“一带一路”框架下的中拉绿色产品贸易:特征、比较优势与出口潜力

在“双循环”背景下,加强“一带一路”建设对中国深化对外开放意义重大,促进中拉绿色贸易符合双方利益,可为“一带一路”延伸至拉美创造新的合作增长点。本文使用2002年至2018年的货物贸易数据,分析了中拉共建“一带一路”过程中中拉绿色产品贸易的特征和趋势,并重点研究了中国绿色产品对拉美的出口潜力。通过使用双边显示性比较优势指数和出口潜力矩阵,文章发现,在现有的中拉货物贸易结构中,绿色产品贸易所占比重较低,贸易对象高度集中,但随着双方经贸合作的全面深化、特别是“一带一路”延伸至拉美,双边绿色产品贸易金额和种类都在稳定上升。尽管中国绿色产品在拉美市场面临着地理距离遥远、市场竞争激烈等客观困难,但中国的优势产品已成功出口到拉美。中国的出口潜力更多地取决于拉美地区的市场需求,一旦拉美对绿色产品的需求提升,那么中国就具备进一步扩大向拉美出口该类产品的潜力。此外,出口潜力矩阵也找出了部分对拉美市场而言具备不可替代性的中国产品,这也将成为中国潜在的对拉出口重点绿色产品。     

The New Comparative Political Economy

With the collapse of communism in the late 1980s the field of comparative political economy has undergone major revision. Socialism is no longer considered the viable alternative to capitalism it once was. We now recognize that the choice is between alternative institutional arrangements of capitalism. Progress in the field of comparative political economy is achieved by examining how different legal, political and social institutions shape economic behavior and impact economic performance. In this paper we survey the new learning in comparative political economy and suggest how this learning should redirect our attention in economic development.JEL classification: B53, O10, O20, P0     

Structural Decomposition Analysis of Physical Flows in the Economy

Many environmental problems can be attributedto the extraction and emissions of physicalsubstances. Increasing our understanding of theeconomic and technological driving forcesbehind these physical flows can contribute tosolving the environmental problems related tothem. The input-output framework is a usefulsetting in which to integrate detailedinformation about economic structure andphysical flows. In this article a specificmethod in input-output analysis is reviewed,namely Structural Decomposition Analysis (SDA).It is based on comparative static analysis,which decomposes historical changes of a policyvariable into determinant effects. SDA has beenapplied, for example, to analyze the demand andtechnological driving forces of energy use,CO₂-emissions and various other pollutantsand resources. This article examines thetheoretical aspects of structuraldecomposition, in particular those concerningphysical flows and environmental issues.Furthermore, the article includes an extensivesurvey of empirical studies.

Evolution of trade patterns in the new EU member states

The paper analyses the evolution of the trade specialization pattern in the new EU member states. Relying on the empirical approach of the Markov transition matrices it analyses both the changes in the external shape of the distribution of comparative advantages and the intra‐distribution dynamics. The new members show a dynamic trade pattern: they gained comparative advantages relatively fast in sectors in which they were lagging behind at the beginning of the transition, notably in some ‘high tech’ products. In addition, many specialization improvements occurred in those items for which world demand expanded at the fastest rate over the nineties.     

论我国劳动密集型产业比较优势和竞争优势的互补性

我国是一个人口大国,劳动力资源丰富是一大优势。发展劳动密集型产业符合我国的比较优势。但是,比较优势并不等于竞争优势。比较优势也可理解为比较生产费用优势,它是由各国土地、劳力、资本等有形资源禀赋上的差别引起的。比较优势强调的是各国不同产业之间的竞争力比较,而竞争优势强调的是各国同一产业之间竞争力的比较。一国产业的比较优势只有通过竞争优势的发挥,才能得到最终体现。一个国家具有比较优势的产业,如果在国际市场上缺乏竞争力,没有一定的竞争优势,就难以实现其比较优势。     

全球化背景下以动态比较优势实现产业技术跨越

全球化背景下中国失去了采用传统保护手段来培育动态比较优势，而面对新的机遇和挑战，中国应立足于自身资源禀赋的比较优势，在某些产业的关键环节选择技术跨越来培育动态比较优势；并通过发展高新技术、加强对传统产业的技术改造和提高技术引进效果来有效实施技术跨越，在一定程度上占据国际分工制高点。     

Pure joint production and international trade: a note

This paper applies the principles of the neo-Ricardian (or Sraffian)theory of international trade to certain joint production systems.It is shown that, in contrast with single-product systems, (i)there is not always a pattern of international specialisation,which would entail the increase of the real wage rate in botheconomies, and (ii) the ‘law of comparative advantage’has no general validity. Furthermore, not only the existenceof such a pattern of specialisation but also the validity ofthis law depend on the values of the variables of distributionof income. The analysis is wholly based on two of the numericalexamples formulated by Bidard in 1997, and further generalisedin an elementary way only when this is considered necessary.     

中国服务出口比较优势与出口结构的变化——基于显示性比较优势指数的实证分析

20世纪80年代以来,中国服务出口有了长足的发展,在全球的位次也大大提升。但是,以改良的显示性比较优势指数为基础的分析表明,中国的服务出口在整体上仍然不具备比较优势。具体观察各个服务部门可以发现,旅游服务的比较优势有较大提高,运输服务从具有比较优势变为不具有比较优势,其他服务虽然处于劣势地位,但这种劣势在不断减弱。从出口结构来看,中国服务出口从80年代的以运输服务为主转变为目前的以旅游服务为主,运输服务的出口比重迅速下降,而旅游服务的出口比重则大幅提高。     

Comparing the impact of management support on police officers’ perceptions of discretionary power and engagement: Australia,USA and Malta

Abstract

This paper uses Social Exchange Theory as a lens for comparing the impact of management support upon police perceptions of discretionary power and employee engagement, across three countries. A survey-based, self-report process collected data from 193 police officers in Australia, 588 from the USA, and 249 from Malta. Structural equation modelling was used to analyse the data. The findings suggest a significantly different management support context across the three countries, as well as significantly different perceptions of discretionary power. Across the three countries, police perceived relatively poor satisfaction with organizational management support and only some engagement levels. However, USA police perceived significantly more discretionary power than the other country samples. These findings provide greater clarity about the link between management support, discretionary power and engagement for the police officers. Since employee engagement likely affects policing outcomes, the findings suggest that poor management support of police officers could negatively affect the provided service. Potential strategies to enhance police engagement include (a) training police managers about how to manage so as to promote greater engagement, and (b) modifying police managers’ performance indicators in line with achieving better police engagement.
