财政分权、经济增长与外贸依存度——基于1978～2007年改革开放30年数据的实证分析

本文以我国1978～2007年的数据,运用协整、Granger因果检验、脉冲响应函数研究了我国财政分权、经济增长对外贸依存度的动态影响。研究发现:长期内,财政分权会推进外贸依存度的提高,而短期内财政分权对外贸依存度的作用不显著;以人均GDP衡量的经济增长,在短期内可提高外贸依存度水平,而在长期中却会降低外贸依存度。分析表明,财政分权引致的地方政府为经济增长而产生的对FDI和出口的激励,以及贸易升级、产业结构调整、内需导向型经济增长模式,是财政分权、经济增长和外贸依存度之间动态关系产生的内在逻辑。     

Re‐Visiting Financial Development and Economic Growth Nexus: The Role of Capitalization in Bangladesh

This paper revisits the relationship between financial development and economic growth in Bangladesh by incorporating trade openness in production function using quarter frequency data over the period of 1976‐2012. We applied combined Bayer–Hanck cointegration approach to examine cointegration among the series. Our empirical evidence suggests that development of financial sector facilitates economic growth but capitalization impedes it. In addition, trade openness stimulates economic growth. Labour is also positively linked to economic growth. The vector error correction model Granger causality results divulge that financial development causes real per capita gross domestic product (GDP) growth, and resultantly, real per capita GDP growth causes financial development in a Granger sense. The results also show that trade and labour Granger cause economic growth. The findings of the paper provide insights for policymakers to use financial development and trade openness as a tool for sustained economic growth in the long run. The paper also suggests policymakers to utilise capitalization in a way that is beneficial for economic growth of Bangladesh.     

How dependent is the Chinese economy on exports and in what sense has its growth been export-led?

This paper studies the interaction between foreign trade and domestic demand and supply in China's economic transformation. It compares China's export dependency with other economies using input–output analysis. The paper also conducts econometric analysis of provincial level data to examine causality between the growth of foreign trade and components of domestic demand, and causality between the growth of foreign trade and total factor productivity. The main message is that China's export dependency is significantly lower than implied by the headline exports-to-GDP ratio. Moreover, the contribution of export to economic growth in China came mainly from its impact on total factor productivity growth from a supply perspective rather than its multiplier effect from a demand perspective. This relationship was found to be stronger in the more developed coastal areas than in the less developed inland areas.     

The trade-growth nexus in the developing countries: a quantile regression approach

This paper applies quantile regression techniques to investigate how the impact of trade openness on the growth rate of per capita income varies with the conditional distribution of growth. Using formal robustness analyses, we first identify robust variables affecting economic growth (investment, government balance, terms of trade, inflation, and population growth) which we then use as controls in the quantile regression estimations. Our findings suggest a heterogeneous trade-growth nexus: for both the short and the long run, the effect of openness on growth is higher in countries with low growth rates compared to those with high growth rates.     

Economic effects of trade patterns on productivity: Evidence from the Korean automobile industry

Among inter-firm trade patterns, the cooperative trade system has proved to be superior to arms-length or market-oriented trade in the long run. Within the cooperative trade system, the transition from dedicated (single supplier) trade to network trade is proving a remarkable phenomenon. In our theoretical model, we compare the relative economic efficiencies between dedicated and network trade systems. Then in empirical analysis, we examine the relationship between alternative trade patterns and the productivity of the automobile industry. The main results of the theoretical model show that network trade results in a higher profit level than dedicated trade as a rule, although network trade is less stable than dedicated trade. Empirical study reveals that increasing network trade leads to higher productivity.     

Impacts of China-US trade conflicts on the energy sector

This paper uses a multi-country input-output model to simulate the impacts of the recent China-U.S. trade war. We first examine in detail the list of products subject to additional tariffs, and then use the model to estimate the economic impacts of the trade conflict. Based on the direct and indirect impacts on the energy sector of each country, we then extend the analysis to the issue of global energy demand. Our empirical results indicate that both China and the U.S. suffer from the conflict, although the impacts on China are greater Both countries experience a reduction in energy demand and a general economic slowdown. Although certain countries may benefit from the China-U.S. trade conflict in short-run, a general negative impact on the global economic prospects can affect all. Moreover, a short-term marginal impact on the global energy market is found, but as the consequence of long-term uncertainties and indirect economic impacts, further reductions of global energy demand are expected.     

FDI、对外贸易对中部经济增长影响的实证分析

本文利用中部地区1993年至2007年年度样本数据,应用协整理论及格兰杰因果关系检验等现代计量经济学方法,定量分析了FDI、对外贸易和经济增长之间的动态关系。结果表明,中部地区经济增长在短期内与对外贸易互为Granger原因,而外商直接投资在短期内与中部经济增长不构成Granger因果关系;经济增长对对外贸易的波动冲击表现出较大的正向效应,而FDI由于地区因素的影响,作用较小,同时方差分解也表明对外贸易在中部经济增长预测误差的方差贡献度中所占比重最大。     

自由贸易抑或贸易保护——国际贸易的经济增长效应再考察

全球经济复苏过程中,发达国家与新兴经济体之间关于自由贸易的争议也变得空前激烈。国际贸易是否有利于全球经济增长?这实际上是长期以来国际经济学与发展经济学领域颇具争议的问题之一,而在当下对这一问题进行重新审视更具有重要的现实意义。传统贸易理论对贸易合理性的探究尽管触及了经济增长问题,但在贸易静态收益理论的框架下,国际贸易究竟是否会促进一国经济增长,既取决于各个国家在各个发展阶段的经济增长究竟偏向于出口部门还是进口部门,也取决于各种贸易政策对各个部门的相对供给和相对需求的影响。本文对现有针对国际贸易与经济增长关系所做的实证研究作了系统回顾和分析总结,明确指出了目前各种看似矛盾的实证证据背后的理论和技术根源。在此基础上,运用两阶段最小二乘估计(2SLS)和GMM动态面板回归技术,对1960～2006年期间全球各国面板数据进行分析,对不同收入水平的国家组别分别就其贸易占GDP比重与GDP增长之间的关系进行实证检验。文章发现,上述实证研究证明国际贸易对经济增长的促进作用与一国经济发展阶段相关,但对不同收入水平的国家而言则存在差异,同时进口和出口在经济增长中的表现也存在差异性。总体来看,对中等收入国家而言,贸易占GDP比重与GDP增速之间的关系最强,进出口均有较强带动作用;高收入国家贸易占GDP比重与GDP增速之间关系较弱,进口的作用甚至大于出口;低收入国家贸易占GDP比重与GDP增速之间的关系最弱,进口甚至有抑制作用。     

Exports,imports and growth: New evidence on Italy: 1863–2004

The nexus between trade and economic growth in Italy has been widely debated by historiography. However, there are no long run analyses on this topic that cover the whole span from Unification to present days. This paper contributes to fill this gap by investigating the relationship between real exports, imports and GDP in Italy from 1863 to 2004 by using cointegration analysis and causality tests. The outcome suggests that these variables comove in the long run but the direction of causality varies across time. In the period prior to the First World War import growth led GDP growth that in turn led export growth. Conversely, in the post-Second World War period we have a strong bidirectionality between imports and exports consequent on the increase in intra-industry trade. We also find a weak support for export-led growth and growth-led imports. This suggests that exports were not the only or the main driver of economic growth. There was probably a multiplicity of factors at work, among which high rates of capital formation and the expansion of internal demand probably stood out.     

上合组织自贸区经济效应的前瞻性研究--基于GTAP模型的模拟

文章在分析中国同上海合作组织成员国贸易现状的基础上,运用GTAP模型实证研究了建立上合组织自贸区可能带来的经济影响。研究发现建立自贸区虽然在短期内可能存在一定的困难和冲突,但是符合各成员国的长远利益。具体结论如下:从短期来看,大部分成员国贸易放大效应较为明显;各成员国会扩大对比较优势产品的出口,增加对比较劣势产品的进口;各成员国贸易条件和福利水平变化不一,一些小国和落后国家贸易条件恶化,福利水平下降。从长期来看,自贸区的建立能有效拉动各成员国经济增长;随着区域内分工纵深发展,各国产业结构均出现调整。总体来说,完全自由贸易情形下的经济效应要大于设置关税减让例外情形。     

An aggregate import demand function for greece

This study estimates the aggregate import demand function for Greece using annual data for the period 1951–92. There are two methodological novelties in this paper. The authors find that the variables used in the aggregate import demand function are not stationary but are cointegrated. Thus, a long-run equilibrium relationship exists among these variables during the period under study. The price elasticity is found to be close to unity in the long run. The cross-price elasticity is also found to be close to unity. Import demand is found to be highly income elastic in the long run. This implies that with economic growth, ceteris paribus, the trade deficit for Greece is likely to get worse.     

Does China Transfer Productivity Enhancing Technology to Sub‐Saharan Africa? Evidence from Manufacturing Firms*

Abstract: This paper considers whether trade between China and sub‐Saharan Africa results in productivity‐enhancing technology transfers to sub‐Saharan African manufacturing firms. As trade flows between countries potentially results in interactions that lead to technological improvements in the production of goods and services, we parameterize the level of total factor productivity for African manufacturing firms as a function of foreign direct investment flow, and for the country in which it operates, trade openness with China, and its interaction with foreign direct investment. With micro‐level data on manufacturing firms in five sub‐Saharan African countries, we estimate the parameters of firm‐level production functions between 1992 and 2004. Our parameter estimates reveal that across the firms and countries in our sample, there is no relationship between productivity‐enhancing foreign direct investment and trade with China. In addition, increasing trade openness with China has no effect on the growth rate of total factor productivity. To the extent that total factor productivity and its growth is a crucial determinant of economic growth and living standards in the long run, our results suggest that increasing trade openness with China is not a long‐run source of higher living standards for sub‐Saharan Africa.

原产地规则的经济效应研究

原产地规则是国际贸易中的核心规则之一,深刻地影响着国际贸易的发展。本文通过使用经典的包络方法对原产地规则的经济效应进行了深入分析,将原产地规则的经济效应具体分为"最终产品产量减少效应"、"中间投入品强制增加效应"以及"中间投入品替代效应"三种子效应。然后,在模型分析的基础上,以我国汽车零部件的原产地规则为例对三种子效应进行了具体分析。最后得出结论,原产地规则的核心在于提高中间投入品的本地化含量。一方面由于"最终产品产量减少效应",最终产品总产量趋于减少;另一方面,原产地规则通过"中间投入品强制增加效应"和"中间投入品替代效应"对中间投入品行业产生影响。     

东亚与欧盟区域的产品需求结构与贸易模式

东亚和欧盟分别表现为外需主导型和内需主导型的贸易模式。两种不同的贸易模式对经济发展产生着不同的影响。由于东亚区域对外部最终产品市场的严重依赖,所以,后危机时代下,东亚贸易模式转型的必要性更加明显。但是,东亚贸易模式的转型将是一个长期的过程,而中国将在这个过程中发挥重要的作用。     

Impact of financial development on domestic investment: Evidence from West African countries

This paper investigates the effect of financial development on domestic investment in West African countries. The study uses data from 1985 to 2019 and employs the pooled mean group technique. The main finding of the study is that financial development has a positive effect on domestic investment in the long run but an insignificant effect in the short run. Furthermore, remittances, real GDP per capita and trade openness increase investment rate. The results of causality tests support the view that investment is a channel through which financial development stimulates economic growth. Therefore, it is reasonable for the selected countries to formulate policies that promote domestic credit to the private sector in order to ease liquidity constraints and increase investment and economic growth.     

Potential demand and external trade

Summary Both in theoretical and empirical studies of international trade relative prices play a dominant role. Standard international trade theory asserts that under certain conditions the price mechanism may lead to an equilibrium between demand for and supply of goods from and to different countries. For short periods, some relevant conditions may not be fulfilled; in that case other adjustments such as changes in non price conditions may equate demand and supply or, alternatively, disequilibria may exist. Direct statistical evidence on non price conditions, excess demand and excess supply is scarce.This paper describes a partly indirect approach of the not price conditioned trade fluctuations. The basic model assumes that these fluctuations are largely dependent on pressure of demand, which is defined as the tension between potential demand and potential supply. In this way both exports and imports are divided in a potential component, dependent on relative prices, and a pressure induced component. The other main assumption is that actual domestic demand changes according to the demand function. Combining these relations, potential demand for domestic products is the sum of domestic demand and potential export demand minus potential import demand. Potential supply is assumed to be a constant fraction of the exogeneously given production capacity.The model is used for an iterative approximation of the changes in potential demand and pressure of demand for the Netherlands. For this purpose estimations for actual exports and actual imports of commodities are derived from the model. In the initial estimations, potential demand is approximated by means of actual demand, during consecutive rounds the results of the preceding stages are used. After three rounds the coefficients are stable. The values calculated for the yearly changes in potential demand are for most years in concordance with a priori expectations. For the reference period, the explanatory power of the computed pressure of demand is either of about the same quality as that of conventional pressure variables or better.

Reputation and learning: Japanese car exports to the United States

This paper incorporates learning and reputation building into a simple dynamic stochastic model with asymmetric information. We use the model to study a bilateral trade flow influenced significantly by learning and reputation, namely U.S. imports of Japanese cars over the period 1961–2004. Numerical simulations replicate the trade flow in a robust fashion. Including the Voluntary Export Restraint in our simulations predicts U.S. imports decreased by 2.46 million cars over the years 1981–1984. Since learning and reputation building require time, predicted short run trade patterns can be quite different than those predicted in the long run. We apply this idea to understand the change in Japanese market share in the U.S. automobile market. We also explore the importance of sectorial differences in the speed of learning and reputation building on predicted trade patterns. Lastly, we examine how the extent of asymmetric information existing between importers and exporters changes under different trade policies.     

Estimating Chinese Trade Relationships with the Silk Road Countries

In this paper we discuss the extent to which countries in the former Silk Road regions are either reaching or failing to reach their trading potential with China. We estimate a gravity model of trade using a Poisson pseudo‐maximum likelihood estimator, and estimate trade potential using in‐sample, out‐of‐sample and counterfactual approaches. We compare trade potential using these three methods for Silk Road country trades with China. Next, we compare the estimated trade potential to actual trade, and find that most Silk Road countries are underperforming in their trade with China. However, trade performance against potential improved for most countries over the years 1990–2013. Our results suggest that China's former Silk Road trading partners have yet to realize the full potential benefits of China's economic growth but that the gap may be narrowing.
