经济带:新发展阶段的新愿景

经济带已成为承东启西、连南贯北的"经济主骨架",在国民经济整体格局中的战略地位日益凸显,对我国经济发展具有重大战略意义.经济带的形成有其深刻的理论基础和现实条件,我国"两横"——长江经济带和陇海兰新经济带,以及"三纵"——沿海经济带、京广京哈经济带、包昆经济带五条经济带,需要进一步集聚经济要素,破除要素流动壁垒,提升节点城市能级,推动区域经济合作,以经济带建设推动我国经济高质量发展.     

Monitoring the foreign exchange rate benchmark fix

ABSTRACT

We develop a Manipulation Index (ManIx) that captures the potential manipulation intention of dealers during the World Markets/Reuters (WMR) benchmark (London Close) period at 4 pm London time through a unique algorithm and simulation. The application of this model (using a dataset with dealers’ identities) can identify banks that are prone to potential manipulative behavior. The results concerning the identified banks are validated by the regulatory investigations. Implementation of this algorithm allows regulators better direct their limited resources towards more targeted in-depth investigation.     

中国高端装备制造业自主技术创新效率稳定性及影响因素研究

在全面实施创新驱动发展战略的时代背景下，揭示中国高端装备制造业自主技术创新效率稳定性，测度相关因素的影响强度与方向，对揭示中国高端装备制造业自主技术创新规律，制定其发展策略具有重要指导意义。聚焦中国高端装备制造业自主技术创新效率稳定性及影响因素，采用DEA-Malmquist指数方法和Tobit回归模型进行实证研究，结果表明，中国高端装备制造业自主技术创新效率存在一定波动性，且各细分行业技术创新效率内部稳定性较差，产业自主技术创新效率整体稳定性不高；自主技术创新投入因素和环境影响因素对产业自主技术创新效率的影响具有较高的异质性，其中创新资金投入和人力资源投入对自主技术创新综合效率、纯技术效率及规模效率具有正向影响，而新产品开发投入和企业规模对自主技术创新综合效率、纯技术效率和规模效率的影响具有异质性，政策因素与市场因素分别具有显著和非显著负向影响，外源性创新因素具有显著正向影响，且影响强度较大。在此基础上，提出调整政府对高端装备制造业创新支持模式、加强外源性创新与智力引进等策略建议。     

INTERNATIONAL RESERVE MANAGEMENT: A DRIFT‐SWITCHING REFLECTED JUMP‐DIFFUSION MODEL

We study the cost of shocks, that is, jump risk, with respect to reserve management when the reserve process is formulated as a drift‐switching jump diffusion with a reflecting barrier at 0. Inspired by the Brownian drift switching model, our model results in a more realistic dynamic behavior of international reserves than the buffer stock model. The new model can capture both the jump behavior in reserve dynamics and the leptokurtic feature of the increment distribution which has a higher peak and two asymmetric heavier tails than the normal distribution. Through the selection of an initial distribution that reflects certain steady state behaviors, the reserve process becomes a regenerative process. This selection enables us to derive a closed‐form expression for the total expected discounted cost of managing reserves, thus helping us to numerically find management strategies that minimize costs. The numerical results show that shocks at the reserve level have a significant effect on reserve management strategies and that model misspecification can result in nonnegligible additional costs.     

Machine Learning and Expert Judgement: Analyzing Emerging Topics in Accounting and Finance Research in the Asia–Pacific

In this paper, we focus on the question to what extent machine learning (ML) tools can be used to support systematic literature reviews. We apply a ML approach for topic detection to analyze emerging topics in the literature—our context is accounting and finance research in the Asia–Pacific region. To evaluate the robustness of the approach, we compare findings from the automated ML approach with the results from a manual analysis of the literature. The automated approach uses a keyword algorithm detection mechanism whereby the manual analysis uses common techniques for qualitative data analysis, that is, triangulation between researchers (expert judgement). From our paper, we conclude that both methods have strengths and weaknesses. The automated analysis works well for large corpora of text and provides a very standardized and non-biased way of analyzing the literature. However, the human researcher is potentially better equipped to evaluate current issues and future trends in the literature. Overall, the best results might be achieved when a variety of tools are used together.     

我国高等教育招生与就业的矛盾性分析

随着高等教育规模的扩大及社会经济的转型，高校招生与就业之间的矛盾日益呈现，其深层次的原因除了扩招本身之外，还主要源于体制的滞后，高校办学主体的不确定性，市场需求的失衡，受教育者本体能力和行为的失缺。     

基于RFID技术的末端产品信息管理研究

对末端产品的处理一直是学术界关注的问题，文章将RFID技术引入末端产品的物流信息管理，跟踪产品的整个生命周期，记录产品维修、报废、更换等信息，这些信息将减少末端产品的检测环节并有助于末端产品处理方法决策的制定，从而提高末端产品物流的效率。

浅谈利用无损压缩技术制作高品质的数字音乐

APE是目前流行的一种无损音频压缩格式,与MP3这类有损压缩方武不同,它采用高达800～1200kbps进行压缩,接近于音乐CD的1411.2kbps,远远高于MP3的128kbps的音质.利用Monkey's Audio这个音频处理软件可以将CD唱片压缩成APE格式的数字音乐以便在互联网上传播;APE下载后也可通过Monkey's Audio或foorbar2000等解压成VAV格式文件并刻录成CD.     

与生活贴近与读者贴心--浅谈地方党报践行"三贴近"中的亲民意识

“地方媒体报道更要贴近实际、贴近生活、贴近群众，多反映基层干部群众的生动实践和新鲜经验，多为人民群众的工作、学习、生活提供健康有益的新的信息”。这是以胡锦涛同志为首的党中央对新闻工作者提出的新要求，是广大人民群众在新的历史时期对新闻传媒的深情呼唤，也是地方党委机关报自身生存和发展的客观需要。从客观现实来看，地方党报与读者的时问、空间距离是最近的，与读者的交流最直接、最频繁．读者脉搏的跳动，公众视线的焦点，寻常百姓的喜怒冷暖，这一切总会牵动着地方党报的神经。因此地方党报有条件、也最有内在要求通过深化亲民意识来践行“贴近实际、贴近生活、贴近群众”。
