Optimal Timing of Climate Change Policy: Interaction Between Carbon Taxes and Innovation Externalities

This paper addresses the impact of endogenous technology through research and development (R&D) on the timing of climate change policy. We develop a model with a stock pollutant (carbon dioxide) and abatement technological change through R&D, and we use the model to study the interaction between carbon taxes and innovation externalities. Our analysis shows that the timing of optimal emission reduction policy strongly depends on the set of policy instruments available. When climate-specific R&D targeting instruments are available, policy has to use these to step up early innovation. When these instruments are not available, policy has to steer innovation through creating demand for emission saving technologies. That is, carbon taxes should be high compared to the Pigouvian levels when the abatement industry is developing. Finally, we calibrate the model in order to explore the magnitude of the theoretical findings within the context of climate change policy.      

中国改革开放以来财政政策平滑经济波动的能力——基于传统IS-LM模型的实证分析

文章通过借助传统IS-LM模型和比较静态分析方法对中国改革开放以来财政政策平滑经济波动的能力进行了实证分析,得出:(1)财政政策对经济波动的整体平滑能力较低,平均只有6.35%,财政政策的平滑能力在经济波动的不同状态之间存在明显差异;(2)财政政策工具之间的平滑能力存在较大差异,其中财政购买性支出能平滑掉经济初始冲击的11.48%,而财政转移性支出和收入政策整体上反而使经济波动上升近3%;(3)内生性检验表明,中国只有相机性支出政策与经济波动之间存在显著的双向因果关系,不仅如此,相机性支出政策的内外时滞都较短。文章结论的政策含义是,提高中国财政政策稳定效果的关键在于提高政策工具的有效性与相互之间的协同效应,不仅如此,对经济高涨时期政府财政行为进行有效约束也至关重要。     

中国汽车产业的外向发展与节能减排

中国汽车产业的产销量一直呈现良好的上升趋势。但在金融危机下,受国内外环境和政策的影响,中国汽车产业产销量的增速有所放缓,汽车的价格受市场竞争程度和供求状况等因素的影响出现了波动。为了保证中国汽车产业的平衡发展,更好地实现可持续发展,需要加快汽车产业节能减排的步伐。     

创新型科技人才的典型特质及培育政策建议——基于84名创新型科技人才的实证分析

对84名创新型科技人才的研究发现,创新意识和创新能力、深厚的专业积累与稳定的研究方向、敏锐的观察力、严谨的方法和系统思维能力是创新型科技人才的4个典型特质。培育创新型科技人才,政府要重点塑造有利于创新的教育文化,发挥科技评价的创新导向作用,完善高层次人才的引进政策。各类科研机构也要加强对科技人才的教育培训,建立符合科技人才成长规律的科技评价体系,从薪酬体系、选拔机制、发展渠道和科研基础建设等方面强化对科技人才的创新激励。     

Assessing the regional digital divide across the European Union-27

Despite the efforts devoted to the analysis of the digital divide over the last years, the regional evidence on this issue is still scarce. Within this context, the goals of this paper are twofold: (1) measuring the digital divide across the regions of the 27 Member States and within each country and (2) explaining the observed regional disparities. The analysis leads to identify Dutch regions as the Top-10 in ICT, while Greece and Bulgaria occupy the Bottom-10. Therefore, results show that the regional digital divide reflects to some extent the income gap. However, regional policy seems to be having some positive implications for technology adoption. In particular, the rural-versus-urban dimension of the digital gap appears to be less important than it is usually claimed to. Likewise, some evidence is found of the role of cultural and institutional factors in ICT adoption, an issue that has not been previously analyzed at the regional level.     

Interplay between internal investment and alliance specialization in R&D and marketing

A firm's efforts to build its technological and marketing capabilities are not limited to internal investments but can be extended to include external knowledge acquisitions. We examine the interaction between a firm's specialization in R&D or marketing through its internal investments and its alliances in two different industrial contexts. Our results, based on secondary data sources such as Compustat and SDC Platinum from 1985 to 2009, show that the interaction effects of internal specialization and alliance specialization are contingent on the types of tasks (i.e., R&D and marketing) and the industrial context (i.e., high- and low-tech industries). Our findings indicate that a firm in a high-tech industry is able to achieve greater gains by complementing its internal focus on R&D with its external focus on marketing or by focusing on R&D both internally and externally. In contrast, a firm in a low-tech industry is able to achieve greater performance when R&D and marketing complement each other, without regard for how they are aligned through internal investments and alliances. The firm is also able to improve its performance by focusing on marketing both internally and externally. These findings provide new insights into the complementarity between internal investments and alliances.     

Management training in small and medium-sized enterprises: methodological and conceptual issues

The paper examines the impact of management training and development on the organisation and performance of small and medium-sized enterprises (SMEs), via a variety of quantitative and qualitative research techniques and including both crosssectional and longitudinal approaches to analysis. The paper demonstrates the value of management training and development in SMEs and demonstrates a series of one-off and longer lasting effects on their organization and performance. The paper also highlights the conditions under which management development projects are likely to be more successful. Finally, the paper extends the schema developed by Arthur and Hendry (1990) and Hendry et al. (1991), indicating the factors influencing training within businesses, and shows the indirect and complex links between management training and firm performance.     

我国城市污水处理投融资模式的实证研究

本文结合博弈论和计量经济学的Eview5工具对我国城市污水处理过程中各投资主体和资金来源进行实证研究,结果表明:民间资本在城市污水处理投融资过程中的地位越来越重要,所起作用已经超过政府资本;政府资本效用的下降,说明了政府资本使用效率低的问题,但政府在整个过程中监督管理的角色不会变。接下来我国城市污水处理的投融资模式将以市场化为主,政府资本为辅这一基本思路进行选择。
