美国对华直接投资对中国技术进步和产业竞争力的影响

20世纪90年代以来美国对华投资发展迅速,投资规模不断扩大,在华子公司引进技术的水平也呈不断提高态势。从美国对华投资的特点来看,其主要集中在技术密集型和资本密集型产业。而且,美国对华投资以市场寻求型为主,研发当地化以适应国内市场的需求就成为其必然选择。本文将在简述美国对华投资企业技术特点的基础上,分析其对中国技术进步以及产业竞争力提升的影响,为中国在引资过程中趋利避害提供理论参考。     

Plastic wastes and the market penetration of auto shredders

In recent years the increased interest in the recycling of plastic wastes has lead to the development of numerous technological approaches to utilizing plastic wastes of varying qualities and types. A major problem with these technologies, however, is the unacceptable contamination levels in the available wastes. This paper examines one area from which relatively uncontaminated plastic wastes can be obtained—shredder residue from automotive shredder operations. In addition to reviewing the historical adoption of shredders, this paper uses econometric approaches to investigate the extent to which the shredder technology has penetrated the market for scrap steel. These approaches suggest that the movement toward shredders and away from the more conventional baler operations that have historically been used to process retired autos is slowing.

A Note on the Theme of Too Many Instruments*

The difference and system generalized method of moments (GMM) estimators are growing in popularity. As implemented in popular software, the estimators easily generate instruments that are numerous and, in system GMM, potentially suspect. A large instrument collection overfits endogenous variables even as it weakens the Hansen test of the instruments’ joint validity. This paper reviews the evidence on the effects of instrument proliferation, and describes and simulates simple ways to control it. It illustrates the dangers by replicating Forbes [American Economic Review (2000) Vol. 90, pp. 869–887] on income inequality and Levine et al. [Journal of Monetary Economics] (2000) Vol. 46, pp. 31–77] on financial sector development. Results in both papers appear driven by previously undetected endogeneity.

Ownership concentration and corporate governance practices: substitution or expropriation effects?

The objective of this study is to analyze the relation between ownership concentration and corporate governance practices of a group of Canadian companies listed on the Toronto Stock Exchange. We rely on the corporate governance index developed by the Report on Business (ROB) in 2002. Our empirical results are consistent with the expropriation effect argument that predicts a negative relation between deviation from the one share‐one vote rule and corporate governance best practices. In this context, the dominant shareholder has incentives to maintain weak internal controls in order to facilitate expropriation. In addition, consistent with prior research, our results give partial support to the substitution effect argument by showing a negative impact of ownership concentration on the board composition subindex.

试析中国证券市场T+1交易制度改革

中国证券市场曾经实行过T+0交易制度,由于存在过度投机T+0被取消,进而推出了T+1交易制度。2010年之后,股指期货等金融衍生产品的推出标志着中国证券改革正走向纵深,T+1交易制度已经不再适应中国资本市场的重大变化,特别是光大“8·16”乌龙事件中,机构利用股指期货和ETF变相T+0交易规避风险,市场的公平与效率亟待维护和提升。为此,本文提出在沪深300成分股中率先实行T+0制度的渐次改革原则及其三大理由。     

层次分析法在出口玩具检验监管风险评估中的应用研究

在对出口玩具检验监管工作研究分析的基础上,选取了具有代表性的指标体系,并引入层次分析法科学地确定各个指标的权重。通过建立层次结构模型、构造判断矩阵、相对权重及合成权重的计算,利用较少的定量信息,将整个考核指标过程数学化。最后,针对进一步完善和改进出口玩具检验监管风险评估工作提出合理化建议。
