能源回弹效应下高碳产业低碳转型过程中的技术突变性

考虑能源回弹效应下,分析高碳产业低碳技术突变技术门槛,发现技术碳减排存在由量变到质变的门槛效应,另外还发现能源回弹对门槛效应具有显著影响。运用Hansen门限面板模型、结合CD生产函数的能源回弹模型发现：①不考虑能源回弹效应,高碳产业低碳化过程中的技术突变存在两个门槛;②考虑能源回弹作用,将减少为一个门槛,并且将延长高碳产业完成低碳技术突变所需时间。因此,为加快高碳产业低碳技术突变,有效减少碳排放,一方面应缓解能源回弹效应的影响,对能源回弹效应较大的高碳产业采取实时监控,对能源回弹较小的高碳产业采取定期检查和不定期抽检方式监控;货币政策、财政政策和产业政策相互配合,在高碳产业拉动经济增长的同时,最大限度控制能源回弹效应。另一方面,市场手段和政府职能双管齐下,协助企业低碳技术升级和设备改造,优化税收结构,弥补低碳技术升级导致的负外部性,完善高碳产业转移或市场退出机制。

加工贸易出口与反倾销的动态关系

在描述我国加工贸易出口和国外对华反倾销现状的基础上,运用协整理论、建立误差修正模型和进行Granger因果关系检验分析加工贸易与反倾销之间的因果关系,然后建立VAR模型、进行脉冲响应分析和构建方差分解模型进一步研究了两者的动态变化关系。结果表明:反倾销对我国加工贸易出口具有显著的负向影响,并且该影响随着时间的推移而逐渐增强;加工贸易出口对反倾销的影响并不十分明显,但从长期看,加工贸易出口增长同样会加剧国外对华反倾销。

How Big Was the Effect of Budget Consolidation on the Australian Economy in the 1990s?

This article evaluates the effects of budget consolidation on the Australian economy in the 1990s. As the economy recovered from the 1991–92 recession, the need to improve the fiscal balance to lift national saving became the dominant influence on fiscal policy. The article argues that spending cuts by the Australian federal government announced in 1996 had immediate effects on financial markets, with reduced long‐term interest rates of about 50 basis points in 1996–97. Using a modified version of the Treasury macroeconometric model of the Australian economy (TRYM), the article simulates the net macroeconomic effects of the expenditure cuts, fiscal consolidation and lower long‐term interest rates. The article finds that the program of budget consolidation had a sizeable short‐ and medium‐term impact on the economy, raising Gross Domestic Product by up to three‐quarters of a percentage point and reducing unemployment by 0.3 percentage points over the next two to three years.     

日本政府的纳米科技发展战略与重大举措

日本政府自1980年初即开始对纳米技术进行战略性支持,抢占纳米技术制高点.2000年以来更将纳米技术与材料作为重点领域纳入其国家科技发展基本计划,推行一系列促进纳米技术研究开发与产业化的重大举措,使日本在此领域保持世界领先水平: (1)建立最高决策、项层设计与综合协调的体制; (2)加大投入; (3)实施各类计划与项目;(4)产学官合作创造新产业等.     

国内外嵌入性研究述评

对现有国内外嵌入性研究进行了评述。指出:目前嵌入性的概念内涵已较为成熟;一些学者综合社会资本和社会网络研究,对嵌入型的概念构成提出了不同的维度划分方式,多数学者从不同侧面探讨了嵌入性与企业活动的关系;现有研究的不足主要体现为,不同层面的研究没有有效交融、嵌入性与企业活动间联系研究的系统性有待开发、一些社会网络研究方法等无法被充分应用于此方面的研究中。

The Relation Among Targets' R&D Activities, Acquirers' Returns, and In-Process R&D in the US

Abstract:  Using a sample of 129 mergers and acquisitions (M&As) in the US between publicly traded acquirers and targets in research and development (R&D) intensive industries over the period of 1994-2004 and a size- and industry-matched sample, we examine the relation among targets' R&D activities, the probability of acquirers' writing-off in-process R&D (IPRD), and acquirers' returns around the time of M&A announcements. We find that firms acquiring targets with higher R&D investments tend to write off some of the acquired R&D assets upon the completion of the M&As. We also find that the median cumulative abnormal return during the three days around M&A announcements for acquirers with subsequent IPRD write-offs is −2.73% while the return for acquirers without IPRD write-offs is −0.60%. This suggests that acquirers' stock returns around M&A announcements are much lower when investors expect acquirers to expense IPRD. The results are consistent with our conjecture that acquirers tend to write-off IPRD when they acquire overvalued targets. We also find that IPRD write-offs do not increase earnings or stock returns of acquirers after M&As, which is inconsistent with an earnings management hypothesis.
