我国对外技术依存度的测算及浅析

建设创新型国家成为国家的战略目标,而对外技术依存度的高低成为衡量创新型国家的一个重要指标。针对当前对外技术依存度算法的不足,提出一种全新的测算方法,从技术依存度的内涵出发系统地构造衡量指标和计量模型,运用因子分析方法对我国对外技术依存度进行了测算,并简析其原因。结果显示,中国的对外技术依存度在快速提高,并处于很高的水平,表明我国的技术对外依赖程度非常高,经济技术发展受制于人,我国亟需加强自主创新。     

Assessing time-varying stock market integration in Economic and Monetary Union for normal and crisis periods

In this paper, we examine the stock market integration process amongst 17 Economic and Monetary Union (EMU) countries from January 2002 to June 2013 over a normal period as well as for the Global Financial Crisis (GFC) and Eurozone Debt Crisis (EDC) periods. We classify the economies in three groups (A, B and C) based on their GDP to examine whether the economic size influences financial integration. Seven indicators are used for the purpose, namely, beta convergence, sigma convergence, variance ratio, asymmetric DCC, dynamic cointegration, market synchronisation measure and common components approach. The results suggest that large-sized EMU economies (termed as Group A) exhibit strong stock market integration. Moderate integration is observed for middle-sized EMU economies with old membership (termed as Group B). Small-sized economies (termed as Group C) economies seemed to be least integrated within the EMU stock market system. The findings further suggest presence of contagion effects as one moves from normal to crisis periods, which are specifically stronger for more integrated economies of Group A. We recommend institutional, regulatory and other policy reforms for Group B and especially Group C to achieve higher level of integration.     

Modelo de gestión logística para pequeñas y medianas empresas en México

The market opening and the globalization of supply chains, demand a structural changes in which logistics has a strategic role. Nowadays, clients evaluate product quality, its value added and its availability in time and form, which implies a need to make the process efficient. Several experts have proposed some logistics management models to increase competitiveness in the market, but some of these models are too ambitious for small and medium sized enterprises (SMEs) due to their informal structure and their lack of technical knowledge; other models make indirect reference to the internal information flows, which include whole system disintegration because of the weak interrelation among the different areas. In Mexico, SMEs represent 4.2%, they generate 31.5% of employment and provide 37% of the gross domestic product; that is why it is important to reinforce their competitive position in the market. This research presents the design of a conceptual model of logistic management for SMEs which could provide comprehensive solution through control of the variables involved in the logistics process; to verify that the variables considered in each identified dimension are correct factor analysis was used.     

TEM4改革前后完形填空的考点效度对比分析

2005年以来英语专业四级考试完形填空试题的考点效度比以前有所提高,但句子层次考点数量仍然偏高。教师在教学过程中应注重培养学生的语篇理解能力和逻辑分析能力,提高学生的语言综合运用能力。     

影响农村和谐的因素及其法治对策

农村民主政治不健全、经济文化落后、法律制度不完善、社会矛盾激化是影响农村和谐的主要因素。构建农村和谐,必须加强农村法治,用法治来健全农村民主政治,发展农村经济文化,完善农村法律制度,化解农村社会矛盾。     

技术进步中生产要素产出弹性关系假说及其检验

本研究提出了一个生产要素产出弹性关系假说,即在技术中性条件下,管理要素的产出弹性与劳动要素的产出弹性成正比,与资本要素的产出弹性成反比。通过构建自变量包括资本、劳动和管理要素的简单宏观生产模型,理论上证明了上述假说,经验上利用1970-2006年美国的时间序列数据和OECD七国面板数据也较好验证了假说。这种理论假说的分析和研究结果为我国继续回到经济快速增长的轨道而进行的政策选择空间提供了一个方向性指导。     

我国商业银行风险评价——基于年报数据的因子分析法

基于因子分析法以及商业银行年度报告中常用的经营指标作为风险因子来建立因子分析方程,并对商业银行风险进行评价,以及将评价结果与商业银行管理费用率进行回归后发现,两者之间存在明显的相关关系,商业银行风险评价得分越高,其风险水平就越低,其当年的管理费用率就越低,即商业银行风险管理水平对其当年的经营成本有直接影响。     

劳动要素报酬、人口结构与中国居民储蓄

以动态一般均衡模型为出发点,分析劳动要素报酬、人口结构对居民储蓄率的影响,并运用中国1978～2009年的数据对劳动要素报酬、老人赡养比、儿童抚养比与中国居民储蓄率进行实证检验。研究发现,市场经济转型以来的劳动要素报酬高速增长、老人赡养比上升以及儿童抚养比的下降导致中国储蓄率不断升高,在此基础上给出相应的政策建议。     

基于GIS的成都经济区区域合作层次划分研究

以成都经济区为研究对象,采用SPSS因子分析法和GIS空间分析方法,选择GDP、人均GDP、经济密度、财政收入、社会固定资产投资、工业增加值、城市化率、工业化率八个指标,对成都经济区所辖八市的综合经济水平进行定量分析和空间分析,并结合八市之间的经济距离,应用城市引力模型,测算了成都市对成都经济区其余各市的辐射影响力,基于此得出,成都经济区区域合作分三个层次：首先,成都与德阳、绵阳（1＋2）;其次,成都、德阳、绵阳、眉山、资阳（3＋2）;最后,整个成都经济区八市（5＋3）。     

基于因子分析法的安徽物流能力的研究分析

利用因子分析对安徽各市进行数据整体分析,并建立指标体系得出：安徽区域物流能力综合排名靠前的五个市分别是合肥、芜湖、铜陵、马鞍山、蚌埠,他们都是安徽经济发达的区域,这也证明了区域物流能力的强弱与经济发展有着很大的正相关关系,起着相互促进的作用。安徽省获批唯一以产业转移为主题的区域发展规划,应以此为契机,提高安徽各市的区域物流能力。
