三个不同领域实际问题相结合的教学方法探讨

通过建立肿瘤增长动力学模型,研究肿瘤增长动态规律时发现:肿瘤增长的全过程与龚珀兹增长曲线描述的经济增长过程完全相符;进一步给出了龚珀兹增长曲线与描述种群的增长与调节的逻辑斯蒂增长曲线完全相似.将上述三个属性完全不同的实际应用问题打包传授给学生的授课方法是有别于孤立地介绍三个具体问题的,学生的学习效果也会不同.     

经济增长转型与就业促进

创造就业机会,解决失业问题,已经成为中国政府亟待解决的首要经济发展目标。本文深入分析了改革开放以来经济增长与就业增长之间、资本增长与就业增长之间、工资增长与就业增长之间的关系,并进一步深讨了经济转轨各个阶段就业模式的变化,以及正规就业与非正规就业对就业增长的影响。在此基础上,作者明确指出,经济增长与投资增长对扩大就业的作用正逐渐削弱,宏观经济政策与就业政策的改革也不足以彻底缓解就业压力,解决失业问题的关键在于实现经济增长模式从"经济增长优先"向"就业增长优先"型的转变,正确处理和协调劳动力密集型产业与资本密集型产业之间、劳工利益与资本利益之间、扩大内需与创造就业之间的关系。     

A prediction of individual growth of height according to an empirical Bayesian approach

An empirical Bayesian approach is applied to a prediction of an individual growth in height at an early stage of life. The sample has 548 normal growth of Japanese girls whose measurements are available on request. The prior distribution of estimator of the growth parameter vector in a lifetime growth model is obtained conventionally from the least squares estimates of the growth parameters. The choice of prior distributions is discussed from a practical point of view. It is possible to obtain a relevant prediction of growth based upon only measurements during the first six years of life. The lifetime prediction of individual growth at the age of 6 is enough approximation of real measurements obtained. This report deals with the comparison between the least squares estimates and an empirical Bayes estimates of the growth parameters and the characteristic points of the growth curve. We discuss the mean-constant growth curves of the groups classified by the height intervals at the age of 6.This work was supported in part by the ISM Cooperative Research Program (2-ISM·CRP-63).     

The Growth Matrix of the Sale

The model of the sale based on the growth matrix shows a double aspect of growth: one which is related to the direct growth rates and which expresses the intensity of sales, and another which is related to the indirect rates and shows a relative sales growth of one product in relation to another. The indirect sales growth provides us with knowledge about the relative relations of the sales growth. By simultaneous observation of the direct and indirect growth rates, we are in a position to find out the absolute and relative changes of sales during a period of time, and through the matrix of growth we present a complete structure of the sales growth.     

价格贸易条件对经济增长影响的实证研究——基于混频数据马尔科夫区制转移模型

为研究不同经济增速状态下价格贸易条件对经济增速的影响,基于1994年1月至2018年12月的月度价格贸易条件及1994年1季度至2018年4季度的季度实际GDP增长率的混频数据,建立马尔科夫区制转移模型并进行实证分析.研究结果表明:在经济平稳增长状态,价格贸易条件情况改善对我国经济增速有正向影响.在经济快速增长状态,伴随着价格贸易条件情况恶化,经济增速有所提升,但作用不明显.采用马尔科夫区制转移模型研究我国GDP增长率序列更具合理性.

A Comparative Analysis of Co-Operating Enterprises on the Basis of a Growth Matrix

A matrix and submatrix of growth of co-operating enterprises enable fuller investigation of relations between enterprises. They contain relatively important parameters and enable immediate inview into the direct growth of enterprises as well as into their mutual movements. A submatrix of growth represents a general scheme of growth of the ith and jth enterprise and by aid of it, investigations of complex structural relations can be performed. Through the submatrix of growth movements of enterprises can be linked and the following can be investigated: (1) relations of absolute levels of the production of enterprises in different periods, (2) absolute and relative rates of growth of enterprises and (3) direct and indirect elasticities of growth of enterprises. Through these parameters a comparative dynamic and structural analysis of co-operating enterprises can be performed.

Effects of growth volatility on economic performance - Empirical evidence from Turkey

This paper examines the relationship between growth and growth volatility for a small open economy with high growth volatility: Turkey. Quarterly data for the period from 1987Q1 to 2007Q3 suggests that growth volatility reduces growth and that this result is robust under different specifications. This paper contributes to the literature by focusing on how growth volatility affects a set of variables that are crucial for growth. Empirical evidence from Turkey suggests that higher growth volatility reduces total factor productivity, investment, and the foreign currency value of local currency (depreciation). Moreover, it increases employment, though the evidence for this is not statistically significant.

中国金融发展与经济增长关系及同步性研究:兼对二者关系实证结果矛盾的解释

关于金融发展与经济增长的关系,不同学者的研究结果存在较大矛盾.采用格兰杰因果检验、协整、岭回归、成长曲线、聚类分析综合研究了二者之间的关系,发现银行贷款余额比率及广义货币发行量比率是经济增长的格兰杰原因,但经济增长不是广义货币发行量比率和银行贷款余额比率的格兰杰原因.工商业贷款余额不是经济增长的格兰杰原因,但经济发展对工商业贷款的增长有一定的贡献.广义货币发行量比率和银行贷款余额比率对经济增长都有显著的贡献,前者略大,工商业贷款比率对经济增长有负面影响.银行贷款余额的成长曲线和经济增长是同步的,但是广义货币发行量在改革开放初期滞后于经济增长,近几年又快于经济增长,二者并不同步,主要与中国实行的投资为主的经济发展路径及过度的货币发行量有关.作者认为有3个原因导致不同学者对金融发展与经济增长关系矛盾的结果,一是金融发展的度量方法存在困难;二是短期研究数据难以获得;三是研究方法本身存在的偏误问题.     

Growth of primary decompositions of Frobenius powers of ideals

It was previously known, by work of Smith–Swanson and of Sharp–Nossem, that the linear growth property of primary decompositions of Frobenius powers of ideals in rings of prime characteristic has strong connections to the localization problem in tight closure theory. The localization problem has recently been settled in negative by Brenner and Monsky, but the linear growth question is still open. We study growth of primary decompositions of Frobenius powers of dimension one homogeneous ideals in graded rings over fields. If the ring is positively graded we prove that the linear growth property holds. For non-negatively graded rings we are able to show that there is a “polynomial growth”. We present explicit primary decompositions of Frobenius powers of an ideal, which were known to have infinitely many associated primes, having this linear growth property. We also discuss some other interesting examples.     

A Matrix of a Growth Optimization Model for the Production Activity of Cooperating Enterprises

This paper deals with direct and indirect growth rates of co-operating enterprises and with the corresponding matrix of growth. Its purpose is to determine through indirect growth rates the growth structure of co-operating enterprises and to construct, on the basis of the matrix of growth, a model which enables us to follow and program them. In other words, by means of the matrix of growth or the model which is based on it we can estimate the future development of co-operating enterprises. The conditions of optimality have been determined through linear programming, whereby account has been taken of the upper and the lower limit of development of the enterprise, the available funds and the efficiency of investments.

Growth factor and expected growth factor of some pivoting strategies

Several definitions of growth factors for Gaussian elimination are compared. Some new pivoting strategies, intermediate between partial pivoting and rook pivoting, are introduced. For random matrices, an approximation of the average normalized growth factor associated with several pivoting strategies is computed and analyzed. A stationary behavior of the expected growth factors of the new pivoting strategies is observed. Bounds for the growth factors of these pivoting strategies are provided. It is also shown that partial pivoting by columns produces small growth factors for matrices appearing in practical observations and for which the growth factors produced by partial pivoting are very large.     

Growth tightness of free and amalgamated products

We show that every nontrivial free product, different from the infinite dihedral group, is growth tight with respect to any algebraic distance: that is, its exponential growth rate is strictly greater than the corresponding growth rate of any of its proper quotients. A similar property holds for the amalgamated product of residually finite groups over a finite subgroup. As a consequence, we provide examples of finitely generated groups of uniform exponential growth whose minimal growth is not realized by any generating set.     

The morphological stability of dendritic growth from the binary alloy melt with an external flow

The morphological stability of dendritic growth from the binary alloy melt with an external flow is studied by means of the matched asymptotic expansion method and multiple variable expansion method. The uniformly valid asymptotic solution is obtained for the case of the large Schmidt number. The analytical result reveals that the stability of dendritic growth depends on a critical stability number above which dendritic growth is stable. The selection condition of dendritic growth determines the Peclet number, tip growth velocity, tip radius and oscillation frequency, which is significantly affected by the external flow. The stability mechanism of dendritic growth in the binary alloy melt with the external flow remains the same as that in pure melt. In the binary alloy melt with the external flow the solute concentration destabilizes the dendritic growth system. The numerical computation for various growth conditions demonstrates the variations of the critical stability number, tip growth velocity, tip radius, and oscillatory frequency with the undercooling, external flow and morphological number.
