开放经济下OFDI对产业结构升级效应及传导路径

开放经济下对外直接投资(OFDI)已成为我国融入世界经济的主要途径,在优化产业结构、推进经济转型等方面扮演着重要角色。根据OFDI与产业结构升级及传导路径的互动机理分析,在对安徽省OFDI投资概况和产业结构现状进行分析的基础上,选取2003—2017年相关数据为样本构建VAR模型,运用ADF检验、脉冲响应函数等方法从产业结构总水平角度,实证分析得出短期内安徽省OFDI所能带来的产业结构升级效应并不显著的结论。进而从具体传导路径角度,采用主成分分析法,从10个变量中提取主成分构建VAR模型,运用脉冲响应等方法实证分析得出安徽省OFDI可通过贸易、省内投资、就业和技术路径来促进产业结构升级。为此,安徽省应扩大OFDI规模,提升OFDI质量和效益;增强企业竞争实力和科技创新能力,优化对外投资结构;发挥政府宏观调控和政策引导作用,加大对企业的扶持力度。     

学习迁移的系统理论:PPEE理论模型的建构和意义

学习是人类社会永恒的主题。为了更好地利用过去的经验，增强学习效果，个人和组织进行学习迁移具有重要意义。学习迁移是指将在以往通过学习或解决问题所获得的经验，用于解决之后所遇到的问题。本文力图建立系统的学习迁移理论，研究人、问题、环境的因素对于学习迁移的影响。本文采用理论推导的研究方法，在前人研究的基础上，提出相应的理论模型。本文运用系统的观点，构建了学习迁移的PPEE理论模型，认为人的因素、问题的因素、人和问题的交互作用、以及环境的调节作用，会共同影响学习迁移的效果。本理论主要从五个方面论述学习迁移的机制。首先，将人的因素按照不同层面划分为后端基本能力、中端心理过程、前端知识结构，讨论了其各自对学习迁移效果的直接影响。其次，将问题的因素划分为形象相似性和抽象相似性，并根据这两个维度构建了四种问题间关系类型，并探究了其与学习迁移效果之间的关系。第三，同时考虑人的因素和问题的因素，研究了二者之间的互动对于学习迁移效果的影响。第四，将环境因素划分为时间紧迫性和空间重要性两个维度，探讨了人和环境，以及问题和环境之间的互动对学习迁移效果的影响。第五，基于系统整体的方面，研究人、问题、环境三者之间的互动对学习迁移效果的交互影响。本文还认为，该模型不仅适用于个人，也同样适用于团队、组织、地区、甚至国家和社会等各个层面，影响各个层面主体的学习迁移。本文最后总结了研究的理论和实践贡献，并提出了未来研究课题。本文对丰富学习理论、特别是学习迁移理论，以及推动教育和管理实践的发展进步具有重要的意义。     

儒家“义—利”价值结构与西方“财富”价值结构比较研究简

通过中国儒家和西方经济价值结构的比较研究，发现儒家以“义一利”为价值结构模型，西方以“财富”为价值结构模型。儒家价值结构的基本特征是“义体利用”，表现方式是：强国的道义在于顺天时、尽地利、忠人和；安国的道义在于民朴民富；治国的道义在于蓄储俭用。西方价值结构的基本特征是“利体义用”，表现方式是：鼓励获取财富、财富规则和财富责任。儒家“义一利”价值结构与西方“财富”价值结构是两种不同的价值评判话语体系，在中国现代“义利共体”的价值结构建构中，儒家价值结构提供着人文精神基础，西方价值结构提供着物质文明建设可资借鉴的经验。     

Bootstrap order selection for SETAR models

In this paper, we investigate the selecting performances of a bootstrapped version of the Akaike information criterion for nonlinear self-exciting threshold autoregressive-type data generating processes. Empirical results will be obtained via Monte Carlo simulations. The quality of our method is assessed by comparison with its non-bootstrap counterpart and through a novel procedure based on artificial neural networks.     

Modifying the Modifier: Body Modification as Social Incarnation

The notion that body modification occurs when one undertakes practices like tattooing, piercing or scarification, engenders discourses in which: (i) body modifiers endorse such practices as self‐constructive, distancing their practitioners from social regulation and a deterministic biology, whereas; (ii) critics condemn their seemingly violent, corporeal interference. However, in suspecting that such analysis should be attentive to the concurrent individual and social co‐constitution of behaviours, a sociological and post‐structural interrogation of this characterization of body modification as a “sovereign, denaturalizing” endeavour is demanded. An engagement with the originary violence of Derridian deconstruction will duly re‐conceive body modification practice as not something which introduces violence to corporeality. Rather, violence will present as a primordial differentiating process which bodies always already condition, and by which they are conditioned/produced/modified. The second issue at stake in this article will thus develop as a contestation to the characterization of “body modification” as an exclusive category of practice. Such practices do not arrive, pre‐existing, but rather manifest as the originary violence/differentiation of bodies‐as‐modifications‐which‐modify. This re‐defines modification from something that agentive subjects introduce to bodies, to something that subjects‐as‐bodies cannot help but be. Consequently, individual agency is not divorced from behaviour, but emerges as a corporeal, social production.

Trying to stay ahead of the curve in Chile's economic development: exploring a way out of the middle‐income trap through pragmatic export development

Underneath impressive growth levels, the Chilean economy displays signs of being caught in a middle‐income trap. It has been unable to improve its productivity, increase the added value of its exports or upgrade its value chain. Its economy cannot compete either with low‐wage countries or highly productive, innovative countries. Its export strategy based on export promotion seems to have outlived its usefulness. It achieved remarkable quantitative success, but must now attend qualitative attributes. Instead of regarding market‐driven export promotion and state‐led export development as substitutes, this article proposes to view them as alternatives in different stages of development. To choose the appropriate time, more attention should be given to non‐traditional, structural indicators, like export sophistication and political‐institutional capabilities.

Modeling probability density through ultraspherical polynomial transformations

We present a method for fitting parametric probability density models using an integrated square error criterion on a continuum of weighted Lebesgue spaces formed by ultraspherical polynomials. This approach is inherently suitable for creating mixture model representations of complex distributions and allows fully autonomous cluster analysis of high-dimensional datasets. The method is also suitable for extremely large sets, allowing post facto model selection and analysis even in the absence of the original data. Furthermore, the fitting procedure only requires the parametric model to be pointwise evaluable, making it trivial to fit user-defined models through a generic algorithm.
