中国高储蓄率问题探究——1992-2003年中国资金流量表的分析

本文以国家统计局公布的1992—2003年中国资金流量表为基础,从收入分配和部门储蓄倾向等两个方面对居民、企业和政府等国内三个部门的储蓄率进行了比较分析。我们发现,尽管居民部门的储蓄率最高,但是,自1992年以来,它实际上呈逐步下降趋势,其主要原因在于居民部门获得的劳动报酬、财产收入和再分配收入均有所下降;企业储蓄率呈现缓缓上升趋势,主要原因并不在于企业盈利能力的提高,而在于其主要支出——对居民部门的劳动报酬支出和利息支出长期被稳定在较低的水平上;政府储蓄率在经历了上个世纪的低位徘徊之后,于2000年以后急剧上升,其主要原因在于,通过初次分配和再分配,政府的可支配收入在国民收入的分配中占据了越来越大的份额,同时政府部门的储蓄倾向也在不断提高。本文的政策建议是:为了实现以提高国内消费率为核心的经济发展战略,我国的经济运行应全面转向以改善收入分配结构、提高居民收入为重点的轨道上。为达此目的,加速财政政策向公共财政转型,增加公共支出和对居民的福利支出,在提高劳动生产率的基础上提高企业对劳动者的支付水平,应成为今后我国宏观调控的长期任务。     

外包与工资差距:基于工业行业数据的实证研究

笔者以Feenstra等人的三要素模型为基础,分析了国际外包影响发达国家及发展中国家熟练劳动力与非熟练劳动力之间工资差距的理论机制,运用我国工业行业面板数据,实证检验了外包对我国工业行业总体及分部门工资差距的影响。结果表明:外包和技术进步对我国工业行业熟练劳动力与非熟练劳动力之间工资差距的扩大均存在明显的正效应,但外包对劳动力资源密集型部门和中等技术部门的影响效应相对更强。     

International Borrowing, Specialization, and Unemployment in a Small Open Economy

The authors show that an increase in international borrowing increases specialization and unemployment in a small open economy that is subject to terms‐of‐trade risks. The economy has a production advantage in the export sector. However, the size of the export sector is limited by the available funds. To insure workers against income fluctuations arising from terms‐of‐trade risks, firms in the export sector offer workers a stable wage rate with the possibility of unemployment. An increase in international borrowing increases specialization in the export sector, which leads to higher unemployment when the terms‐of‐trade shock is bad. A state‐contingent price subsidy can reduce unemployment without inefficiently reducing specialization. The results are robust to the introduction of risk‐averse firms.     

Export Processing Zones, Backward Linkages, and Variable Returns to Scale

This paper investigates the effects of forming export processing zones on factor rewards, national income, and the intermediate-good-producing sector under variable returns to scale (VRS). It is shown that the results obtained in the model under constant returns to scale are substantially modified if VRS is incorporated into the model.     

Artificially Low Interest Rates as Export Promotion Policy

We reconsider the effects of a policy that sets an artificially low interest rate. Such a policy involves a combination of an interest rate ceiling and a rationing rule that assigns a priority‐lending status to export sectors over domestic service sectors. We demonstrate that the policy works as an export‐promotion policy, and improves national income. Furthermore, under some conditions, the policy expands the domestic service sector, despite the reduced amount of funds owing to the rationing rule. Finally, the artificially low interest rate improves national welfare.     

人民币外部实际汇率的产业结构效应*

本文对人民币外部实际汇率的产业结构效应进行了理论和实证分析。理论分析表明,外部实际汇率贬值通过成本效应、支出转移效应直接提升净出口,出口部门需求上升通过产业分工效应、收入效应和城镇化效应间接带动其他部门、其他产业的产出。实证检验显示,外部实际汇率贬值总体上有利于提升工业产出,但外需变化对工业产出的影响要比外部实际汇率显著;外部实际汇率可提升服务业产出但有明显时滞。     

Growth and dynamics of Australia's education exports

Australia is the third largest global exporter of education services and generated $18.6 billion in 2009–2010. The education sector ranks as the top services exports and number three of all export earners in recent years after coal and iron ore. This study analyses the major determinants of Australia's education exports. Using the Johansen cointegration technique, a stable long run relationship is found between education export earnings, real exchange rate, world income and terms of trade. It is also found that policy reforms relating to opening up the education sector from the mid 1980s had a positive growth effect on the sector.     

Outsourcing and the Heckscher–Ohlin Model

The purpose of this paper is to incorporate the currently mushrooming phenomenon of outsourcing into the standard two‐sector, two‐factor Heckscher–Ohlin model of international trade. We first show how outsourcing modifies a firm's production function, and then demonstrate that outsourcing generally raises the return to capital and lowers the real wage, although the nation's GDP rises in proportion to the value‐added in the outsourcing industry. Furthermore, the output of the outsourcing sector may actually fall even though its unit cost goes down; the output of the other sector then rises. By contrast, employment in the outsourcing sector may actually rise.     

Does China really lose from RMB revaluation? Evidence from some export industries

This study attempts to examine the impacts of Real Exchange Rate (RER) misalignment on China's export performance. Using the SUR methodology coupled with disaggregate panel export data, it shows that China's export sector may not necessarily lose from the Central Government's decision to revalue its RMB against the US dollar because the negative impact of the RER appreciation on Chinese exports may be diluted by the positive impacts attributing to a reduction in the RER misalignment.     

Trade Reform and Informal Wages

When trade reform contracts protected formal sectors in developing countries and the formal workers move to the informal sector for employment, does that reduce informal wages? Using a 2 × 2 Heckscher–Ohlin–Samuelson (HOS) structure with formal–informal production organization for the same commodity, we show that a tariff cut in the import‐competing sector increases both informal wage and employment under very reasonable assumptions. An increase in the price of the export commodity will also increase informal wages, although aggregate informal employment unambiguously falls even if the informal export sector is labor intensive. Furthermore, the formal–informal segmentation of each sector opens up an interesting, hitherto unexplored, possibility that the informal export sector may contract despite a price increase in this sector. Change in the overall size of the export sector is also ambiguous and conditional on the relative strengths of changes in these two segments.     

Environmental policy in the two-country-case

Summary The paper analyzes the problem how environmental policy affects sector structure, the allocation of resources, relative price (and comparative advantage) and national income in a two-country case with varying terms of trade. The frame of reference is a two-sector model in which production generates pollutants as a joint product. If a country exports the pollution-intensively produced commodity environmental policy will improve its terms of trade under suitable conditions with respect to demand. Whereas in the political debate the negative effect of environmental policy on the international competiveness of a country is stressed, the terms-of-trade effect gives more leeway to environmental policy. The effects on output, export, imports and the other variables of the system are discussed.Help for calculating the results is acknowledged to J. Eichberger. I acknowledge helpful comments from an anonymous referee. I am also grateful to the Deutsche Forschungsgemeinschaft for financial support.     

Sectoral Income

What is the income of each sector of an economy? E.g., in the case of a country endowed with petroleum resources, what is the income of its petroleum sector? Here we present a definition of sectoral income, which is compatible with an important line of theoretical literature on comprehensive national accounting. We do so first by splitting national income into individual income and then defining sectoral income by considering the contributions to individual income that the sectors give rise to.     

实现服务外包协会的路径研究——以黑龙江为例

中国为金砖四国之首,中国的名字已经令世界瞩目,中国经济不断发展,GDP长期保持在较高的水平,在世界发展进程中,中国已经取得了很大的成就。但是,中国在整体经济发展中商品进出口贸易的比重很大,而服务贸易比重甚小,特别是服务外包业。在这方面,中国与印度相比,相差很大。印度在服务业,特别是服务外包业的发展,占世界整体服务外包业的比例非常大,而且成绩极其显著;而中国服务外包业的发展水平还很低。中国有些省市服务外包业的发展已经有所成就,其中服务外包协会的建设至关重要。黑龙江省通过建立一个良好的服务外包协会,对服务外包业的发展有一个支持,使服务外包业更上一个台阶,创造出良好的业绩,为黑龙江省的经济发展做出贡献。     

外包与生产率:基于工业行业数据的经验研究

本文使用投入产出表的数据计算了我国35个工业行业的外包比率,并以面板数据模型检验了外包对全员劳动生产率的影响;为验证其中的机理,进一步检验了外包对就业以及产出的影响。检验结果表明,当企业把原本自制的但属于其它产业的中间投入品外包出去,将会提高企业的劳动生产率。原因是,外包产生了资本节约型的技术进步;外包在提高劳动生产率的同时,对就业并没有产生负面影响,原因是规模效应抵消了替代效应。正因为这两点,外包对产出的影响可以概括为两个方面:一是促进生产可能性前沿向外移动,是生产边界的推动器;二是导致生产结构从劳动密集型向资本密集型转变,是产品结构升级的转换器。     

Oil Discovery,Political Institutions and Economic Diversification

Diversification is touted as a desirable policy objective for oil‐rich nations because it reduces exposure to volatility. However, the empirical relationship between petroleum and diversification is not well understood. Here, we test the effect of giant oil discoveries on diversification using a panel dataset of 136 countries observed over the period from 1962 to 2012. We notice non‐oil sector export concentration 8 years after a discovery. However, we do not observe any effect on the structure of employment in non‐resource and manufacturing sectors. Democratic political institutions moderate the export and employment concentration effects of petroleum discovery.     

External income shocks and Turkish exports: A sectoral analysis

This study assesses how the growth rates of Turkish trading partners affected Turkish exports in various sectors for the period 1996:01 to 2009:12. To determine this, we modeled the destination countries and the export demand for each sector separately. Each model is estimated as a system of equations, where each equation represents a country using a seemingly unrelated regression method. The empirical evidence suggests that Motor Vehicles, Basic Metals, and Radio–Television are the sectors with the highest income elasticities for most of the analyzed countries, whereas the Food Products and Beverages sector has the lowest income elasticity. We also performed simulations for the effect of a 1% increase in the growth rate of each country on Turkish exports.     

结构式乘数视角下产业投资对经济的影响

为考察产业投资对各产业部门和经济总体的乘数作用,利用里昂惕夫静态投入产出模型和汉森-萨缪尔森模型,在考虑了投资、国民收入和消费之间的相互作用以及产业投资与投资形成额关系的基础上,构建了结构式投资乘数模型,并由此测算了我国17个部门产业投资对各产业部门增加值和国内生产总值的影响.研究结果表明投资取向与经济增长速度无关,但会影响产业结构的变动,其中建筑业、机械设备制造业、批发零售贸易以及住宿和餐饮业的发展易受投资的影响,而在纺织、缝纫及皮革制造业、食品制造业、其他服务业等产业部门的发展中投资的作用则十分有限,这些产业部门的发展要靠消费来拉动.     

有效需求规模假说、研发投入与国家自主创新能力

一国的有效需求规模可用三个基本维度(或要素)和三个补充维度来描述,其中基本要素经济总收入和人均收入的提高,会促进一国研发投入和自主创新能力的提升,而基本要素收入差距的扩大,会降低一国研发投入,并损害其自主创新能力;作为补充要素,进出口规模或开放度的提高对一国研发投入并没有影响,但它可以提升一国研发投入的使用效率和自主创新能力。此外,本文还发现收入差距对一国研发投入和自主创新能力有着十分重要的决定性影响。在一定条件下,收入差距对一国自主创新能力的损害,超过了其他要素的可能影响。     

Toward a Uniform Definition of Household Income

By marrying a "top-down" national income-based approach with a "bottom-up" microdata approach, and a national income accounting perspective with a theoretical perspective, this article attempts to provide a unified framework for aggregating income types to create an income definition that enables researchers to make valid comparisons across nations. An examination of several national household income surveys shows that it is next to impossible to quantify all elements of any new definition in a way that makes international comparisons easy. The framework nonetheless illuminates the differences in current practice and allows researchers to assess the effect of those differences on income distribution measures.     

Outsourcing of accounting tasks and tax management: evidence from a corporate tax rate change

The aim of this article is to investigate if small firms react to a national corporate tax rate reduction by managing their taxable income. In contrast to previous studies, we also analyse whether outsourcing of accounting tasks affects the magnitude of the reaction. Based on a sample of Finnish firms and measures of earnings management, evidence is provided that firms with an internalized accounting function are more active tax planners in this context. This study suggests that outsourcing of accounting tasks increases the corporate tax reporting quality.
