产品内分工理论的历史沿承及共范式嬗变

产品内分工理论是近期国际贸易分工理论中的研究前沿。该理论虽然最近才被国际贸易学界关注,但是与其相似的理论形成已久。本文在综述产品内分工理论历史沿承的基础上,探究该理论的范式嬗变。     

省级以下土地垂直管理及实施难度研究

阐述土地管理机构垂直管理是满足现阶段市场经济要求的有效管理体制，符合当前行政管理体制改革中垂直管理渐强的趋势。实行机构垂直领导体制是统一当前国土资源管理的基本要求，是当前市场经济阶段处理中央与地方关系，加强中央宏观调控能力和防范经济风险的必然选择。新形势下的垂直管理在实施之初转变领导意识，正确处理国土资源管理部门与地方政府的关系，重视自身的权力监督与约束制度建设。     

Literacy,technology and ‘technological literacy’

The shortcomings of the technological literacy metaphor are reviewed. The lack of an agreed meaning for this concept reflects a widespread perplexity about how the study of technology should be incorporated into general education. The paper considers how the study of literature and history might contribute to an understanding of technology and posits a framework which permits the study of the made world to be incorporated within a humanistic educational scheme. It is suggested that the historical study of technologies of literacy could play a significant role in curricular integration.Based on a Plenary Address to the second Domains of Literacy Conference:Literacies for a Productive Future Institute of Education London 1/9/94Michael Barnett has been, since 1992, Professor of Technology and Education at the Institute of Education in London University. Prior to that he was Reader in Physics at Imperial College London. His main scholarly activities are concerned with the history, philosophy and sociology of technology and their bearing on educational practice. He has established an MA programme in Technology and Education which reflects these concerns.     

Vertical Restraints and Market Access

This paper analyzes vertical restraints in relation to market access issues. In Section II we briefly review the recent three major trade conflicts between Japan and the USA in light of vertical restraints. In Section III we review the major policy lessons of the economics literature of vertical restraints, and analyze whether we need a special treatment for vertical restraints abroad for a market access reason. In Section IV we evaluate the policy options towards foreign foreclosure and suggest that nondiscriminatory application of foreign or home competition policy should be the mechanism to address such concern instead of trade policy actions such as voluntary import expansions.     

审计市场中的合并、产业专用化投资和价格竞争

本文从产业组织的角度，分析了审计市场的合并、产业专用化和价格竞争等竞争行为，并进一步探讨了这些行为对审计质量和社会福利的影响。本文认为，审计质量的信号传递机制推动了产业中的合并行为，而审计产业的专用化投资行为在于策略性地阻止进入。由于审计产品的异质性、信任品特性以及强大的买方谈判能力使得审计市场存在激烈的价格竞争，而合并和产业专用化投资有助于事务所降低成本。因而，审计市场的竞争提高了社会福利。     

On the Merits of Vertical Divestiture

This paper demonstrates that vertical divestiture may increase consumer welfare even when the divestiture eliminates substantial scope economies and precludes only limited sabotage. More generally, the merits of vertical divestiture are shown to vary with: (1) the type and the intensity of competition in the retail market; (2) the locus of scope economies under vertical integration; and (3) the relative social values of consumers’ surplus and profit.     

Testing for Vertical Fiscal Externalities

The purpose of this paper is to design a test of whether the vertical external effects associated with tax base sharing among local and regional governments have become internalized via the intergovernmental transfer system. Such tests are important in the sense that the income tax rates chosen by different levels of government will generally be correlated, even if the resource allocation is optimal from society's point of view. By using panel data for the Swedish local and regional public sectors, the results imply that an increase in the regional income tax rate induces the municipalities in the region to decrease their income tax rates. In addition, we are able to reject the null hypothesis that the vertical external effects have become internalized.     

An Analysis of Trade Patterns and the Effects of the Real Exchange Rate Movements in East Asia

This article investigates the patterns of vertical specialization in trade among China, Japan and Korea, and the effects of real exchange rate fluctuations under a multistage production process. By extending the models of Yi (2003, 2010), we derive two distinct features of vertical specialization and test them using Time-Varying Parameter (TVP) VAR. We find that a positive shock to China’s final good consumption increases the intermediate goods trade between Korea and China, with expanding magnitude over time. In addition, the positive effect of a real exchange rate depreciation on intermediate goods trade is strengthened through the competitiveness-enhancing channel, with this effect being more pronouncing in Korea-China trade than in Korea-Japan trade.     

Export Sophistication: A Dynamic Panel Data Approach

In this article, we analyze export sophistication based on a large panel dataset (2001–2015; 101 countries) and using various estimation algorithms. Using Monte Carlo simulations, we evaluate the bias properties of estimators and show that GMM-type estimators outperform instrumental-variable and fixed-effects estimators. Based on our analysis we document that GDP per capita and the size of the economy exhibit significant and positive effects on export sophistication; weak institutional quality exhibits negative effect. We also show that export sophistication is path-dependent and stable even during a major economic crisis, which is especially important for emerging and developing economies.     

财政压力、技术创新与绿色全要素生产率

经济社会转型期典型的中国式"压力型"财政，对地方创新活动和绿色可持续发展具有重要影响。运用2004~2017年中国256个地级市面板数据，实证考察了财政压力对绿色全要素生产率的影响以及传导机制。基准检验结果显示，财政压力显著抑制了绿色全要素生产率的提升，技术创新对绿色全要素生产率具有显著的促进作用；中介效应检验发现，财政压力通过抑制技术创新进而阻碍绿色全要素生产率的提升，即验证了财政压力→技术创新→绿色全要素生产率的传导机制；进一步门槛效应检验表明，技术创新对绿色全要素生产率的影响存在基于财政压力的双门槛效应，在财政压力的不同门槛值区间，技术创新对绿色全要素生产率的促进效应呈现出明显的阶梯性降低趋势。未来需综合完善中国式"压力型"财政激励制度，合理控制财政压力的区间范围，助力技术创新以提升城市绿色全要素生产率。
