural trade at both sector and product level. Susanti (2001) examined Indonesia’s total exports of agricultural products and five products export and revealed that all of them were significantly negatively affected by Indonesia's exchange rate movements. From the early investigation of Robert & Richard (1981) on American wheat, cotton and soybean to recent investigation of Jose, Kranti & Koo (2006) and Li & Li(2005) on soybean, the researchers investigated the impacts of exchange rate movements of a number of countries on their major

agricultural trade flows including barley, wheat, pork, cotton, coffee, cocoa, living pig, corn etc.. These studies have generally supported the conclusion of the negative impacts of exchange rate movements on disaggregated agricultural trade. However, some studies (such as Anderson & Garcia，1989；Abdulkudos, 2003) indicated that, for a certain agricultural product, the impacts of exchange rate movements vary across countries, and for a certain country, the impacts vary across agricultural products as well. In an era of floating exchange rate system, there are conflicting arguments in theory on if the volatility risk of exchange rate impedes international trade: some models find support for the negative hypothesis yet other models have been derived to support the positive hypothesis. The results of empirical studies which have focused on the exchange volatility are no less confusing but most of them support the negative effects. Sheldon (2003), Gervais, Larue & Olivier (2004) etc. indicated that the risk of exchange rate volatility significantly reduced agricultural trade flow. However, Jin, Gue & Koo (2003) showed that whether the effect of exchange rate volatility is positive or negative is related to the measurement of volatility and the effect of third country as well.

A number of Chinese researchers have made investigations on the influences of

RMB exchange rate changes on China's agricultural trade with focus in two areas. One is to estimate J-curve effect and the exchange rate elasticity of import and export of agriculture-related products, including early studies of Cai (1994), Gu, Li & Zhong (1994) and recent studies of Song (2005) and Zhu, Tian & Wang (2006). The other is to simulate the impact of RMB appreciation on China's agricultural imports and exports within macro models, focusing the influences in different contexts of appreciation. Although the above studies have achieved considerable success, there is still something that should be noticed. First, the theoretical models based on the assumptions of developed countries does not necessarily fit the circumstances of developing countries therefore these models need to be developed based on assumptions of developing countries; Second, close attention should be paid to possible structural break in data generating process (DGP) in order to prevent from "spurious cointegration"; Third, developing countries should receive more concern in future studies. There is still a big difference of the exchange rate system between the developing countries and developed countries, and agricultural exports have played a more important role on developing countries’economic development.

2 Model

This section will construct a model on the basis of Kawai (1981), Fabiosa (2002), Barkoulas & Baum et al (2002), Dekle & Jeong (2006). The impacts of both exchange rate level changes and the risk of exchange rate volatility will be incorporated into the model.

3. Monopolistic competition model

Below we present the basic monopolistic competition model of the exporting firm. Let China be the export country and the foreign country be the import country. A representative household of the foreign country consumes differentiated goods that are arranged on the unit interval, [0, 1]. Among the goods, goods z will be indexed for

1 They used the autoregressive residuals, moving average of the standard deviation, ARCH, GARCH to measure volatility risks of exchange rate, and estimated equations with and without a third country effect.

China’s agricultural product, where 0 < z < n , and goods z* 1 for foreign product, where n < z* <1. Assuming that domestic and foreign goods markets are segmented. The monopolistically competitive firm has the ability to engage in price discrimination by setting a domestic price for domestic sales that differs from the price it sets for exports. Based on the pricing-to-market model of Betts & Devereux (2000), we assume that the exporting firm sells h zt units of output in the home market and exports

4 Empirical estimation

4.1 Empirical specification

To capture the dynamics, following Fang & Lai (2001), the empirical framework is 1 This conclusion is specially related to the model assumptions: both the exported good and imported raw materials are priced in foreign currency. specified as an autoregressive distributed lag (ADL) process combined with a GARCH(1,1) model used for the measurement of exchange rate volatility risks.

(3.19)

Equations (3.17)–(3.19) constitute two-step estimation with generated by (3.18)–(3.19) and then used in (3.17) to estimate its effect on export. As Fang & Miller

(2004) pointed out, the statistical significance and sign of the estimated and coefficients in equation (3.17) provide a simple and straightforward test of the relationship between real export growth and exchange rate depreciation and its volatility.If

, then exchange rate depreciation improves exports. If , exchange rate volatility reduces exports through exporters’responses to perceived risk, while

it stimulates exports. The equation also shows that the net effects relies on the comparison of exchange rate level change effect and exchange rate risk effect.. 4.2 Data sources and processing

This paper employs bilateral agricultural exports from China to Japan on a monthly basis from January 2002 to April 2007. Seasonally adjusted real agricultural export

revenue with base month January 2002 equals nominal export revenue in U.S. dollar deflated by the consumer price index (CPI) of the U.S. and the export price index. CPI comes from the International Financial Statistics and Direction of Trade of the IMF, nominal export revenue and the export price index from the Monthly Statistical Report on China’s Agricultural Import and Export.

The monthly average of bilateral nominal exchange rate, defined as the RMB price of the Japan yen, is calculated based on the bilateral nominal exchange rate of RMB against the U.S. dollar and the Japan yen against the U.S. dollar. The data come from ERS of the United States Department of Agriculture. The exchange rate volatility is calculated by GARCH(1,1) model. Foreign price level equals the CPI of Japan from the Statistics Bureau of the Ministry of International Affairs and Communications of Japan. Foreign demand equals Japan monthly industrial production index from the Euro Stats.

We also calculate the purchasing price index of agricultural material products with base month January 2002 from China's Economic Statistics Bulletin and substitute it for the price index of domestic inputs. The price index for imported inputs is substituted by the world agricultural raw materials index from IFS of the IMF. The number of restrictions in frequency measures is employed for quantifying the

TBT/SPS, on the basis of the number of SPS and TBT in agricultural trade notified to the WTO by Japan.

4.3 Unit root test and parameter Estimation

Non-stationary and unit root tests are conducted to avoid spurious regression. The tests follow two steps: First, all the data of variables are tested using ADF test without structural changes; Second, those non-stationary variables in ADF test will be further tested employing unit root test with structural break contributed by Perron (1989).The results of unit root test indicate that all the variables are stationary except that nominal exchange rate, the price index for domestic inputs and the price index for imported inputs are stationary variables with structural break1. Therefore, we introduce the structural break dummy into the regression equation.

4.4 Findings and further discussion

The results show that both the bilateral nominal exchange rate and its volatility risk are important factors affecting China’s agricultural export to Japan. In general, exchange rate exhibits the expected positive effect, which means that the depreciation of RMB against Yen will increase the export of agricultural products while the appreciation will reduce the export. The significance of nominal exchange rate level with 5 lags indicates the impact of exchange rate changes lasts relative long period of up to five months. This coordinates with the features of a long production cycle and a long period of delivery of the majority agricultural products.

Exchange rate volatility risk, in general, possesses a significantly positive impact on agricultural exports, indicating that exchange rate risk will increase the exports instead of negatively decreasing the export as usually expected. Exchange rate risk variables with 3 lags and 5 lags exhibit significantly positive signs while the variable with 6 lags shows significantly negative sign, which implying that, on one hand,

agricultural exporters might be risk preferred and increase exports when facing the increased exchange rate risk; On the other hand, as DeGrauwe (1988) pointed out that high degree of risk aversive exporters, fearing the drastic decline of export earnings, may increase exports when facing increased risk of the exchange rate, other low degree of risk aversive exporters, however, reduce exports because of lower exports earnings associated with increased risk.

In addition, the above results imply that the exchange rate level changes make a rapid and lasting effect on agricultural exports to Japan, especially a strong impact in a short term, while the exchange rate risk appears to have a strong effect in a longer period instead of a short term. Therefore, in a short term, the effect of exchange rate movements on agricultural export is completely determined by the changes of exchange rate level, but in a relatively longer period, jointly by the changes of both exchange rate level and its volatility risk.

The net effects of exchange rate on agricultural exports depend on the comparison

of the effect of exchange rate level changes and its volatility risks.

Conclusions

This paper attempts to examine the relationship between changes and volatility (risks) of China's RMB exchange rates and its agricultural export. Empirical results indicate that the RMB appreciation after exchange rate formation mechanism reform in July 2005 possesses a significantly negative impact on China’s agricultural exports while the exchange rate volatility risk, in general, possesses a significantly positive impact. However, exchange rate risk effect is much smaller than that of exchange rate level changes, the net effect of exchange rate movements has been dominated by the latter, meaning that RMB appreciation is still a main factor in determining China’s agricultural export to Japan.

Therefore, the negative impact of RMB exchange rate movements on China’s agricultural export should not be underestimated. It is very essential for the government to adjust its policy. Due to the difficulty of exchange rate policy adjustment, the government can start from agricultural policy adjustment to reduce or relieve the negative effect of exchange rate movements. According to the dominant negative effect of RMB appreciation, policy adjustment in short term is to further improve the support system of agricultural export so as to reduce the unit cost of agricultural export. While policy adjustment in long term lies in improving the quality and advancing technology of agricultural products, which will upgrade price competitiveness to quality competitiveness.

In addition, special attention is paid to exchange rate risk. Although this paper finds that the risk of nominal exchange rate volatility positively affects China’s agricultural exports to Japan, the possibility that the majority of small and medium manufacturers are risk aversive and will reduce export in the face of increased risk of exchange rate, can not be excluded because of the use of aggregate data. Thus, the government cannot neglect the stability of foreign exchange market. Meanwhile, providing guidance and financial instruments of foreign exchange for risk aversive exporters is also important to minimize foreign exchange rate risk and maintain stable growth of agricultural export.
