财政扶持及金融联动对地方农民收入影响的空间计量分析

运用空间计量的方法对我国1998—2008年31个省的农民收入及其影响因素数据进行了实证分析.实证结果表明:我国各省市农民收入之间存在明显的空间相关性.从短期来看,农村投资与城市化进程对农民收入增长有显著的促进作用,农村金融与地方财政支持的影响不显著,农村劳动力占农村总人口比重与农业产值占农林渔牧产值比重对农民收入增长具有负向作用.从长期来看,地区城市化水平、农村金融和农村劳动力占比对农村收入的影响不明显,而农村财政投入和农村固定资产投资起到正向的促进作用,农业产值占农林渔牧产值比重起到抑制作用.随着农村经济的发展,影响农民收入的因素进一步多元化,空间因素的影响更加明显.     

基于GRA-DEA模型的有关农民收入的九城市的评价

有关农民收入,文章以山西省九个城市为例进行了评价.首先用灰色关联分析法分析了2016年这些城市的有关数据,筛选出影响农民收入的主要因素;其次构建了指标体系,利用数据包络分析法对有关农民收入九个城市进行了DEA有效性评价;再次对非DEA有效的城市,借助投影公式探索了改进方法;最后得出了九城市分为两类的结论,提出了针对性的建议.     

中国农村正规金融与非正规金融对农民收入增长关系的比较研究

利用1995-2012年农民人均纯收入、农村正规金融融资额和非正规金融融资额的时间序列数据,分别构建农民收入与农村正规金融和非正规金融相关联的A1和A2系统,实证分析了我国农村正规金融和非正规金融对农民收入增长的影响情况.研究结果表明,农村正规金融和非正规金融同农民人均纯收入存在长期稳定的正向关系,在促进农民增收的效率上,农村非正规金融大于正规金融.但是农村正规金融和非正规金融不是农民收入的格兰杰原因,相反农民收入是农村正规金融和非正规金融的格兰杰原因.     

财政支出、电力消费与农民收入的时空特征分析

本文将财政农业人均支出和农村人均用电量作为解释变量,农民人均纯收入作为被解释变量,利用2000-2005年中国31个省、市和自治区的有关时空数据,建立相应的空间自回归模型.模型数据统计分析表明:a)农民人均纯收入不仅存在空间自相关的特点,而且具有异质性;b)农民人均收入对财政农业人均支出、农村人均用电量存在明显的空间依赖性;c)用财政农业支出和农村用电量来反映农民收入水平十分有效,且都具有显著的正面影响.据此,文章提出了一些有针对性的提高农民收入的政策建议.     

物业税的静态一般均衡影响分析

本文分析物业税对城市空间结构的一般均衡影响，体现为对城市中土地价值、房地产租金、城市规模、居民的住房消费行为以及效用水平等的影响。本文在一个静态一般均衡的框架下，假设了一般形式的消费者效用函数，通过比较静态分析得到一些定性的结论。文章重点讨论了CES效用函数的情况，发现对于不同的消费替代弹性，结论可能是完全不同的。比如，在特定的情况下，征收物业税，可能会减少单位土地的资本投入，从而降低土地价值，降低人口密度，导致城市向外扩张；而在另一些情况下，结论正好相反。     

基于因子分析的我国区域经济发展水平研究

为了科学地评价我国各区域经济综合发展水平,选取10个评价指标,采用因子分析法进行实证研究.通过研究,发现收入因子、对外开放度因子和资本投入因子从不同层面上影响了区域经济发展水平.实证结果表明,我国区域经济水平差距极大,各地经济发展不平衡,东部地区经济发展水平明显领先,中东西地区经济综合发展水平较落后.根据地区经济状况,给出提高其经济发展水平的相关建议.     

基于TOPSIS灰色关联投影法的高技术产业技术创新能力动态综合评价——以京津冀一体化为视角

为实现对京津冀地区高技术产业技术创新能力的动态综合评价,文章从技术创新投入、技术创新产出和技术创新环境三个方面建立评价指标体系,采用TOPSIS灰色关联投影法计算灰色关联投影贴近度,引入协调度模型评价区域协调发展水平,并进行二次加权计算。对比所得到的截面静态评价结果和面板动态评价结果,可以看出,京津冀地区高技术产业技术创新能力存在不同程度的波动和较大的地区差异,产业发展处于中度失调状态。研究认为,京津冀应努力加强区域产业合作和优势互补,推动创新资源有效配置,促进产业结构优化升级,不断缩小产业技术创新能力的地域差距,实现一体化发展。     

基于因子分析与数据包络分析的高校专业建设效率评价研究:以辽宁省高校数学与应用数学专业为例

目前高校专业建设质量和效率是教育行政部门关注的热点问题.基于因子分析和数据包络分析方法,对辽宁省16所高校的数学与应用数学专业进行专业建设效率评价.对影响专业建设效率投入和产出指标分别进行因子分析,提取3个投入因子,分别是教师因子、专业课程因子和资源设备因子;提取2个产出因子,分别是科研因子和学生因子,计算出各决策单元的投入产出的分数,再用数据包络分析方法计算出各决策单元的技术效率、纯技术效率和规模效率,指出各高校在专业建设中投入和产出方面的不足之处,优化专业的资源配置,为各高校专业建设和发展提供参考.     

基于多层次模型的广西农民收入问题研究

围绕"三农"问题,打赢全面建成小康社会的扶贫攻坚战,凝聚着全国各族人民的共同夙愿和热切期待.支持革命老区、民族地区、边疆地区、贫困地区的农民增收,实现这些地区农民尽早脱贫更是当前"三农"工作的重中之重.为此,针对广西村庄分布特点,利用农村住户调查微观数据资料,先对不同层次农户收入状况进行分层描述,再基于多层结构模型的分析方法研究了影响广西农户家庭收入的原因,结果表明:有针对性地提高农业生产投入,改善村庄通达条件,合理整合多、小、散、弱、多山的村庄,改变农村基础教育落后面貌,统筹安排,精准扶持,可以确保广西地区农民收入实现可持续较快增长的目标.     

宏观基本面中的稀疏成分与股市波动率预测

利用滚动窗口与规则化回归的方法比较了我国宏观经济基本面中稀疏特征与稀疏因子对股市波动的预测作用，依据回归与预测结果分析稀疏成分预测波动率的机制。研究发现：稀疏因子预测波动率的精度较稀疏特征更高，稀疏特征预测方程包含的更多变量增大了预测方差；预测精度时变性较强且与股市波动负相关，表明引起我国股市震荡的因素一定程度上独立于基本面信息；稀疏特征与因子预测波动率的模式不同，特征预测中市盈率与商品房销售面积增长对波动率预测作用较强，因子预测中波动率自回归项预测作用显著，因子主要起到补充作用。本文研究结论能够为金融风险的防控提供参考。     

Qualitative Analysis of Bifurcating Solutions in the Lengyel-Epstein Model

One of the most fundamental problems in theoretical biology is to explain the mechanisms by which patterns and forms are created in the＇living world. In his seminal paper ＂The Chemical Basis of Morphogenesis＂, Turing showed that a system of coupled reaction-diffusion equations can be used to describe patterns and forms in biological systems. However, the first experimental evidence to the Turing patterns was observed by De Kepper and her associates（1990） on the CIMA reaction in an open unstirred reactor, almost 40 years after Turing＇s prediction. Lengyel and Epstein characterized this famous experiment using a system of reaction-diffusion equations. The Lengyel-Epstein model is in the form as follows     

(0,1 ;0)-INTERPOLATION ON INFINITE INTERVAL (-∞, +∞)

In this paper, we study the explicit representation and convergence of (0, 1; 0)-interpolation on infinite interval, which means to determine a polynomial of degree ≤ 3n - 2 when the function values are prescribed at two set of points namely the zeros of Hn(x) and H′n(x) and the first derivatives at the zeros of H′n(x).     

RECENT PROGRESS ON SPHERICAL HARMONIC APPROXIMATION MADE BY BNU RESEARCH GROUP ——In memory of Professor Sun Yongsheng

As early as in 1990, Professor Sun Yongsheng, suggested his students at Beijing Normal University to consider research problems on the unit sphere. Under his guidance and encouragement his students started the research on spherical harmonic analysis and approximation. In this paper, we incompletely introduce the main achievements in this area obtained by our group and relative researchers during recent 5 years （2001-2005）. The main topics are： convergence of Cesaro summability, a.e. and strong summability of Fourier-Laplace series; smoothness and K-functionals; Kolmogorov and linear widths.     

On a class of self-similar processes with stationary increments in higher order Wiener chaoses

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.     

A REPRESENTATION FORMULA RELATED TO SCHR(O)DINGER OPERATORS

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.     

On a class of Riemann surfaces

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.

An alternative mathematical algorithm for the photo- and videokeratoscope

Due to the resolution of current laser technology, the accuracy of corneal topography as measured by the videokeratoscope is no longer adequate to provide precise enough data for refractive surgery or for the fitting of customized contact lenses. We present an algorithm for recovering corneal topography that makes use of modern differential geometric techniques and numerical descent in Sobolev spaces. We believe this algorithm may be used with the photo- and videokeratoscope to increase the accuracy of the recovered corneal topography.
