创新价值链视角下的区域创新活动收敛分析

基于创新价值链视角,将我国创新活动分为知识创新、科研创新、产品转化创新3个阶段,运用空间面板收敛模型对各类创新活动进行收敛检验,研究结果显示：①空间自回归因子和扰动项的空间滞后因子对创新增长率有显著正向影响,说明创新水平增长在地区间具有显著的空间效应,存在空间示范效应和外生冲击传递效应,同时空间面板模型拟合效果整体上优于普通面板模型,说明我国创新活动收敛中有必要考虑空间因素;②知识创新和知识转化创新水平存在稳定的绝对β收敛,科研创新水平不存在收敛,通过基尼系数时序图验证了我国科研创新活动存在“马太效应”,另外两类创新活动水平则朝着收敛的趋势发展;③高校资源、市场化水平分别对知识创新和产品转化创新收敛有显著促进作用,信息化水平对三大创新活动收敛都有显著的促进作用。     

服务主导逻辑下服务创新价值共创机理及对策研究

随着全球服务业的飞速发展,传统产品主导逻辑已经难以适应如今的变化与发展,服务主导逻辑开始取代产品主导逻辑。同时,协同创新正日益成为企业发展的不竭动力和源泉。为了更深入地研究服务主导逻辑,在归纳和分析国内外协同创新研究成果的基础上,对服务主导逻辑下的服务创新价值共创进行研究,分析价值共创的创新相关方和创新轨道,并结合其它创新方式,构建服务创新价值共创系统,最后提出相应的管理建议和对策,以期为服务型企业提供有益建议,实现价值共创。     

Estimating the Marginal Contribution to Systemic Risk by A CoVaR‐model Based on Copula Functions and Extreme Value Theory

In this paper, we quantify the contribution to systemic risk of a single financial institution by utilizing a analytical framework based on the principles of Extreme Value Theory (EVT) for modelling the marginal distributions and on the properties of copula functions for describing the dependence structure between the financial system and the single financial institution. Among the several systemic risk measures proposed nowadays by academics and estimated by public data, we choose to adopt as systemic risk metric the Conditional Value‐at‐Risk (CoVaR). We select a co‐risk measure like the CoVaR because of its macro‐dimension that allows us to integrate the dependence structure of the single financial institution and of the whole financial system in the systemic risk measurement. While the copula functions have been utilized in some pioneer studies on this area, the EVT principles have not yet been implemented in such a context of systemic risk contribution measurement.     

农村金融网点扩张与县域资金外流——基于2005-2012年县域经验证据

本文对金融网点信息进行"县级-乡镇级"识别,并匹配2005-2012年的县域社会经济面板数据,以研究农村金融市场化对县域资金外流的影响。研究表明:(1)农村金融机构大量扩张对县域地方资金外流存在当期和延期影响,每新增一家金融网点将增加6元的当地人均外流资金;(2)金融机构导致地方资金外流存在规模效应,新增机构使当地资金显著外流2-3年后达到新的平衡状态;(3)金融机构导致资金外流在东西部区域间存在显著差异。农村金融机构是农村地区资金外流的重要渠道,资金外流既不利于农村地区经济发展的同时也不利于金融机构的长期发展。     

Peer effects in computer assisted learning: evidence from a randomized experiment

We conduct a large scale experiment to investigate peer effects in computer assisted learning (CAL). Identification relies on three levels of randomization. We find an average 0.17 standard deviation improvement in math scores among primary school students. This average effect is the same for students treated individually or in pairs, implying that peer effects double the learning benefit from a given equipment. Among paired students, poor performers benefit more from CAL when paired with good performers and vice versa. Average performers benefit equally irrespective of who they are paired with. This suggests that the treatment is dominated by knowledge exchange between peers. We also find that CAL treatment reduces the dispersion in math scores and that the beneficial effects of CAL can be strengthened if weak students are systematically paired with strong students.     

产业技术创新战略联盟的性质、分类与政府支持

产业技术创新战略联盟是合作研发的组织模式之一,承载着产业发展的目标,通过合作研发取得产业共性技术,并在联盟和全行业中扩散,最终实现产业竞争力的提升。产业共性技术的复杂性和准公共品性质、联盟合作创新的困境,决定了政府支持产业技术创新战略联盟的必要性。产业技术创新战略联盟有多种类型,政府应针对不同类型的联盟提供不同的支持。在明确产业技术创新战略联盟的内涵及性质的基础上,按照3个维度对其进行了分类,并借鉴国外经验给出了当前我国政府提供政策支持的建议。     

Institutions and geography: Empirical test of spatial growth models for European regions

This article provides an empirical assessment of the growth experiences of European regions, during the period 1991–2004, by taking into account the spatial effects due to both institutions and geography. These effects have been modelled by means of specific controls and by using a non-conventional spatial weight matrix. Results favour a model dealing with substantive spatial externalities. Within this framework, the country-specific institutions are strongly and positively related to the regional productivity's growth rate. In addition, the geo-institutional proximity increases the spatial dependence of the regional output per worker and raises the speed of convergence. By contrast, the pure geographical metrics is underperforming, while underestimating the convergence dynamics.

Both China and Japan Are Winners

In recent years, there have been comments or predictions from both official and folk circles in Japan about when Chinas GDP will surpass that of Japan. In the middle ,of August, Japan＇s official statistics showed that in the second quarter this year, Japan fell behind China in GDP, which was reported by Japan＇s major media. This is not a novel topic, so the media did not show any sign of shock. Even so, we can still sense different and completed reactions from Japan＇s public opinion on its ＂being surpassed＂.
