浅议“全国公安机关现场勘查信息系统”在新经济形势下的应用

"全国公安机关现场勘验信息系统"是公安机关"金盾工程"和"三基工程"的重点建设项目,是刑事技术现场勘验检查的信息平台,自2009年6月正式建库以来取得了巨大成效。特别是在新经济形势下,该信息系统在铁路公安机关的广泛应用,分析在应用中遇到的问题及解决途径,有利于其作用在铁路公安机关更好地发挥。     

零售商买方势力一定会导致通道费吗？--基于纵向市场结构的合作博弈分析

关于通道费的研究,有一种观点认为通道费是零售商买方势力的体现。但是现实经济中有些具有买方势力的零售商收取通道费,而另一些却不收取通道费,买方势力的观点不能对这一现象作出解释。针对此,构建双边双寡头的纵向市场结构模型,并在模型中引入零售商的价格竞争和服务竞争,在合作博弈的框架下分析研究了零售商买方势力与通道费之间的关系。研究发现买方势力并不是出现通道费的充分条件,而只是必要条件,通道费的出现与否除了与零售商买方势力有关外,还与其他的市场环境因素有关。最后,通过线性需求函数的特例对这一结论进行了验证,并在此基础之上提出了相应的规制政策建议。     

China’s direct investment in the European Union: challenges and policy responses

The dramatic rise of Chinese direct investment into the European Union (EU) has sparked a debate about the control that China may be seeking to take over European economies. Quite naturally, these concerns have led to repeated calls that action be taken to slow down, if not to halt entirely, this growing trend. The objective of the article is to shed light on this debate. Following a thorough analysis of Chinese direct investment in the EU, this article suggests that the challenges posed by these inflows are widely overblown. Despite this, the article concludes that it is necessary to have a systematic approach to regulating inbound foreign investment (including from China) in the EU. Such an approach may help guard against the risk of a protectionist drift inside the EU, as well as the possibility that some investors may one day pose a threat to national security. This article concludes that although the current fragmented regulatory approach is unsatisfactory, because of the difficulties associated with a unified EU-wide review process, the most realistic option is to promote a more systematic and coordinated use of existing mechanisms such as competition policy. Also, pushing for the negotiation of a China–EU BIT is certainly a promising avenue to enhance the EU’s bargaining leverage based on the principle of positive reciprocity.     

政府财政行为对劳动收入占比的影响——基于2004—2011年中国省级面板数据的实证分析

运用广义矩估计法(GMM)并利用2004—2011年中国省级面板数据,考察了中国政府的财政收支行为及其他相关因素对劳动收入占比的影响,并对实证结果进行了稳健性检验。研究结果表明:政府的财政支出行为与劳动收入占比的关系曲线呈显著的倒U型,在样本观察期内两者正相关,引入时间虚拟变量后政策效果更加明显;政府的财政收入行为对劳动收入占比的影响为负;第三产业占比、资本深化、劳动保护等因素对劳动收入占比具有正向影响,人力资本、对外贸易等因素对劳动收入占比具有负向作用。     

地方政府税收竞争对产能过剩的影响

使用2001—2011年我国省际面板数据,测算了我国30个省(自治区、直辖市)的产能过剩程度,进一步实证检验了地方政府的税收竞争对产能过剩的影响。结果表明:产能过剩主要出现在重工业领域;地方政府的税收竞争加剧了重工业的产能过剩程度,其中增值税竞争的影响大于总税收竞争和企业所得税竞争的影响,地方政府税收竞争的滞后影响大于当期影响;在中、西部地区,地方政府的税收竞争对重工业产能过剩的影响更为显著。指出:减弱地方政府的税收竞争有利于缓解我国产能过剩问题。     

可标准化服务行业对服务业发展的影响——基于两部门模型的分析

从理论上探讨了标准化促进服务业发展的内在机制。构建了两部门模型,分析了可标准化服务部门对服务业发展的影响。利用2003—2012年中国服务业的省际数据,运用面板模型对可标准化服务部门的溢出效应进行了估算,利用DEA方法对服务业各行业的全要素生产率进行了测算和分解。结果表明:可标准化服务部门要素的边际产出高于不可标准化服务部门,发展可标准化服务部门有利于服务业增长;可标准化服务行业对不可标准化服务行业的溢出效应为负,原因在于可标准化服务行业的全要素生产率较低,因此在当前发展阶段需要进一步对可标准化服务行业内部进行优化整合。     

地方政府支出竞争与地区投资行为——中国式财政分权框架下的实证研究

中国财政分权体制下,地方政府间的财政支出竞争广泛存在。建立纳入财政支出分权、地方政府财政支出及支出竞争的企业投资决策计量模型。结论显示:地方政府财政支出横向竞争和纵向竞争对地区投资行为影响具有差异性并存在长期效应。为实现地方政府支出竞争的良性发展应将更多的资源投入到有利于提高地区整体投资环境的领域,同时继续完善中央和地方关系。     

刺激还是抑制：企业负债对广告投入影响的理论与实证研究

以布莱德和莱维斯的理论为基础,假设广告具有拓展效应和窃取效应,研究企业负债与市场地位对企业广告投资的影响。结果显示：企业资本市场行为影响其产品市场竞争,负债具有竞争策略性;企业负债刺激其广告投入,而竞争对手负债抑制其广告投入;寡头垄断市场,企业初始市场份额抑制其广告投入;广告投入具有行业差异,且非制造业内部差异更大。研究结论拓展布莱德和莱维斯研究的同时,也给企业广告投资提供参考价值。     

Verti-zontal differentiation in export markets

Many trade models of monopolistic competition identify cost efficiency as the main determinant of firm performance in export markets. To date, the analysis of demand factors has received much less attention. We propose a new model where consumer preferences are asymmetric across varieties and heterogeneous across countries. The model generates new predictions and allows for an identification of horizontal differentiation (taste) clearly distinguished from vertical differentiation (quality). Data patterns observed in Belgian firm–product level exports by destination are congruent with the predictions and seem to warrant a richer modelling of consumer demand.     

How to derive consensus among various marketing journal rankings?

Despite the increasing popularity of journal rankings to evaluate the quality of research contributions, the individual rankings for journals that ranked below the top tier of publications usually feature only modest agreement. Attempts to merge rankings into meta-rankings suffer from some methodological issues, such as mixed measurement scales and incomplete data. This paper addresses the issue of how to construct suitable aggregates of individual journal rankings, using an optimization-based consensus ranking approach. The authors apply the proposed method to a subset of marketing-related journals from a list of collected journal rankings. Next, the paper studies the stability of the derived consensus solution, and the degeneration effects that occur when excluding journals and/or rankings. Finally, the authors investigate the similarities/dissimilarities of the consensus with a naive meta-ranking and with individual rankings. The results show that, even though journals are not uniformly ranked, one may derive a consensus ranking with considerably high agreement with the individual rankings.
