如何面对国际金融危机和不断变化着的国内实践,是中国共产党必须要解决的重大理论和实践课题。胡锦涛同志"七一"重要讲话运用发展了的马克思主义对变化了的国内外形势做了最新的哲学概括,从历史唯物主义的基本原理出发提出了继续坚持以经济建设为中心,坚持经济、政治、社会、文化四位一体的和谐发展,用发展的马克思主义指导新的实践等重要思想,给我们当前及今后较长一段时间的发展指明了方向,是我们应该长期坚持的重要指导思想。     

ENTRY BARRIERS,COMPETITION, AND TECHNOLOGY ADOPTION

I build a model of technology adoption to study the quantitative effect of entry barriers on total factor productivity (TFP). In my model, incumbent firms choose technologies that are sufficiently productive to deter entry from a potential competitor. I show that higher entry barriers help to deter entry and lead to the choice of less productive technologies. A novelty of my work is that I use a direct measure of entry barriers. I find that reducing entry barriers from their average level in the poorest 30% of countries to their U.S. level leads to a sizeable increase in aggregate TFP of 12%. (JEL O11, O43)

开放经济下OFDI对产业结构升级效应及传导路径

开放经济下对外直接投资(OFDI)已成为我国融入世界经济的主要途径,在优化产业结构、推进经济转型等方面扮演着重要角色。根据OFDI与产业结构升级及传导路径的互动机理分析,在对安徽省OFDI投资概况和产业结构现状进行分析的基础上,选取2003—2017年相关数据为样本构建VAR模型,运用ADF检验、脉冲响应函数等方法从产业结构总水平角度,实证分析得出短期内安徽省OFDI所能带来的产业结构升级效应并不显著的结论。进而从具体传导路径角度,采用主成分分析法,从10个变量中提取主成分构建VAR模型,运用脉冲响应等方法实证分析得出安徽省OFDI可通过贸易、省内投资、就业和技术路径来促进产业结构升级。为此,安徽省应扩大OFDI规模,提升OFDI质量和效益;增强企业竞争实力和科技创新能力,优化对外投资结构;发挥政府宏观调控和政策引导作用,加大对企业的扶持力度。     

田径运动训练过程控制理论研究述评

基于国内外相关文献,对田径运动训练周期理论、运动负荷控制理论、训练过程控制模式以及田径运动训练过程控制理论等进行综述.当前学术界在田径运动训练周期划分、训练结构等方面已经形成了统一的意见,但对训练周期的安排还存在部分分歧.关于运动负荷控制理论的研究是在适应人体能力的基础上进行的,而训练过程中控制模型的研究则是从数学以及专项训练等方面切入的,对田径运动员身体体能、训练强度承受能力以及运动内容等方面的研究呈现出交叉融合应用的态势.尽管以上研究有一定的局限性,但也为运动负荷理论以及训练过程控制理论打下了坚实的理论基础.     

美国中小企业技术创新计划管理实践及启示——以TIP为例

美国技术创新计划(TIP)支持有科技优势的中小企业进行目标明确的变革性技术研发,以促进中小企业的技术创新和提升美国的竞争力。它的资助与管理具有支持企业面向国家需求的变革性研究、设立专门的咨询委员会、坚持以同行评议进行项目遴选等基本特点,以及具有把扁平化的组织管理与"跨办公室"工作模式相结合、"自上而下"与"自下而上"相结合、实行全过程管理与结果管理相结合等工作机制。它为我国科技计划管理改革带来的重要启示在于要面向国家产业需求,支持和引导中小企业的变革性技术研究;倡建中小企业创新联盟,鼓励高校、科研院所为中小企业服务;加强后评估研究工作,重视影响评估对科技计划管理的作用。     

我国球类制造业核心技术竞争力研究——基于篮、排、足球专利分析

文章利用数理统计方法对我国三大球制作近十年的专利申请信息进行了整理加工和定量分析,结果表明,2005-2014年中国三大球专利技术处于发展阶段,并逐渐趋于成熟,三大球专利技术创新能力大幅度提高,但技术交叉程度不高;球门架、球体及照明装置等领域要避免重复研究,电信号装置和电通信技术等领域是未来三大球专利技术研发的重点;三大球科技创新能力主要集中在山东、浙江、江苏、黑龙江和广东五个球类制造业较为聚集的省份。研究旨在能为我国三大球产品制造业企业提高核心技术竞争力提供一些有益信息。     

Empirical Bayes estimation in continuous one-parameter exponential families under associated samples

In this paper, we study the empirical Bayes (EB) estimation in continuous one-parameter exponential families under negatively associated (NA) samples and positively associated (PA) samples. Under certain regularity conditions, it is shown that the convergence rates of proposed EB estimators under NA or PA samples are the same as those of EB estimators under independent observations, which significantly improve the existing results in EB estimation under associated samples.

工程质量政府监督多层次利益分配与激励协同机制探究

The implementation of the government supervision of the quality of the project is an international practice. The basic form of government supervision of engineering quality is government supervision on the quality behavior of the engineering main bodies and its results by the competent government department entrusted. Its essence is a dual principal-agent process. The frequent accidents of the engineering quality reflect the loss and failure of the government law enforcement supervision of the engineering quality to some extent. Its root lies in the lack of endogenous power in the law enforcement supervision of the project quality government supervisors in the law enforcement supervision. Therefore, the incentive coordination mechanism of the government supervision based on the multi-level interest distribution is worth explored. In views of the multi-level management system which is formed by the government departments, government quality supervision organizations, quality supervision team (or group) for the government supervision of engineering quality. The benefit distribution function between every party is constructed, and the game model of the multi-level incentive and coordination for the government supervision in engineering quality is built. To solve and deduce from the first stage of the cooperative game and the second stage of the non-cooperative game, the cooperative game can obtain the reward coefficient: . The coordination degree of the best effort can be obtained by the non cooperative game. The result shows that:the coordination degree of government engineering quality supervisor is related to the coordination costs, and had nothing to do with fixed costs. The benefit distribution coefficient not only depends on the efforts of the quality government monitors, but also on the efficiency of other parties' efforts. The quality supervisors of the project will also focus on the coordination with other parties when enhancing their management capabilities to improve the overall performance of project quality government supervision. The strategy of the incentive coordination mechanism for the supervision and cooperation of the project quality government is:the government quality supervision team should set up the supervisory team properly, improve the coordination efficiency and reduce the cost of supervision-coordination to maximize the value of self-motivation. Quality supervision team (or group) should establish the partnership to improve the coordination efficiency for achieving the maximization of their own incentive value.The model and conclusion of incentive synergy mechanism based on multi-level benefit allocation mechanism are researched. It can provide theoretical support and practice reference for the market governance and supervision of general public goods.
