Generalised K-S confidence regions: some exact results

One-sided confidence regions for continuous cumulative distribution function are constructed using empirical cumulative distribution functions and the generalized Kolmogorov-Smirnov distance. The band width of such regions becomes narrower in the right or left tail of the distribution. Significance levels necessary for implementation are given. Some other K-S type distances useful in constructing a confidence region with nonconstant width are also included.     

On an asymptotic relative efficiency concept based on expected volumes of confidence regions

ABSTRACT

The paper deals with an asymptotic relative efficiency concept for confidence regions of multidimensional parameters that is based on the expected volumes of the confidence regions. Under standard conditions the asymptotic relative efficiencies of confidence regions are seen to be certain powers of the ratio of the limits of the expected volumes. These limits are explicitly derived for confidence regions associated with certain plugin estimators, likelihood ratio tests and Wald tests. Under regularity conditions, the asymptotic relative efficiency of each of these procedures with respect to each one of its competitors is equal to 1. The results are applied to multivariate normal distributions and multinomial distributions in a fairly general setting.     

论西北地区资源开发与生态环境保护的制度建设

脆弱的生态环境是制约西北地区发展的首要因素,而传统的生产经营模式必将进一步加剧生态环境的破坏,必须放弃。西北地区资源开发与生态环境治理之间形成尖锐矛盾的深层次原因在于人与人之间的利益分配和责任分担失衡,即具有有限理性的利益主体以社会公众和他人利益为代价来换取自身利益最大化,但却不承担相应的社会责任。因此,要促使西北地区生产经营方式发生根本性转变,就必须以利益调整为核心,以生态环境保护主体的行为特点为逻辑起点,以切实可行的成本机制和激励机制为根本措施和有力保障。     

Revisiting the flexibility and regularity properties of the asymptotically ideal production model

In this paper we estimate the flexibility properties and regular regions for the first three orders of the seminonparametric Asymptotically Ideal Model (AIM) under four different types of constant returns to scale production technologies. The AIM model's parameters are estimatedfrom a Monte Carlo simulation where the data is generated from a three input, one output, globally regular Constant Differences of Elasticity of Substitution function. The Monte Carlo's input quantity and elasticity of substitution estimates at the unit vector are graphed along with the area of the relative price space where the AIM model is monotonically increasing andquasi-concave.     

从增长极理论看西部地区技术发展能力

技术能力的提高是西部地区得以发展的重要条件,西部地区总体技术能力较差,同时技术能力地域分布不平衡,存在若干技术增长极,若能合理发挥其作用,将会极大地促进西部地区经济和技术的进步。     

技术进步、人力资本溢出、政府作用与西部经济增长

西部经济的发展有赖于正确运用内生增长理论,重视科学技术,建立健全人力资本的激励和约束机制,充分发挥人力资本的作用。政府应制定优惠政策吸引货币资本和人力资本流向西部地区,以实现西部经济的持续增长。     

Research on the Path of City-industry Integration in Different Types of Regions from the Humanistic Perspective

City-industry integration is the key path to realizing new urbanization. City-industry integration from the perspective of humanism will ultimately achieve the harmonious symbiosis and sustainable development among industries, cities and human beings. With the deepening of the urbanization process, the research scope of city-industry integration should not be confined to the new urban areas, but also the central cities and small towns. Different types of regions have different problems due to different stages and characteristics of their industries and urbanization,therefore, we should explore the path of city-industry integration based on differentiation and local conditions. The central city should adhere to the principles of industrial transformation and upgrading, paying equal attention to urban development and protection, and improving urban quality,and it should take the path of upgrading industries and urban development. New urban areas should follow the principles of humanism, matching urban functions with industrial development, green development and sustainable development,and it should take the path of synchronous and balanced development. Small towns should embrace the principle of driving the development by characteristic industries and serving the modernization of agriculture and rural revitalization, and it should take the path of internal integration of industrial characteristics and urban characteristics.     

省际R&D技术溢出对碳排放的影响

CO2排放增多是全球变暖的主要原因,技术进步对碳减排的作用日益受到各方重视。基于地理经济距离构建省际技术溢出网络,将省际R&D直接技术溢出与用网络中心度度量的间接技术溢出引入碳排放影响因素分析的面板计量模型,利用2000—2013年中国29个省、市、自治区面板数据进行实证分析。结果表明:全国范围内,省际R&D直接溢出对碳排放有显著的抑制作用,间接效应不明显。分地区看,东、中部地区省际R&D直接溢出与碳排放显著负相关,西部地区不显著。省际R&D间接溢出可以显著减少中部地区碳排放,东部地区以接近中心度衡量的省际R&D间接溢出与碳排放显著正相关,西部地区以特征向量衡量的省际R&D间接技术溢出与碳排放显著正相关。     

西部大开发环境下的西部历史文化名城保护

对西部历史文化名城时空特征和文化特色分析表明,西部34座名城都有其独特历史文化内涵,而地方特色、民族特色、环境特色则是创造这些特色的基础和制约条件。随着西部大开发带来的社会经济进步以及由此引发的西部人文和自然环境变化,西部历史文化名城保护与开发工作应当调整思路,树立整体、系统的保护开发观,建立由5个层次构成的完整的保护开发体系。     

IMD国际竞争力评价技术及其应用——以中国区域国际竞争力评价为例

文章对瑞士洛桑国际管理学院(IMD)国际竞争力评价体系作了简要介绍,并解读其综合评价方法。同时针对IMD将国家内部经济体(如中国浙江省)纳入其参评体系后带来的评价技术和理论问题展开了讨论。最后利用IMD评价技术对中国东部10省市国际竞争力加以实证研究。
