绿色建筑经济激励政策分析

绿色建筑难以推广的原因是绿色建筑的经济外部性问题,而解决外部性问题的通常做法是政府干预。我们从经济学的角度,对经济激励政策的原理进行了分析,除此之外,还重点对绿色建筑的外部经济性和非绿色建筑的外部不经济性进行剖析,最后我们提出了一些促进绿色建筑产业发展的建议。     

Central Bank's interventions and the Fisher hypothesis: a threshold cointegration investigation

The long-run relationship between nominal interest rates and inflation is examined, allowing for structural breaks and asymmetric mean reversion. From a Threshold AutoRegressive (TAR) test applied to the residuals of the cointegration relationship (while allowing for both a break in the mean of the long-run equation and a smooth regime-transition), there is strong evidence for non-linear mean reversion properties for the real interest rates of the US Treasury Bill market. This suggests asymmetric changes to inflation shocks in the Central Bank's reaction function. The existence of different regimes is consistent with some interpretations of the monetary policies run by the Fed, such as credibility and opportunism.     

Regional, national, and spatially explicit scenarios of demographic and economic change based on SRES

We report here spatially explicit scenario interpretations for population and economic activity (GDP) for the time period 1990 to 2100 based on three scenarios (A2, B1, and B2) from the IPCC Special Report on Emissions Scenarios (SRES). At the highest degree of spatial detail, the scenario indicators are calculated at a 0.5 by 0.5 degree resolution. All three scenarios follow the qualitative scenario characteristics, as outlined in the original SRES scenarios. Two scenarios (B1 and B2) also follow (with minor adjustments due to scenario improvements) the original SRES quantifications at the level of 4 and 11 world regions respectively. The quantification of the original SRES A2 scenario has been revised to reflect recent changing perceptions on the demographic outlook of world population growth. In this revised “high population growth” scenario, A2r world population reaches some 12 billion by 2100 (as opposed to some 15 billion in the original SRES A2 scenario) and is characterized by a “delayed fertility transition” that is also mirrored in a delayed (economic) development catch-up, resulting in an initially stagnating and subsequently only very slow reduction in income disparities. The spatially explicit scenario interpretation proceeds via two steps. Through a combination of decomposition and optimization methods, world regional scenario results are first disaggregated to the level of 185 countries. In a subsequent second step, national results are further disaggregated to a grid cell level, taking urbanization and regional (rural–urban) income disparities explicitly into account. A distinguishing feature of the spatially explicit scenario results reported here is that both methodologies, as well as numerical assumptions underlying the “downscaling” exercise, are scenario-dependent, leading to distinctly different spatial patterns of population and economic activities across the three scenarios examined.     

基于共生关系的创意产业集群形成机制——上海18个创意产业集群实证

以上海18个创意产业集群为分析对象,利用共生模型对创意产业集群之间的形成机制进行实证研究。研究结果表明,互利共生关系是创意产业集群形成的逻辑起点,互利共生关系越贴近于对称互利共生关系,则创意产业集群效应越好,从而越有利于创意产业集群的形成和稳定发展,且共生关系质量越好。

科研开发与经济增长——兼论科研开发的溢出效应

经济划分为科研部门和非科研部门，科研开发对经济增长的作用及科研对非科研部门具有外溢效应。1999-2003年30个省市自治区的面板数据表明，科研开发对经济增长具有较大的拉动作用，同时科研开发部门对其他部门的外溢作用明显为正。

Do liquidity induced changes in aggregate dividends signal aggregate future earnings growth?

Extant empirical literature does not provide abundant evidence for the information content hypothesis regarding firm-level dividend signaling. Although this is consistent with the argument against an optimal firm-level dividend policy, this does not imply an absence of an optimal aggregate dividend level. Aggregate dividends and earnings may exhibit stronger associations if aggregation filters out firm-specific earnings information and indicates macroeconomic trends. Using macroeconomic data, we show that aggregate payout ratios signal aggregate future earnings growth for horizons up to 4 years, and that excess aggregate liquidity plays an important role in this relationship.

FDI对湖南省的经济增长效应及其地域梯度差异的实证分析

通过回归分析法,实证分析外商直接投资(FDI)对湖南省经济增长的影响,并采用Q型聚类层次法进一步探讨FDI对湖南各地区经济增长影响的不平衡性。结果表明:FDI对湖南省经济促进效应显著,且主要是靠短期需求拉动经济增长,FDI的滞后期为3年,滞后的FDI对经济的贡献小于当年对GDP的贡献。FDI对省内各地区经济的贡献表现出相当大的差异性,且这种差距呈扩大态势,值得引起高度警惕。
