The measurement of intra-industry trade between unequal partners

Summary This note argues that the inadequacy of the GL index to correctly reflect the level of intra-industry trade in presence of trade imbalances may partly be due to measuring intra-industry trade between countries with large differences in economic size. Several adjustment procedures have been suggested in the literature but it is demonstrated that none of the alternative measures seem capable of eliminating the problem. A new measure of intra-industry trade is proposed in which the bilateral level of intra-industry trade is divided by the total number of products traded between two countries to yield an average level of intra-industry trade per product. This measure may also be applied at industry level, and in contrast to the GL index, it is highly correlated with the actual level of intra-industry trade. In studies of intra-industry trade, one should cautiously interpret the GL index since it may give a false picture of the extent and the volume of intra-industry trade. If the standard GL index is used, it is suggested that also alternative measures of intra-industry trade are employed to complement the GL index in order to correctly observe the true extent of intra-industry trade.

日本对华直接投资与中日垂直型产业内贸易实证研究

利用产业内贸易指数对1988至2009年中日贸易数据的分析结果显示:产业内贸易已成为两国贸易的重要组成部分,其中SITC 7类机电产品产业内贸易特征尤为明显。进一步分析表明,中日产业内贸易比重的提升主要得益于垂直型产业内贸易的发展。利用Fukao等人(2003)的模型对FDI与垂直型产业内贸易的分析结果表明,在FDI成本与贸易成本较低的条件下,当两国存在要素禀赋差异时,FDI会引起两国间垂直型产业内贸易。     

Recent evidence on determinants of intra-industry trade

Recent Evidence on Determinants of Intra-Industry Trade. — This paper provides recent evidence on determinants of intra-industry trade for the United States. Results do not support the role of scale economies in explaining intra-industry trade. Product differentiation and degree of standardization, categorical aggregation, non-tariff barriers, and international transportation costs are important determinants of intra-industry trade. The overall explanatory power of the estimated model is shown to increase over time, stressing the importance of using recent trade flow data to test propositions concerning determinants of intra-industry trade.     

Tests of the empirical classification of horizontal and vertical intra-industry trade

Tests of the Empirical Classification of Horizontal and Vertical IntraIndustry Trade. — Using longitudinal data this paper shows the separation of international trade in (a) inter-industry trade, (b) horizontal intra-industry trade, and (c) vertical intra-industry trade used in the empirical trade literature to be non-stable at the individual product level. The high level of vertical intra-industry trade mentioned in the empirical literature probably covers up many products shifting between e.g. vertical and horizontal intra-industry trade. The paper therefore questions the work of the last decade in the measurement of intra-industry trade.

Chinese Bilateral Intra-Industry Trade: A Panel Data Study for 50 Countries in the 1992–2001 Period

This study examines the features and determinants of Chinese intra-industry trade during the 1992–2001 transition period for 50 of China’s trade partners. We disentangle total intra-industry trade (TIIT) into vertical intra-industry trade (VIIT) vis-à-vis horizontal intra-industry trade (HIIT), using data at the four-digit SITC level. The findings indicate that Chinese bilateral intra-industry trade, particularly VIIT, increased significantly during this transition period. VIIT appears to be positively related to differences in consumer patterns. HIIT is negatively related to these differences. In addition, we find that FDI has played an important role in determining IIT, especially VIIT. Other significant intra-industry trade drivers are geographical distance, economic size, trade openness and trade composition. Finally, the impact of China’s liberalization policies and the special role of Hong Kong are demonstrated. We discuss a number of important business and political implications that can be drawn from our findings. JEL no. F14     

A review of trade trends: South Africa and the Indian Ocean Rim

Since 1990, intense diplomatic efforts have taken place to secure and negotiate trade treaties with South Africa's traditional trading partners (the European Union, in particular) and those countries in close geographic proximity. This article examines South Africa's trade links with some of its ‘non‐traditional’ trading partners, in particular the countries of the Indian Ocean Rim (IOR), in an attempt to ascertain the nature of the trade and its importance vis‐a‐vis the rest of the world. An examination of trade data for the years 1992‐5 indicates that trade with the IOR consists mainly of the mutual exchange of natural resource products and that this trade is growing much faster than South Africa ‘s trade in general. Given this trade dynamism, South Africa should pay increasing attention to international relations with these countries. South African trade with the Rim was also found to differ from trade with the rest of the world in that it comprises the mutual exchange of natural resource‐based products. This research shows that our imports and exports are positively related to the gross domestic product of our trading partners, and negatively related to their population size and distance from South Africa. Also, more open economies have absorbed more exports from South Africa. There is some ambiguity as to the role that distance plays in determining the level of imports into this country. The intensity indices computed in this article have to be viewed in the light of this research.     

Does the measurement of intra-industry trade matter?

Does the Measurement of Intra-Industry Trade Matter? — This paper discusses different methods of capturing the main aspects of the Chamberlin-Heckscher-Ohlin-Samuelson model. Of particular interest are the distinction between horizontal and vertical intra-industry trade, the adjustment of aggregation biases, and the definition of inter- and intra-industry specialization at product level. The main findings are that it is important to disentangle horizontal and vertical intra-industry trade, and to consider specialization patterns within refined product groups. Moreover, there is a nonlinear relationship between intra-industry trade and economies of scale that may explain contradictory results in the literature.

International intra-industry trade of China

International Intra-Industry Trade of China. — The purpose of this paper is to measure the extent of the international intra-industry trade of China, and to test empirically various country-specific and industry-specific hypotheses concerning the determinants of vertical and horizonal intra-industry trade between China and her major trading partners. It is revealed that China has possessed the prerequisite of intra-industry trade and that China’s intra-industry trade follows similar patterns of those in developed countries as China is moving towards a market-oriented economy.

THE RELATIONSHIP BETWEEN TOURISM AND TRADE IN SOUTH AFRICA

This article explores the relationship between tourist arrivals and trade in South Africa. Two analyses were conducted – a panel data analysis, which included tourism and trade data of 40 countries with South Africa, and a time‐series analysis that involved South Africa's main tourism and trade partners. Cointegration tests, Granger causality and Block exogeneity tests were used to investigate the nature of the relationship. The results of the panel data analysis show that for South Africa as a whole, there is indeed a long‐term relationship between tourist arrivals and trade, and that bidirectional causality exists. The results for the country case studies are mixed, although the evidence is stronger for the hypothesis that tourism causes trade.     

中国制造业国际分工地位研究——基于产业内贸易形态的跨国比较

利用四分位贸易数据,从产业内贸易形态跨国比较的视角,本文对中国制造业国际分工地位进行了研究。结论发现:中国贸易50%以上为低品质垂直产业内贸易,发达国家50%以下为低品质垂直产业内贸易;随着产品技术含量升级,中国低品质垂直产业内贸易比重上升,高技术产品达92.6%;劳动密集型行业以水平产业内贸易为主,技术和资本密集型行业以低品质垂直产业内贸易为主。因此,中国制造业国际分工地位低下,在技术和资本密集型产品上尤为低下。提升"中国制造"国际分工地位,实现"中国制造"到"中国创造"成为当务之急。     

Can trade liberalisation in South Africa reduce poverty and inequality while boosting economic growth? Macro–micro reflections

South Africa is trapped in a cycle of modest growth, unacceptable poverty levels and record unemployment. This has led to renewed interest on the relationship between macro (growth) and micro (poverty and distribution) issues. This paper uses a macro–micro tool that couples a computable general equilibrium model with microsimulation models to examine the impact of further unilateral trade policy reforms on growth, poverty and welfare. Trade liberalisation alone has very minimal short-run macroeconomic consequences while its long-term impacts are positive and magnified by technical factor productivity (TFP) effects. Trade liberalisation has no appreciable impact on poverty in the short run even if we allow for trade-induced TFP increases. In the long run, however, poverty reduces even in the case when we do not allow for TFP increases. Trade liberalisation policy has been found to be progressive despite the low level of tariff protection remaining in South Africa.     

中国金融服务业贸易模式和影响因素——基于1999～2009年数据的实证研究

本文以静态G—L指数和动态MIIT指数测算了金融服务业产业内贸易水平,然后基于1999~2009年数据,建立计量模型,对影响因素进行了实证分析,包括人均收入水平、金融市场规模、对外直接投资和货物贸易。结果表明人均收入和市场规模与金融服务产业内贸易水平正相关,而FDI和货物贸易的影响与理论预期不一致,对此文中给出了解释分析。本文克服了以往研究在模型设定、因素选取和度量中存在的几点不足,最后给出了几点建议。     

On the Measurement of Product Quality in Intra-Industry Trade

The world has witnessed a dramatic increase in trade over the last forty years. Much of this growth in trade is intra-industry in nature. A relatively recent development in the intra-industry trade (IIT) literature is the measurement of the simultaneous import and export of quality-differentiated products, commonly known as vertical and horizontal IIT. In this paper we compare the Greenaway, Hine and Milner (1994) and Fontagné and Freudenberg (1997) approaches to disentangling vertical and horizontal intra-industry trade and examine some of the implications of employing simple ratios to define the boundary between product quality types. We present a complementary approach based on the traditional Grubel and Lloyd (GL) index and demonstrate with numerical examples its versatility and applicability at the product level. JEL no. F19
