房地产正向财富效应形成的条件分析

房地产对居民消费的财富效应一直是关注的焦点。产生房地产财富正效应的条件为:城市居民二套住房拥有率要大于有潜在住房购买力的家庭占比率。我国应加大调控力度,降低房价,增加公共住房保障供给,大力发展适合中低收入阶层家庭的商品房项目。     

控股股东所有权、双向资金占用与盈余质量

文章以我国上市公司2003-2005年的数据为样本,检验了控股股东所有权、双向资金占用和盈余质量之间的关系。研究发现,控股股东所有权与应计项目之间存在倒\"N\"型曲线关系;在控股股东持股较少时,控股股东通过占用上市公司资金降低了盈余质量,与所有权防御效应一致;当控股股东持股较多时,控股股东所有权与盈余质量之间呈现不显著的正相关。文章认为,如果控股股东通过双向资金占用影响盈余质量,那么盈余质量是低的;如果控股股东没有通过双向资金占用影响盈余质量,双向资金占用行为本身也会降低盈余质量。文章最后提出政策建议。

Does economic growth and energy consumption drive environmental degradation in China’s 31 provinces? New evidence from a spatial econometric perspective

The panel data analysis points to economic and social factors contributing to NO_x, PM_2.5, PM₁₀, SO₂, and VOCs in China’s 31 provinces. The spatial correlation analysis using Global and Local Moran’s I values indicates the existence of a significant and positive spatial autocorrelation with respect to environment, economy and energy, and the high spatial correlation is evident in the eastern region, covering the northern part of Yangtze River Delta, Huaihai Economic Zone, and the lower reaches of the Yellow River Economic Belt. The empirical estimation is performed through spatial lag and spatial Durbin models. All emitted air pollutants in 31 provinces have significant spatial dependence and strong spillover effects. There is an inverted U-shaped relationship between emitted air pollutants (NO_x, PM₁₀, VOCs, and PM_2.5) and per capita GDP, which follows the EKC hypothesis. The relationship between SO₂ and per capita GDP does not follow the EKC hypothesis. There is a positive relationship between pollutant emissions and coal consumption, which is consistent with current studies for various countries like Canada, Denmark, UK and US and regions like New York State. However, the effects of science and technology investment on air pollutants are mostly positive, which is not as policy expected.     

广义虚拟经济视角下农业领域FDI的技术溢出

以广义虚拟经济视角观察我国农业领域外商直接投资（FDI）活动,可以发现,FDI效应分为物质态表现形式与信息态表现形式。对FDI信息态的有效利用,不仅与东道国的经济发展水平有关,而且与科研人员积极性以及创新能力有关。本文基于我国1999-2011年的省际面板数据,利用负二项回归模型分析我国农业领域外商直接投资（FDI）的技术溢出效应,并利用面板数据的非线性门槛效应模型,分析我国农业领域FDI技术溢出差别的条件,结果表明只有科研人员积极性以及自主创新能力达到一定水平,FDI的信息态才是可吸收的。     

Wagner’s law versus displacement effect

The public sector has grown dramatically over the past few centuries in many developed countries. In this article, we use wavelet methods to distinguish between two leading explanations for this growth – Wagner’s law and the displacement effect. In doing so, we use the long-term data of 10 OECD countries for a maximum time span of 1800–2009. We find that the validity of Wagner’s law is likely to vary strongly over time for each country. A roughly similar feature in most of the countries is that the law is less valid in the earliest stage of economic development as well as in the advanced stages, with the validity tending to follow an inverted U-shaped pattern with economic development. Further, our results indicate that the long-run growth of government size cannot be adequately explained by Wagner’s law. On the other hand, the displacement effect appears to account for the bulk of the growth in most of the countries.     

社会资本对企业营销的影响

社会资本对企业营销的影响具有双重性,既存在积极作用,也会产生消极影响。社会资本对企业营销的积极影响表现在降低代理成本、提高营销组织工作效率、推动开放式营销组织治理模式的构建、提供更多商业机会和提高顾客满意度等5个方面;社会资本对企业营销的消极作用则表现为竞争的扭曲和营销的僵化两个方面。
