针对已有文献研究城镇化时忽视的服务业的空间集聚效应以及经济增长对人口城镇化的非线性关系的问题,文章根据第六次全国人口普查数据,利用半参数空间滞后模型实证研究了我国人口城镇化的影响因素。结果表明:(1)服务业的发展大力推动了我国区域人口城镇化发展,且它的影响强度明显高于工业化发展所带来的影响。服务业集聚效应对该省的人口城镇化具有促进作用,第二产业集聚对该省的人口城镇化的作用不显著。(2)经济欠发达地区(云贵川等)的经济增长对人口城镇化的促进作用较小。而多数位于中部和沿海经济较发达地区(福建、广州等)的经济增长显著促进了人口城镇化的发展。然而,在经济发达地区(如上海、北京、浙江)的经济增长对人口城镇化的促进效果明显开始减弱,甚至是负向的关系。(3)半参数空间滞后模型比普通参数模型具有更高的拟合优度和更丰富的结论,它能够有效刻画城镇化过程中空间相关性与非线性特征。  相似文献

敏感性问题“随机变量和”回答模型   总被引:5,自引:0,他引:5  
孔圣元,孟生旺.敏感性问题“随机变量和”回答模型.数理统计与管理,1998,17(2),35~39.本文依据概率论中“随机变量和”的分布理论,对敏感性问题的调查,提出了一个新模型,即“随机变量和”回答模型,实现了敏感性问题的问卷调查。本文给出了模型的最优估计量及其方差的计算公式,讨论了模型参数的合理选择,同时还得出了一个有趣的结果:“随机化回答模型”包含在“随机变量和”回答模型之中。  相似文献

We study a class of self-similar processes with stationary increments belonging to higher order Wiener chaoses which are similar to Hermite processes. We obtain an almost sure wavelet-like expansion of these processes. This allows us to compute the pointwise and local Hölder regularity of sample paths and to analyse their behaviour at infinity. We also provide some results on the Hausdorff dimension of the range and graphs of multidimensional anisotropic self-similar processes with stationary increments defined by multiple Wiener–Itô integrals.  相似文献

Schr(o)dinger operator is a central subject in the mathematical study of quantum mechanics.Consider the Schrodinger operator H = -△ V on R, where △ = d2/dx2 and the potential function V is real valued. In Fourier analysis, it is well-known that a square integrable function admits an expansion with exponentials as eigenfunctions of -△. A natural conjecture is that an L2 function admits a similar expansion in terms of "eigenfunctions" of H, a perturbation of the Laplacian (see [7], Ch. Ⅺ and the notes), under certain condition on V.  相似文献

It is considered the class of Riemann surfaces with dimT1 = 0, where T1 is a subclass of exact harmonic forms which is one of the factors in the orthogonal decomposition of the spaceΩH of harmonic forms of the surface, namely The surfaces in the class OHD and the class of planar surfaces satisfy dimT1 = 0. A.Pfluger posed the question whether there might exist other surfaces outside those two classes. Here it is shown that in the case of finite genus g, we should look for a surface S with dimT1 = 0 among the surfaces of the form Sg\K , where Sg is a closed surface of genus g and K a compact set of positive harmonic measure with perfect components and very irregular boundary.  相似文献

A cumulative-capacitated transportation problem is studied. The supply nodes and demand nodes are each chains. Shipments from a supply node to a demand node are possible only if the pair lies in a sublattice, or equivalently, in a staircase disjoint union of rectangles, of the product of the two chains. There are (lattice) superadditive upper bounds on the cumulative flows in all leading subrectangles of each rectangle. It is shown that there is a greatest cumulative flow formed by the natural generalization of the South-West Corner Rule that respects cumulative-flow capacities; it has maximum reward when the rewards are (lattice) superadditive; it is integer if the supplies, demands and capacities are integer; and it can be calculated myopically in linear time. The result is specialized to earlier work of Hoeffding (1940), Fréchet (1951), Lorentz (1953), Hoffman (1963) and Barnes and Hoffman (1985). Applications are given to extreme constrained bivariate distributions, optimal distribution with limited one-way product substitution and, generalizing results of Derman and Klein (1958), optimal sales with age-dependent rewards and capacities.To our friend, Philip Wolfe, with admiration and affection, on the occasion of his 65th birthday.Research was supported respectively by the IBM T.J.
