区域技术创新及其影响因素的空间计量分析

利用空间统计的Moran指数和空间截面数据模型,对影响我国区域技术创新的因素进行计量分析。结果表明：区域创新环境对我国区域技术创新为显著的负效应;大学和创新企业对我国区域技术创新有显著的促进作用;研究机构对我国区域技术创新没有显著的贡献;创新企业对提高技术创新能力的贡献最大。     

要素自由流动能实现区域协调发展吗——基于“协调性集聚”的理论假说与实证检验

经济活动的空间集聚是当代经济内涵式增长的源泉,现有文献多从要素流动视角来考察经济集聚过程中的区域差异。然而,若将要素流动引入区域生产函数进行推导,可以发现非区域性要素集中规模的扩大,既能提高要素流入区域的劳动生产率,也能提高要素流出区域的要素收益率,基于此,本文以“协调性集聚”为核心概念,通过拓展现代集聚模型来构建要素在自由流动中走向协调发展的理论假说。实证结果进一步显示,虽然我国发展要素在大规模流向东部发达地区,并呈现进一步向超大城市和城市群集聚的趋势,但要素流动在提高要素流入区域劳动生产率的同时,也显著提高了要素流出区域的要素收益率,并从需求侧激发了要素流出区域的市场潜能,要素流动在要素配置效率不断提高的过程中呈现“协调性集聚”的趋势。因此,发达的要素流入区域通过优化公共服务体系提高劳动生产率,欠发达的要素流出区域通过建立健全要素自由流动机制提高要素回报率和收益率,是新时代我国形成市场主导型区域协调发展机制的有效途径。     

交通基础设施与经济增长:中国区域差距的视角

本文利用中国28个省市区1987—2007年的面板数据来验证交通基础设施对中国经济增长的影响,同时还检验交通基础设施在中国区域经济差距中所扮演的角色。基于一个巴罗类型的增长模型以及对该模型进行分解,本文的实证结果表明:交通基础设施对中国的经济增长有着显著的正向促进作用;不同的地理位置和交通基础设施条件在我国区域经济发展差距中扮演了重要的角色;1999年国家实施西部大开发战略有利于促进西部地区的经济增长与向中东部地区趋同,其中,西部地区交通基础设施的快速发展发挥了重要作用。     

Africa’s single aviation market: The progress so far

To promote the development of air transport at the continental level, several policies were introduced, leading to the Yamoussoukro Decision (YD) in late 1999, which had the liberalisation of the intra-African aviation spaces as its main objective. Even though notable progress has been achieved towards more market-oriented aviation policies, at the pan-African level some markets are still restrictive and inconsistent with the YD, particularly with respect to the granting of 5th freedom rights. This paper aims to examine recent developments in the aviation sector in Africa, with a focus on the implementation of the YD. The obstacles to liberalisation are discussed and several measures for facilitating Africa’s move towards multilateral open skies are investigated. These include, among others, a greater collaboration and co-operation among African airlines, as well as between African airlines and foreign ones; redefinition of the role and responsibilities of different institutions which are instrumental in implementing the YD and some further issues such as ownership guidelines.     

货币政策地区效应——基于地区总供给曲线的理论与实证分析

本文着重检验了我国区域经济中的基于产出缺口的地区短期总供给曲线的存在性,进而分析地区短期总供给曲线对货币政策地区效应的影响。文章首先对地区短期总供给曲线存在的可能性进行了理论解释,应用卡尔曼滤波方法估算了我国各地区的产出缺口,然后运用ARMA模型说明预期通货膨胀率形成机制,最后以通货膨胀率与其预期之差、外部需求冲击等作为解释变量对产出缺口进行回归,结果发现,我国东部地区的短期总供给曲线较中西部地区的短期总供给曲线更平坦,因而东部地区货币政策效应要强于中西部地区。     

对我国区际经济与金融差距关联性的实证分析

各区域间金融发展的差异对经济发展差距有无影响以及影响机制如何成为经济学研究的一项任务。以塞尔指标衡量我国经济与金融发展差距,发现我国区域间经济发展差距与金融发展差距呈现一致的变动关系,且金融差距大于经济差距。由此引出的基本判断是我国区际经济差距的逻辑原因有金融因素,进而采用格兰杰因果关系检验判断我国省际金融发展与经济增长间的关系,从中可以明确我国东部地区金融成长偏重于内生状态,而中西部地区更倾向于外生状态。考虑到改革的总体方向,并借鉴东部地区的经验,放松金融抑制、催化内生金融成长无疑是全面促进中西部经济发展的必然选择。     

Success factors of university-spin-offs: Regional government support programs versus regional environment

In recent years entrepreneurship research has increasingly interpreted new firm emergence in the light of the context the potential or real founder is living and working in. This is especially true for university spin-offs, a type of new firms that gives rise to great hopes for policymakers and technology transfer institutions. The aim of this paper is to analyze what is more influential: specific characteristics of the regional environment of the spin-off founder or public programs to support university spin-offs. Based upon a unique data set covering 11 years of data collection we were able to apply a control group approach with two different government support programs in two regional contexts. The results based upon ordinal regressions suggest that the regional context in which an individual starts a firm, has an impact on start-up success, but the fact that he/she had received government support has a lesser impact. To summarize: site specific factors matter, government support programs per se do not.
