科技金融投入、技术创新与产业结构升级

科技金融投入对产业结构优化升级具有重要影响作用。本文基于2011~2019年的省际面板数据,使用固定效应模型对中国30个省份进行实证分析,并使用工具变量解决内生性问题。研究结果表明,科技金融投入对产业结构的影响呈现"倒U型"的非线性特征;从作用机制来看,科技金融投入影响技术创新进而作用于产业结构升级;从地区上来看,科技金融投入对产业结构升级的影响在东部地区表现明显,中、西部地区作用不明显。据此,提出加快完善科技金融制度、完善多层次资本市场体系、注重高技术人才的培养、平衡地区发展等政策建议。     

Financial liberalization,financial sector development and growth: Evidence from Malaysia

The objective of this paper is to examine whether financial development leads to economic growth or vice versa in the small open economy of Malaysia. Using time series data from 1960 to 2001, we conduct cointegration and causality tests to assess the finance-growth link by taking the real interest rate and financial repression into account. The empirical evidence suggests that financial liberalization, through removing the repressionist policies, has a favorable effect in stimulating financial sector development. Financial depth and economic development are positively related; but contrary to the conventional findings, our results support Robinson's view that output growth leads to higher financial depth in the long-run.     

Downside Risk

Economists have long recognized that investors care differentlyabout downside losses versus upside gains. Agents who placegreater weight on downside risk demand additional compensationfor holding stocks with high sensitivities to downside marketmovements. We show that the cross section of stock returns reflectsa downside risk premium of approximately 6% per annum. Stocksthat covary strongly with the market during market declineshave high average returns. The reward for beasring downsiderisk is not simply compensation for regular market beta, noris it explained by coskewness or liquidity risk, or by size,value, and momentum characteristics.

基于组织模块化的价值网研究

在企业所处的商业生态系统中，随着价值链的延伸、分解和网络化，企业的内部网络和外部网络联结起来，形成一个开放的价值网，价值的创造、交换和共享分布在整个网络中。在价值网中，逐渐形成了不同职能、不同层次的组织模块，组织模块化构成了价值网的组织基础。本文的实践意义在于为企业在网络经济中的竞争战略提供指导：企业之间的竞争已演变为其所属的价值网的竞争，企业必须致力于构建基于价值网的竞争能力：模块化能力、控制协调能力、关系管理能力。     

What Drives the Historical Formation and Persistent Development of Territorial States?

The importance of the length of state history for understanding variations in income levels and growth rates across countries has received a lot of attention in the recent literature on long‐run comparative development. The literature, however, is silent about its origins. This paper explores the determinants of statehood by considering the potential roles of an early transition to fully‐fledged agricultural production, the adoption of state‐of‐the‐art military innovations, and the opportunity for economic interaction with the regional economic leader. The results demonstrate that only the association between economic interaction and the rise and development of the state is statistically robust.     

Brands as cultural resources in children’s peer culture

This article examines how children collectively appropriate brands as cultural resources. From the New Childhood Studies perspective, an ethnographic study was conducted in schools to investigate the engagement of 10- to 11-year-old children in brand culture. The findings demonstrate that, through a process similar to Corsaro’s model of interpretive reproduction, children do not simply reproduce brand culture; instead, they actively use branding to fuel their peer culture. Mastering and manipulating brands are thus sources for integration or exclusion within the peer group and for differentiation from the adult world. We show the paradoxical impacts of branding on children’s well-being and participate in the debate on their vulnerability to marketing by highlighting how they deploy brand culture to interact in their social spheres, with the consequence being that their would-be empowerment remains entangled in the “brandscape.” Last, we contribute to a better understanding of the concept of culturally based brand literacy.     

智慧BIM乔木模型：从设计图纸到施工 现场

现有的BIM应用软件提供的乔木模型多为RPC或高 精度3D模型等3D CAD类型。这些模型着重于表达美感或进 行展示，无法反映根系情况。虽然可能包含一定附加属性，但 表达乔木生长和空间需求的功能有限。因而，冲突检查、工序 调度等BIM的优势功能无从应用。风景园林实践领域已就此问 题开始构建自己的模型库，但能够准确反映现状树木真实尺寸 体量，以及现状树木和规划树木未来空间需求的模型仍未广泛 出现。提出一种基于树冠、树干和根系构型与生长功能的实体/ 网面封装建模方法构建BIM乔木模型。模型形态通过一组参数 调整，并根据树龄和反映环境限制因子的值来反映其变化。所 包含的数据和参数数量随后期设计阶段所需的LoD(详细层级) 及专业实践的具体要求而增加。该模型可以与提供本地区内外 苗木商品信息的植物数据库连接使用。

The Unintended Consequences of High Expectations and Pressure on New CEOs

We provide empirical tests of a general version of targeting theory that greater scrutiny could lead to executive abuses. Our results show that new CEOs under higher expectations or pressure are more likely to report meeting analyst forecasts; however, this apparent superior performance dissipates after excluding firms having characteristics synonymous with earnings manipulation. We find evidence that new CEOs under greater pressure are considerably more likely to engage in manipulation while the link between expectations and manipulation is much weaker. The results are strongest for new CEOs whose firms report meeting forecasts and do not “walk down” earnings estimates.     

Private saving in India and Malaysia compared: the roles of financial liberalization and expected pension benefits

In this article, we provide a comparative account of the evolution of private saving in India and Malaysia, and analyze how policy changes in the financial sector and pension system help explain differences in their saving performance. Using the Autoregressive Distributed Lag (ARDL) bounds estimation procedure, we find a fairly robust long-run relationship between private saving and its determinants in both countries. Consistent with the predictions made in the life cycle model, our results indicate that higher income growth stimulates private saving and an increase in age dependency retards private saving. The results provide some support for the hypothesis that financial liberalization results in lower private saving in both countries. The evidence also indicates that expected pension benefits tend to stimulate private saving in India, but that the reverse is found in Malaysia.
