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＂.

Asymmetry in mobile access charges: is it an effective regulatory measure?

This paper analyses the regulation of the market of voice call termination on mobile networks, by considering the remedy of asymmetric access charges and the hypothesis of discriminatory retail pricing. In the two way interconnection, the operators revenue depends on two factors: the retail price and the access charge. If the retail prices are different between calls that terminate on the same network (on-net) and calls that terminate on the rival network (off-net), the competition is more complex, involving positive networks externalities for the incumbent operator. In order to reduce the competitive disadvantage for new entrants and smaller operators many European regulation authorities have introduced the remedy of asymmetric access charges. This paper is aimed at analysing the effectiveness of this regulatory measure, assuming that operators are differentiated in terms of brand loyalty and cost structure.     

基于虚拟经济视角的资本积累与金融监管

从虚拟经济视角认识当代资本积累、价值化积累已成为一种新的积累制度.这种制度一方面鼓励财富创造,另一方面资本的逐利本性导致投机活动在各类资产之间和各金融市场之间迅速转换,系统性风险增大,实体经济与虚拟经济严重失衡,金融危机频繁爆发.中国资本市场对外开放进入新阶段,从虚拟经济理念出发强调金融监管的整体性、全局性和动态性,有利于防范金融风险,保障国家安全.
