An Investigation of the Relation between Cooperation Intensity and the Innovative Success of German Regions

Abstract

Concepts like regional innovation systems, innovative milieu and learning regions emphasise the positive contribution of intra-regional cooperation to firms’ innovation performance. This claim is, however, primarily backed by qualitative evidence, as few studies test this issue with quantitative approaches. Using data on co-application and co-invention of patents for 270 German labour market regions, this study shows that cooperation intensity and regions’ innovation efficiency are empirically associated in a negative way. This particularly concerns missing or very extensive inter-regional cooperation. In contrast, medium intensities of regional cooperation have rather positive effects.     

案例教学知识转移机理研究

随着管理学科的不断发展,管理知识的情境性与实践性日益突显,对管理学科的教学提出了更高的要求。作为一种基于案例创设情境,鼓励学生主动实践、互动讨论的教学方法,案例教学法逐渐成为管理学科教学中不可或缺的方法。本文以高校管理学科案例教学为研究对象,通过结构方程模型的实证研究方法探究了案例教学特征通过影响学习者行为从而促进管理知识转移效果的作用机理。实证研究结果表明,案例教学的情境模拟性特征既能够直接促进管理知识的转移,同时也能通过提升学习意愿间接提升管理知识的学习效果,而师生平等性特征则通过影响学〉-7意愿影响管理知识的转移效果,为高校管理学科案例教学的有效开展提供了新的理论依据。

Energy intensity and directed fiscal policy

This paper assesses the effects of fiscal policy on economy-wide energy intensity within an endogenous growth framework. To this end, we first develop a two-sector (investment good and consumption good) augmented AK model by integrating the Uzawa model with Rebelo’s AK model, and assume that a non-renewable resource is one of the factors of production. Using this framework, we solve the model for the short and long run, identifying the sufficient parameter conditions that ensure higher energy intensity in the investment goods sector. We then introduce a balanced budget government, whose objective is to decrease the economy-wide energy intensity by levying tax on the energy-intensive investment goods sector and subsidizing the consumption goods sector. Contrary to our expectations, we find that this fiscal policy design increases economy-wide energy intensity as it leads to a decline in real GDP without changing total energy consumption. On the basis of this model, we propose the concept of a ‘directed fiscal policy’, which connotes a reduction of the economy-wide energy intensity by following a heterogeneous taxation policy across sectors.     

我国城市化进程中工业污染排放强度的实证研究

利用2002—2009年我国省际面板数据,从规模效应、结构效应和技术效应3个角度对我国工业SO2、废气、废水、粉尘、烟尘的排放强度的影响因素进行回归分析,并对城市化水平对工业污染排放强度的影响进行回归分析。结果表明,我国工业污染排放强度与工业规模效应、城市化水平均呈倒U型曲线关系;规模效应、结构效应和技术效应在不同年份对我国工业污染排放强度下降的影响方向和贡献程度有所不同,但总体来看,技术效应的贡献最大;技术水平提高是城市化促使工业污染排放强度下降的主要原因。     

出口企业更清洁吗？——基于微观企业数据的再考察

基于工业企业数据以及环境统计数据,构建1998-2007年面板数据实证分析出口对企业二氧化硫排放强度的影响。回归结果显示：相较于非出口企业,出口企业二氧化硫排放强度较低;企业出口强度越高时二氧化硫排放强度越低。异质性分析发现：企业所属行业以及企业所在地区差异均会对二氧化硫排放强度产生影响。具体表现为,污染密集型制造业行业中,出口企业比非出口企业更为清洁;相较于其他地区而言,东部地区企业出口对二氧化硫排放强度的降低幅度更为显著。在排除两控区环境规制因素对回归结果的影响,并且通过IV(2SLS)以及PSM-DID等方法处理内生性问题后,本文的回归结果依然稳健。机制分析表明：出口企业一方面通过提高新产品产值——R D,另一方面通过提高全要素生产率,降低了企业的二氧化硫排放强度。此外,通过对企业出口状态的改变(广延边际)和企业出口强度的改变(集约边际)的比较发现,出口企业二氧化硫排放强度低的主要驱动因素在于广延边际而非集约边际。     

Foreign direct investment and technical progress in Spanish manufacturing

This article analyses the effects of Foreign Direct Investment (FDI) on technical progress in Spanish manufacturing. Particularly, we study how FDI's contributions vary depending on the economic structure of the industry. The results show that most FDI goes to capital-intensive sectors, especially when those sectors are also Research and Development (R&D)-intensive. Our estimates of the Solow residual show that the positive effect of contemporaneous and lagged FDI on manufacturing productivity is only attributable to capital and R&D intensive industries in what seems to be related to a dynamic capabilities explanation or to complementarities with R&D expenditures.     

Competitive balance versus competitive intensity before a match: is one of these two concepts more relevant in explaining attendance? The case of the French football Ligue 1 over the period 2008–2011

The aim of this article is to investigate the determinants of attendance at French football Ligue 1 matches over the period 2008–2011 with an emphasis on examining the effects of both competitive balance and intensity before a match. Competitive balance is measured by the point difference between the two teams concerned by a match in the championship. Competitive intensity is measured by the point difference for the home team in relation to ranks with sporting stakes. Results show that competitive balance has an insignificant impact whereas competitive intensity has a significantly positive impact. Implications are drawn.     

省会城市中心性研究

城市中心性的研究内容分为两部分,一是中心性指数,另一为中心性程度。省会城市中心性的影响因素包括省区形状、省会位置、省会综合实力、省内地级市实力以及省内交通结构等。文章提出了更为简易的省区形状和省会位置的计量公式,计算了我国各省的形状指数和省会城市位置指数。利用GIS软件,计算出我国各省区经济重心、人口重心、几何重心,并根据这些重心与省会城市位置间的关系,对我国各省最高级中心城市的组合类型进行了探讨。提出中心性程度的概念并探讨了计算方法。文章将影响因素及中心性程度综合考察,对我国部分省会城市的中心性作用不强的原因进行了剖析。其结论对全国省级城市经济区的组织和行政区划调整有一定的借鉴意义。
